+1 on the Besian System write up--can't ask for better in a how too---
while your at it and if you have the double Vanos system you should change those seals out at the same time--you'll never look back--makes a big difference in how the car runs.

Why would replacing the valve cover gaskets increase performance? Not saying it doesn't, I'm just wondering.....
Naturally you shouldn't see any performance increases just from replacing your VCG, unless it was cracked so bad that it was spewing oil everywhere and your pressure was really bad, but even if that was the case, you wouln't be able to drive your car. The smell of burning oil would be freaking horrific.

It didn't make any sense to me that it would, I was simply replying to post #5 in an intentionally non-confrontational manner.

The only way the valve cover gasket might make a diff-is if there was a vacuum leak
causing the engine to labor--enogh air can enter thru a bad gasket and cause such
I hope he only had the single Vanos and because of such didn't take it upon himself to
change the seals out---what a big big waste of time if he had the double and didn't add the extra hour to change out the Vanos seals.

Sorry, I should have made myself clear, I was completely agreeing with you, replacing a VCG should not give a "performance increase". More of a "Wow this is fixed, my car runs better". Well like we all know, after washing and waxing our rides, sucker drives smooooooth.

He has a single, and I agree Poolman, but I guess single vanos don't apply..........why are we wasting our time. Those silly vanos seals.
