OK, here is a dumb question-does the turbo, when spooled up and cranking positive pressure, pressurize the crankcase to the point that it will, let's say, 'encourage' oil leaks???
I have a 88 daytona shelby z, and made the mistake of trying to correct a problem it has always had-oil in the airbox- I took the valve cover off (first mistake) because a TSB said to change a nipple that feeds the airbox from the crankcase. The 'new' one was exactly like the old one, but gee, I waited a week to get it from the dealer, so what the heck, I removed the old one and installed it-couldn't make it worse, right?
Well, while at the dealer, I said, 'I need a new valve cover gasket' so he ordered it and I got it the next day-one piece...when i took the cover off, it was NOT one piece, but the dealer said this one was better, so ...mistake #2. I cleaned it up and 'installed' it, being careful to torque it evenly-all went well until I heard a sickening 'crack'-you know, I broke the cast 'turbo' valve cover...so I JB welded it, and it worked for a few days, but started to leak-I went on here and got another turbo valve cover (thanks tryingbe) but until I get it (end of the week) I figured I'd go to a junkyard and just get any 2.2-2.5 valve cover-got one off a 90 Daytona 2.5 normally aspirated, and it is one of those 2 piece deals-it had a sheetmetal cover that sits over top the rocker arms, then the stamped steel cover goes over the entire mess, hopefully sealing the thing until I get my cast piece from tryingbe-it takes a 4 piece gasket, cork for the long sides and rubber on the ends-i put it together, took it for a ride, and it LEAKS WORSE than the broken cast cover????
I took it off, looked at it, and put it back on-but didn't drive it this time-it seems OK, but when I drive it and 'boost' does that 'seek out' the flaws in the seals?
Third time is a charm, when I get my new cast cover...I hope:bang head:bang head:bang head:bang head:bang head:bang head:bang head:bang head
