Ok team I am having some engine problems and struggling to diagnose the issue. All I can explain is the problem not how it happened as a mate had it when it happened...

So there is a serious rattle/knock coming from the engine at idle. Rev and it goes away.

I took all the plugs out and turned it over and it sounds perfect. Put 1 plug in any cylinder and there is a knock/rattle once per cycle. All plugs means more rattle.

Took the rover cover off and cam chain is fine. All valves look fine.

Rattle is only there when compression is there.

Im thinking not bearings because it is all cylinders and it happened all of a sudden.

Any suggestions on what to check?

Cheers

Ed

Mechanical. Occurs with only 1 plug in and no coils and at starter motor speed as a clunk once per cycle. Start it and it turns into a mechanical rattle. Thought maybe it was the whole engine/turbo rattling against engine bay at first but is defs engine related.

Umm 300rwkw has increased the power output by at least 50% so the chance you have gone from a 5 to a 6 is at least 80%
