It's been that way since I got it in feb. I can't seem to find the leak anywhere..

Same issue with my car, I was told it was my PS pump. Idle is rock solid thought and I idle at -22hg with a 99 lowport. I was told our motors idle at -19hg

Wow. I'd kill for that low of vacuum. Mine hovers around -15 with no leaks. I blame the big turbo.

hah I have a lifter tick as well... Heh.

Yeah that's pretty much exactly how mine sounds... I just hope I don't have to replace it and it's just a simple fix =\

I replaced so many hoses... I know it has to be something stupid and simple... If I figure out what mine is I'll tell you and I'll appreciate if you could tell me if you figure yours out
