I was on vacation last week and got home last night. While in the states I went ahead and got new gaskets at the local MB dealer. $20 sound alright? Today I took the upper manifolds off and the drivers side was wet with gas all over. The passenger side was dry. So as you can imagine, no scraping off gasket material on one side and lots of careful scraping on the other. It really wasn't too bad, just real hot work. Naturally after getting it together I wanted to go for a ride but beach traffic kept me home until the sun started going down. (poor me!) Anyway, I just got back from a long test drive and the gaskets did the trick. I found putting the adhesive on the manifold side of the gasket and sticking it to the underside easier than on the runner itself. I used Locktite Blue on the threads this time to prevent a repeat of the problem. It seems a P0505 is a boost leak. Thanks again for all the good advice.
