Time for some work...

[weiln12]

All,

OK, looks like my CCV failed. I thought I had a failed pulley, and engine failsafe prog, and no power and all that stuff. So, time to do some work! I am going to do a compression test to make sure I didn't do any significant internal damage, hopefully that turns out well.

I'm going to be replacing the CCV system, hoses, valve cover gaskets, valley pan gasket, the whole works. I'm looking to make sure I don't miss anything.

I'm attaching some pics of the intake, and it definitely looks like there is a lot of oil in there and that's bad...

If you are doing the valley pan, the water pump has to come off. Unless they were done recently, I would replace that and the thermostat, along with the two pipes that go from the water pump to the back of the engine ( the ends were corroded on mine).

Welcome to the hell that is the M62 crankcase vent system.

Ripped the whole front of the motor off in my E39 this summer to do all that fun stuff.

Do your Vanos sprockets. Do them.

DrVanos.com Chris is awesome - and for $250/pc you're getting quality units. Unless you want to tackle the besian seals yourself.

@David - Yes, I'm planning on replacing everything related to cooling/heating. All the hoses, thermostat, pump, the whole works. I don't know the state of things, so I'm just going to do it all and be done. I think you mentioned a cold weather CCV system, so I will look into that too.

@TECN1K - I didn't think about the VANOS, but yeah, I'll add that to the list too. I've heard other use DrVanos, so I'll probably do the same. Besian seals don't sound like fun.

Also, first piece started and half done. Cleaned up the passenger side headlight using the 3M kit. Attached are before/after pics.

All,

So I've put together a list of stuff from ECS Tuning. I know some of it's overkill like the valley pan gasket set, but since I want to replace the water pump and everything anyway I'm willing to get it.

My concerns are...what am I missing? I won't know if I need to do the timing chain stuff until I can take the covers off and look at them. If I need to do them, then I'll order the kit to do the timing chain guides.

I also am not sure what I'll need to do the intake manifold and get it cleaned up since it's soaked in oil. I'm guessing the CCV and VPG kit will take care of this, or is there something I'm missing?

Nathan how many miles on are on your X5? If over the 100k mark then its good assurance to do the guides and be done with it. Doing the Besian seals is not difficult. If you just watch the provided video you can save yourself a few dollars on the Vanos units by rebuilding them yourself. My brother and a I have done 4 sets to date on our customers vehicles. Not difficult at all.

@Jay - Yeah, mine's a bit over and currently sits at a few miles short of 144K. I was going to wait since I just don't know the state of them, or if they've been done before. I'm guessing not since I don't get the impression the PO's had any idea about this vehicle. You mentioned the seals aren't that bad and a video...do you have a source for that video?

@TECN1K - That's perfect, thank you!

Now I just need to find some videos to know what I'm going to be doing. The timing chains freak me out a bit only because I've never touched timing chains before. It's about the one thing I've never done. All the rest should be straightforward.

[TECN1K]

When I did mine - the guides looked fine. I changed them anyway. Once off, I pinched the plastic guide channels with my fingers, and they shattered like brittle candy. Same thing with my OSV. BMW - whatsamattu with this junk.

Scary stuff.
