Recommended Posts

Hello Folks,

I need some advise from you guys? My car 93 Deville Touring Sedan, recently I noticed some knocking or clunking noice coming out from engine.

It's got 153 K' mileage, what might be this kind of noice?

Do I have to take it t the dealership or? Can you please, advise me on this matter.

Thanks for everybody.

Azik. :o

Sounds like you might be hearing "main bearing thump". Annoying but harmless. Do a search for it in the archives. lots of info about it. Pay attention to posts by Bbobynski (GM engineer).

This is your second post on this subject, I responded to it in your first post here:


Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home. Once you know where the Northstar is you can point your ship in the right direction to get home. So the star became a symbol for finding ones way home or more symbolically even finding ones path in life.
