Hey guys, I have a (another) wierd one....

When the car is coold and first starts, engine is qiuetly puring along. However after ~10-15min's, when idleing I can hear a distinct knocking noise coming from what sounds like near the front left of the engine.

Under load it goes away, or at least I can't hear it.

Is my oil to thin as I used 10W-30 and while I don't know anything about oil, should I just use heavier oil? The car has 140K miles on it but compression is good and the timing belt and tensioners were just replaced.

Any ideas?

Thanks.

try two simple things, check you oil level and make sure you are buring the correct gasoline if that checks out get back to me
