N62 Valve Stems Seals - What was your cost
 

DIY or shop ?

I'm curious on the N62 stem seal repair. There was the recent blurb about the local master tech doing it as a side job for $2500 and knocked it out in less than a day.

I was just at my Indy this weekend for him to scan the car for a airbag light and we were chatting for a bit. I did not go into much details but he mentioned the stem seal failures on N62 and that dealer rate of $8K and I asked him how much were they doing the job for, and I was told , a smigen less but not too shy from the $8.

Just wondering what parts / procedure is one on the 8K versus the weekend warrior 2,500 ....

Today - I took a car (N62) for both intake and exhaust valve stem seal replacement - Under $2000
I know - it sounds too good to be true - but All German Auto (Escondido,CA) claims they will soon have a tool kit available to the public (within a month or 2) that will allow you to replace your N62 valve stem seals without removing the cams/timing.
** I'll keep you posted **

That sounds awesome, could you keep us updated.....

Well boys & girls - the price of replacing valve stem seals on a N62 is about to take a nose dive. I just witnessed a tech using AGAs new tool - I wish I was half as smart as Martin (the owner).

Well keep us updated A B.

8K wow that's insane....

I am having my heads redone right now by Sheldon @ Autohead Performance

For $350 a head

This includes:
A thorough chemical cleaning, resurfacing the gasket face of the head, cutting the valve seats with the renowned 3-angle valve job, installing new valve stem seals, cutting valves to ensure optimum valve sitting, precision polishing both intake and exhaust valves (a procedure only we perform), pressure testing, vacuum testing the ports to ensure seats are sealed and double checking to ensure everything is within BMW specs.

Of course this is the price for just the head work no R&R and gaskets ect. But for those tearing down the top of the engine to the heads themselves this an excellent option.

Please keep us updated on the tool!!

Are they one piece seals or have they designed coupled halves?

Same seals (OEM) as if you were doing the job the hard way.
Note;
Updated seals are red in color
Old style (brown/black)

Damn I paid approx $5700 to have mine replaced a couple of months back that included sending the head to the machine shop.

Any idea what the cost would be for 4.6 heads?

Awesome, can I ask do they remove the springs? If so is that a separate tool or does the one tool (set) do everything. I have a mechanical engineering brain and I can't think of any way that this is feasible so absolute kudos to them and I'm very excited to see this tool in action.

Yes, the springs are removed - All the same tool set. When you see it you'll wonder why you didn't think of it.

:beerchug:

I'm pretty sure he could do the 4.6l heads for 350 each as well.

If u call for a quote tell him ur buds W/ Alex from MN

Thanks.

Any updates for the kit?

I'm assuming you mean the tool kit? It's only been a week, they need a month or so for tooling.

I saw his video (in amazing low-def 240p!) online. I had heard of using a leak down tester to hold the valves in place while you remove the valve springs, etc. as a quick way to change out valve springs from some racers. Never thought of it for this application but it makes sense. Very clever.

Still a whole lotta parts gotta come out to get access to the valves! For me, I'm likely to just drive down to Escondido, drop the X5 off and spend the day with friends! Better way to spend the day for me! :thumbup:

You may have watched a video from another shop here in town. I don't think AGA (All German Auto) has released their video yet. The other shop with the "amazing low-def 240p" is probably Escondido German Auto (E.G.A).

I think you are correct. My error.

Regardless, creative solutions to otherwise debilitatingly expensive issues are nice to see!

I hope it is more than just that. I have seen this method performed many times. You need to make sure you get your valves to the closed position. Then there is a tool specifically made to remove and install the valve stem locks.

While the air is being pumped into the cylinder, you whack the locks with said tool, and you got the locks off. Remove, replace seals and move on.

This.
Motion Pro Valve Core Remover - Dirt Bike Motocross - Motorcycle Superstore

And Leak down tester used to pump air in.

I hope A B has a cooler way to do this.

Dealership told me it's an 8K job as well. I contacted the master tech who does the job, he definitely knows his stuff. For 8k you might as well get a different engine installed. As of now I'm going through a an oil change jug a month until I get it done. I'll be replacing the cats after the job when the time comes around with some aftermarket "high flow" units. My X is running full steam ahead as of now, but I'm sure it can't be to healthy for it to be blowing that much oil out the exhaust.

Allen, will they have a detailed guide printed (or memory stick) with the tool? If not, maybe you can suggest that.

Thx!!!

I honestly don't think I could suggest anything to Martin from AGA that he already hasn't thought of - he's a smart guy.

Just to keep you interested - two more tidpits of information about the tools and process.

- A failsafe in the event you drop a keeper
- A tool that facilitates the installation of keepers in a matter of seconds

Looking forward to it :thumb up:

The only thing that would make it better if it could be done from on the couch with a cold one...

Impressive!

Well that look interesting. I don't understand how it works, But waiting to see.

So, my E53 is at the dealer waiting for the guy from the extended warranty company to come and approve the valve stem job. Is this a common thing? It's been there since Tuesday and no one has turned up yet. I thought the valve stem replacement was a pretty common thing on this car. Why would there need to be an inspection from the warrantor? Anyone else ever have a battle with a warranty company?

Luckily they gave me a brand new 528i to drive around in!

Not sure what the quote $$ amount was, but yes the warranty company will want to investigate. They will probably do or say whatever it takes to get out of this repair. They're not in the business to loose money.

Just noticed you said it's at the dealer - maybe you'll be ok.

Still haven't heard. I'm getting used to the 528i! Too bad it's white.

I'm betting it will take quite a while before it's approved for dealership use. The local shops will get it first. The dealers will want it vetted.

If there's a waiting list, I'm on it. Chalk me on.

You need to call them & they will contact you when it's ready.

If anyone in the charlotte/Asheville area gets it, can i borrow it??

I think we all have the same idea - why buy something for $700 that you're only ever going to need once...

As cool as this tool will be I can't justify spending that much on it for a one time use

Have you gotten a quote for this repair? If so you know that $700 is a cheap solution and you can sell the kit when you're done. I am on the list.

No but I would do the repair myself just would take much longer because I'd need to remove all the timing components...

Maybe I could look at buying it and selling it after...

If you're a DIYer - the cost of the tool is almost as much as purchasing the timing tools and a valve spring compressor for this job. If you're a BMW tech, this tool would be a must have. You could also start a online rental for your area, then it would pay for itself twofold.

I think it's much cheaper to buy that tool and the seals, plus the other gaskets that will have to be changed when doing the job, than having it repaired even by the cheapest indy. Besides, you'll have the peace of mind of a well done job. I am sure one can sell it afterwards, if not needed anymore.

The new OEM valve stem seals, are they updated so they won't fail again? Because if they will fail again, one might as well hang on to that tool.

I'd like to think that I am a DIY-er but I am scared thinking about the "juicy" parts of the car... like anything with the coolant, power steering, tranny, engine oil... so, it would be a serious learning curve even with the proper tools...
someone in the area with the tool and knowledge can do this as a side job, still recover the cost of the tool and hopefully make a buck or two...

for me, it is not just the $700 for the tool, even if i had the tool already in my hands, i'd be sweating bullets just thinking about the open heart surgery on the engine, regardless if it is a "full-blown" surgery or a little "incision" surgery...

so, I hope that somebody in the area who knows their sh!t, will get the tool and offer their services...

So the tool makes it so that less things need to be removed. Nice. It makes sense that this would make the job easier and take less time. Any idea on the time difference between this tool/process vs the old way? Days? Hours? Weeks?

I should also say that I have ZERO idea what kind of time the current/non-tool method requires. I'm just curious and a little excited about the idea that it can really help professionals as well.

I've never done the job - but having witnessed a few, I'd say 1 day vs 2 days.
It looks like the X's have much more room to work then the 5s or 7s

TerminatorX5 - you're funny:rofl:

I'm on the list.
They said it's 3 weeks now.

Question: the valve seal kit according to realoem has p/n 11340029751.
Are these the same as the original ones, or are these a different batch (improved)?

Thanks Alan!!!!!

Martin from AGA pointed out "improvements" on a red colored valve stem seal. I did not have a new brown/black seal - we compared it to an old seal being pulled off an engine. I'd try to stick with red in color seals.

That is the part number on my invoice.

Well - finally got the car back from the dealer. The warranty paid in full! The car has much better acceleration now and I suspect I will see an improvement in fuel economy. $5921 total. My share was $775 for replacement of the vacuum pump an new plugs and wires.

I had a loaded 528i as a loaner for the first week, but that car sold. My replacement was a 2013 E70 X5 3.5. If that had been the first X5 I had seen I would not have bought one. Holy jeez, what a hunk of junk! Uncomfortable seats. Shoddy interior. Questionable suspension. No thanks.

The service guy was very interested in the new tool.

You made out OK, but a few questions;
How did you get a 2006 covered under warranty???
Vacuum pump had a recall - why not warrantied???
Plugs would have been pulled for valve stem seals - should be parts only.
What wires on a 4.4 - you have coil packs???

I bought an aftermarket warranty when I bought the car. It has easily paid for itself!

Didn't know about the vacuum pump recall. I'll check with the dealer. Thanks for the heads up.

Plugs were parts only. I just said wires out of habit.

I have an after market warranty as well and im hoping this valve stem issue and a transmission kicks out while under it.

Today i learned theres a way toi do it witghout that took or taking cams out...
My BMW tech friend told me about it and hes seen it done.

Cylinder at TDC
Put shop air in the spart plug hole and KEEP IT THERE pumped so the valve closes then you can do the seals

which warranty did you have and what type of level did you purchase?>:wow::wow:

It's Vehicle One Major coverage

My tool kit is on it's way. I think I will change the cooling pipe as well, because during these cold days, I started to loose coolant in the expansion tank as well. No drips, no tell-tale signs, white residues, anything at all, but just loss of coolant in the expansion tank. Did some research and it seems these are the first signs the sealing O-ring on the OEM cooling pipe is giving it's ghost......
So I guess I have a big project on my hands this coming spring/summer.

I think the new style valve stem seal - updated version not allowing the oil to pool inside the seal should make a big difference. After thinking about AGAs description of the improvements, it makes perfect sense on why the old seal style allowed so much oil consumption. The top of the valve guide was constantly submerged in a puddle of oil. The new style has removed that cavity, so even as the new seal wears, the oil will naturally want to expel to the outside of the seal. So the moral of this story is, be sure when you replace your seals you have purchased the new style (red in color).

Martin pointed out to use the new style valve guides (red). I'm not sure if you can even buy the old style anymore (which I wouldn't do). Which would mean BMW acknowledged the issue, but choose NOT to address the situation free of charge for the poor design...same as that bloody cooling pipe......

Watched the demo and DIY video. Great tool! I certainly would purchase one if/when I need to do the job.

you don't need it for yours. If you buy an X5 with the N62, you might need it.

Isn't the 4.6 the older N62 with less horse power?????

I've seen the old style valve stem seals (at least pictured) for sale on the internet - the new & old style have the same part number - this is just a word of warning - if purchasing valve stem seals from a source other then the dealer, beware that you are not purchasing someones old stock.

M62.

wow nice tool

That's right - The N62 is 4.4 (325 hp) and the N62TU is 4.8 (360 hp)

You're right. I should get that permanently in the memory bank.

I always refer to my engine as a 4.6, don't relate to the M62 designation.

I don't know about others but I read so much about the smoking problem and other problems like those involving transmissions etc. I get to the point that I have to remind myself that not all of the problems I read about are going to happen to me.

I still think the tool is great and a justifiable tool purchase--------------for those with N62 engines, of course.

so, is there a consensus on this tool? where do we stand on this - the tool is being shipped - has anyone already used it and if so, how are the results?

obviously, there is a tool kit - is there a list of the parts needed for this job? the necessary parts for the valve job, and maybe a list of parts for other, optional (or, maybe not so optional) jobs, like that pipe that is buried somewhere deep in the engine...

if i am not an engine DIY type of a guy, is there a possible rental option of the tool? how much time should be expected to be spent on this job (based on time and labor rates, one can estimate the labor cost)?

AGA tool
 

Here is a link to a thread from a guy that has used the tool.

AGA valve seal tool - Bimmerfest - BMW Forums

that's what she said.....:nanana:

why not to replace the engine? I have valve stem issue on my 2006 x5 4.4, smog coming out from the pipe. I am thinking to have the entire engine to replace with remanufacture/rebuild engine. The cost may be cheaper with a rebuilt engine. I see some other posts on this subject. I am investigating right now.

^Because the engine is perfectly fine as long as there is nothing else wrong with it and once the valve stem seals are done they are fixed for a very long time

This.

If/when my seals go, I'm getting them fixed without a second thought. It's already 12 years old and has 78k miles without a problem. They could go tomorrow and I'd have no problem waiting another 12 years and running it up to 160k. Surely by that time an F15 M will be hiding in some garage with 10k miles on it. I guess I'd better get started on my search. :D

^I feel the same. Who would want to R&R an engine when you have an engine that you know well and maintain it, just for something that will last another 12+ years or more or possibly never be an issue again?

That reminds me, I have to start saving for a subsequent 3-pedal performance Bimmer for the future, since I know they will be in shorter and shorter supply as time goes on.

I subscribe to the devil you know is better than the devil you don't.

ESS supercharge the X5. :nanana:

When I was deciding where to go to twin turbos or supercharger I found that the only way to do either was a custom build. There is nothing off the shelf including from ESS.

Actually, there is. I emailed them a few weeks ago. Just to inquire about possible options. They said that the TS1 system for the E46 was compatible. M54B30 Twin Screw Stage 1 (TS1) - ESS Tuning If you scroll down, under intended applications, it says E53 X5 3.0

^^Not off the shelf for 4.6iS dude - for the M54 yes you're correct ESS is basically bolt on.

I'm dying to know if the TS for the 650 and 550 will work on a 4.8is. I know, I know, it's not listed. But you just know they'd do it if we asked. :cool:

Right? !ouch:

No one was interested when I was searching. I found sources that would do a custom supercharger setup but the benefit was not worth the cost. Same was true of twin turbos. IMO, meth injection and nitrous is by far the best route even when there is an off the shelf supercharger or turbo kit.
