What would cause chug/tick noise? (out of ideas!) Posted by Nathan [Email] (#2249) [Profile/Gallery] (more from Nathan) on Wed, 7 Sep 2005 09:56:15 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Hi All, perhaps somebody might give me an idea here!
Car: '01 95SE, 117777km
Symptom: Chug/Tick noise, frequency is proportional to engine speed. Amplitude is proportional to turbo boost. Not noticable at idle/low load. "sounds" like it's coming from lower left area, when sitting in drivers seat. (Canadian driver's side ;) )
Steps so far: Done a through exhaust inspection and cannot find any leaks. From the inside it sounds exactly like an exhaust leak... but can't find it.
Tried stepping on brake and gas, and since the noise doesn't really appear until 2500RPM, I don't want to blow my torque converter.
Also tried plugging tailpipe to increase backpressure... no noise.
Could it be a leak from the intercooler (charge air cooler)?
What else could it be?
Thanks for any help!
