This is a follow-up on the klatta-klatta noise that our C36 is making.
We've noticed that it only makes it during idle, and it sounds like its coming from the timing chain/cam sprocket area.
Via the diagnostic port, we can activate/de-activate the cam-advance solenoid.
When activated, the sound is gone.
When de-activated, the sound comes back.
Does the intake cam sprocket assembly get noisy, or could this be chain stretch?
Could this contribute to no high-end "umph"?
Our only testing is with the stock 300TE exhaust (single cat, single O2-sensor), so we are now fabricating a dual-cat and dual O2-sensor free-flow exhaust that will mimick the C36 exhaust system.
Any other ideas?
