Started looking, not finding, and haven't seen a discussion here for a while. What noises are from what? For instance, I want to say a worn wrist pin is noisy at idle, and maybe engine decel, but not above idle. Or something like that--which is the point of the thread. I think main bearings are a low thud which is always present... or might go away above idle if from low pressure...?
On a related question, what might be the noise on my car? I swear at times I have a knock or rattle, at light throttle, maybe during light accel too. Might be gone when hot. But not during decel nor under heavy throttle. Before you say preignition it is on my diesel.
