I had the EXACT same leak after my VCG install. I'll tell you how to fix it.

I followed both the Besians instructions and the Bentley manual. That is how I found out that Besians listed a slightly lower torque value for the front of the Vanos cover than the Bentley manual did. This lower value is what caused my leak. When I retourqed it all to the slightly higher value, it stopped leaking.

I would advise you to do it all again, use RTV, clean it all well, since it will have oil all over the place, and use the torque specs from the Bentley manual.

EDIT: I've pointed this out before, and no one seems to pay attention. I'm guessing that not everyone has problems with the lower specs he gives, or they over torque from the lower value so and are just lucky.

He needs a new valve cover.

I already had experience with VCG when I replaced the 530i using the red. Had to do this twice before I finally concentrated on the exhaust manifold perimeter. Figuring that since it sits lower than the instake. And also around the front and rear of the half moons. No leaks....finally. But continuing to monitor.

However, on the E46, I decided to do the VCG, VANOS, DISA, OFHG and the CCV hoses. I did this with a BMW tech. But when I started to use my red sealant, he had another sealant that they use at the dealer. It is blue and after application, it feels like liquid candle wax. I will have to get back to him on this type of sealant and ask him about it.

Was it Drei Bond? That's what TIS specifies.

I dunno. It was a white tube with BMW brand on it......I was not concentrating on that situation at that time. We were just plugging along to get the project done as soon as we can.......We were just glad we got it done in a day.....late.

I missed your previous post.

That could be true, but it seems unlikely. Should be pretty tough to warp those things. He should be able to check whether it's warped or not with a straight-edge, if you've got some carpenters tools. ASSuming that it is not warped, go with the torque specs out of the Bentley manual.

A follow-up on the sealant used. "Permatex Hylomar Universal Blue Racing Formula Gasket Dressing & Flange Sealant". Do NOT use any other cheap Hylomar that can be purchased in Harbor Freight (made in China)

Permatex ultrablack is top-of-the-line for Permatex. Make sure that stuff your friend used is oxygen sensor safe.

As far as a valve cover being warped being unlikely, as I said, mine was warped and visibly so. Brand new Genuine BMW valve cover and brand new Genuine BMW valve cover gasket and permatex ultrablack, no more reoccurring leaks for me. All is bone dry.

And my valve cover is warped visibly as well as with a straight edged. The front corner is what warps. It tends to lift upwards.

Aaaand mine was visibly leaking at the front corner, too. Not the half moons side, but the passenger side, at the corner that "points" to the passenger headlight. This point was visibly leaking, the rest of the passenger side VC was wet to touch. If this all is correct, I have warped VCG, too. But Permatex BLACK along the whole perimeter of the VC was enough to fix it. I'm just sayin', I am not recommending...

Oh, and those bolts are probably the simplest bolts to tighten on the whole car - just follow the rule: when they stop, you stop.

Yep the corners are where it leaks. The VCG bolts are not bottomed out at the factory.

We like to think we are a little better than the fellas at the factory

If all this doesn't work, check your CCV. Pressure regulator valve might be crudded up.

Very possible scenario, especially in colder climates. Though you could just pop your oil cap to see if theres suction as the engines running.

That is exactly what the BMW Master Tech mentioned. CCV really do tend to fail more in cold climes. That was why BMW produced a hose with insulation and made it bigger. But it wouldn't hurt to replace the CCV hoses once since they are still original parts even on warmer climes. Good thing I did. I think one of the POs had varmint infestation. The insulation was used as their snack...... LOL.

guess what the fix was? new valve cover. old one was visibly warped. I'm going to do a post on this soon with pictures.. haven't had time
You know, normally I would be be wishing to avoid replacing the cover since its $200+. But I don't give a #$%^ anymore! I will go an carefully inspect my cover, and if I notice anything ( which I honestly hope I do now) I will replace that sucker in a heartbeat!)

Oh it's warped, leaking fairly heavily around that point, & I can push on the cover & get it to move.
