4.6 l knocking sound? why?
 

Hello

Please help, there is still knocking sound coming from the engine 4.6 Cadillac 1993

You can't hear it when the engine is cold, but when it is hot then it starts!! that sound comes inside the engine, looking from back, from right sight,

If I take belt away you can't hear it well, but when you install belt back it starts and you can hear it clearly :mad::mad:

When I give more RPM it seems to disappear..

I have got very many good advice, and, so
I have changed: belt tensioner (all), a/c compressor, balance harmoniser and power steering pump... I have not changed alternator..


Could it be problem in chain or....????????

PLEASE HELP how to get rid of that?!:)

I don't wanna loose my cadillac!!
