Amen to that, that sinking feeling stinks! You start creeping toward 100k and you know itís coming... but youíre still never really ready to do them.

Amen. I've been putting parts together for a long time. Last piece of the puzzle is the Xover pipe. Can't decide between pulling the timing covers and doing an OEM style pipe (with updated seal) or doing one of the expandable type pipes. Pulling the covers adds 10x the work (including pulling the front axles from what I have read) but is the way I'm leaning... because why do things the easy way? :confused:

Good luck with yours. I'll be following. Until then I'll keep dumping the "secret sauce" into the crank case to stave away the 007 smokescreen on extended idle.

Did you also have the sinking feeling in the pit of your wallet? Ö.:D

We all do. I plan on tackling it myself if no one pops out and does it for like $1k tops. Other than that, not really worth it to not try and DIY.

Thatís exactly where Iím at. Iíve been wrenching on this thing since I bought it so I figure why stop now.. not to mention I have a handful of other things I want to tackle while Iím under the hood anyway.

It's not a tough job really. If you're comfortable tackling the valve cover gaskets, valve stem seals replacement is very much within your skill level. It's just time consuming and requires super extra care. One must not have time pressure when tackling the project. I strongly advice against renting the tools. You'll be under so much pressure to be done and that's just the right formulae for serious errors. I did rent from Tonys Aga N62 Tool Rental service and lost $500 since I wasn't done when return date was due. I then bought my own tools (including the timing tools!) for around the same amount (duh!) and took my sweet time to carefully and slowly complete the project - about 3 hours a day in the evenings after work and 6 hours a day on weekends whenever the lady of house allowed. Took me about 2.5 months. Only rent if you can dedicate at least 10 hours a day for 2 weeks. Imagine if you had to re-open the engine if things were not right upon reassembly and a test drive. You have to provide time for that too.

Good luck!

"because why do things the easy way? :confused:" - Ain't that the truth!


"secret sauce" - Oh lordie, share with a brother :excited:, I'm keeping an eye on the oil level but still (embarrassedly) driving the smoker... I did bump to 10w40 and tried Restore, seemed to work for a little while... maybe a year and then was back just like that!)






I feel like I try to be as preventative as I can for the most part, not throw money at it per say but when my water pump died I did the entire cooling system refresh and two new belts, or my bushings crapped and I found a little bit of play in 1 lower arm, I did the entire front suspension, etc..



(I did take a shortcut with my water pump job in repairing the xover pipe, I had no visible, or other, indication that I had any issue with the xover pipe so I just did a lot of sanding to keep the fit as tight as possible and did an aluminum stint pipe. Not sure good or bad idea, but so far no issues.)


Trying to plan for the future since I figure I'll recover my investment by keeping the truck and not having to do "that" job again for a long time. So when something does pop up on me I try to be as complete as I should be.


That said, while I have this apart, what do I just clean up and make sure is ok vs just replace or fix while I'm this close to it now??


Just found this list:
Throttle body O-ring p/n 13547510433 (x1)
Right upper timing case seal p/n 11147506424 (x1)
Left upper timing case seal p/n 11147506425 (x1)
Solenoid big O-ring p/n 11367513222 (x4)
Solenoid small O-ring p/n 11367546379 (x4)
Vacuum pump O-ring p/n 11667509080 (x1)
Valve cover seal right p/n 11127513194 (x1)
Valve cover seal left p/n 11127513195 (x1)
Repair kit valve stem seal p/n 11340029751 (x2)
Eccentric shaft sensor seal p/n 11127518420 (x2)
Camshaft positioning sensor O-ring p/n 12141748398 (x4)
Valvetronic O-ring p/n 07119903596 (x2)
Optional:
Valvetronic spacer torx bolt p/n07129900465 (x2)


And any opinions on Corteco, Elring, OE or other stem seals and components?

Purplefade 04-12-2019 11:37 PM

Oh and while I am thinking of it, I am going to do my upper timing cover gaskets, should have done them with my water pump and vanos... but I didn't :dunno:


Is it my understanding that the N62s don't really have an issue with the timing chain guides?? Or am I confused??

SlickGT1 04-13-2019 12:29 AM

Timing chain issue was m62. N62 pretty reliable on that front.
