Rod bearing noise is very consistent. and I've never heard it sound like a ticking noise either.
What about an exhaust leak upstream of the turbos? That can easily cause a ticking noise when the engine is under load. Even an EGR gasket leaking a bit....

hmm I think it really could be an exhaust leak, it does sound like that pop that a car running open headers would have. Also... when I did the screwdriver thing I didnt have a long enough screwdriver to check the rear valve cover but I noticed I might have an exhaust leak somewhere in the rear. I just installed td05 headers wastegates & e16gs about a month or so ago which also makes it a likely culpirit. Thank god, I'm so relieved. I was allready thinking about buying plastiguage and whatnot.
So a few questions...
what could have caused it? over torquing? Is it possible its just a under torqued bolt or 2? If it is would that have damaged the gasket? what if its a cracked header?
I know I should go investigate myself instead of asking on the forum. I'm just sooooo sick of working on this damn thing I'd like to get in and out fast...hehe. I just did the 120k and fixed a rear main seal; on top of spending too much time on the turbos b/c I stripped 2 threads. And I still have to do my VSS, and fix a bad TO bearing.
