Hey every one, i did a quick search and couldnt find what i was looking for. I have a knocking noise from what sounds like the left bank. It happenes when i start the car for the first time in the morning. It sounds like a bottom end knock but if goes away when the engine is hot.
Has anyone had the same problem or can any one shed some light on the problem??

Thanks Matt

Is it a built motor?

Could be piston slap.

how many kms on the motor? my old GC8 had a bit of a knock in the bottom end, it was fairly old motor...as far as i know its still running.

my RA on the other hand had a very loud dok dok when it spun a big end bearing it is no longer running!

It's just piston slap if it disappears after a couple of minutes.
