Check this out, been trying to track this vac line leak for about 4 months now, but the one thing i didn't take off was the actual I/C pipe itself (never thought it would wear threw like this) it appears that it had been rubbing on a hose clamp screw head for a while now.

Replaced it with a new one and now no more vacuum leaks and crappy idlying!!

al ;)

I have got some irratic idles but unable to trace the leak. What is the I/C pipe and where can I find it to check?


Thanks

That particular intercooler pipe is the one that goes from the top of the intercooler into the throttle body, the hole i found was on the underside.

Good God look at the size of that hole! you must have been getting really bad mileage? how black are your spark plugs?

Could you not hear the sound of the leak in the engine bay?

I suspect i have small leak in my intercooler as well and that cant be repaired.

How good does your turbo feel now:cheesy:

Funny thing is it was running completely normal, the bolt head was so close to the pipe that it almost sealed it, but the A/F ratio was showing slightly rich under load.
