Car Forum / Oldsmobile Cars / July 200791 Olds 98 Engine noise?
I have a 91 Olds 98 that has a engine noise on pulley side of engine, sounds like a clacking, when I raise the rpm the noise goes away, @ idle the noise is there. When I accelerate hard I get a loud crack then the clacking comes back. I thought I found the problem (belt tensioner), replaced tensioner did not get ride of noise. Car is not overheating,power steering is fine,alt puts out 13.2 volts,belt does not come off. Noise seems to be much louder when I listen down at the ground. Mileage 132000,3.8 V6 Any ideas of what to look for? Thanks Ross Run it for a few minutes without the belt, could be the timing chain or the crank balancer is coming apart, both common issues. >I have a 91 Olds 98 that has a engine noise on pulley side of engine, > sounds like a clacking, when I raise the rpm the noise goes away, @ [quoted text clipped - 11 lines] > Thanks > Ross > Run it for a few minutes without the belt, could be the timing chain or the > crank balancer is coming apart, both common issues.<rv4sal...@gmail.com> wrote in message [quoted text clipped - 19 lines] > ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==----http://www.newsfeeds.comThe #1 Newsgroup Service in the World! 120,000+ Newsgroups > ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- Thanks for the help I did find the noise it was the harmonic balancer that pulled apart Thanks again On May 31, 6:10 pm, rv4sal...@gmail.com wrote: > > Run it for a few minutes without the belt, could be the timing chain or the > > crank balancer is coming apart, both common issues.<rv4sal...@gmail.com> wrote in message [quoted text clipped - 24 lines] > > Thanks again What a coincidence. My harmonic balancer JUST went out on my 88 delta 88 royale. Except...mine was literally in a couple of pieces, held together only by the belt. You may want to check your spark plugs for damage...having the harmonic balancer go can throw off timing, and cause problems with the valves.
