My motor is making a loud noise, similar to a rod knock.
It only occurs when the engine is hot, and has just been driven.
The knock goes away after the car idles for a few minutes, and returns after the car has been driven again.
I have checked all the easy stuff:
Oil and coolant - clean
Plugs - clean
Data log - everything looks normal
Performance and driveability - great
All of the pullies are quiet and tight all though I have not gotten to those secondary accessory belts.
Any advice on what to do next? Is it time for a compression test?
I was going have a look under a valve cover but I don't really know what I would be looking for.
Car info: early 03 cobra, 36,000 mi, 2.8 pulley, LDC head cooling, a bunch of other mods that aren't relevant to this issue.
thanks
