If what you say about the harm. bal. the sound that im hearing is the bearings, and this is causing the tensioner to jump the way it is. but yes, that is what my harmonic bal. looks like, ill get another one in a day or two, and replace it myself to save myself another 310.00. thanks guys
It'* very easy to replace. Took me and Bill 10 minutes tops the (final) time we changed mine. Air tools are PRICELESS with this job.
That pic is of a HB from a supercharged car...yours will of course have only one set of grooves.

Very true! When my HB went, Advance ordered the wrong part 3 times. Granted, 2 of those times they ordered an L27 HB, wrong engine. But then they ordered a 95 thinking it would work with my 94, and we slapped it on and I knew right away something wasn't right. Not balanced at all. I wondered what could be so different since the engines are the same in 94 and 95. But something was different alright.
When we finally got the right part, we looked at both to compare, and it was clear there were big differences in each, specifically the weights. The 95 was 3 times the size as the 94.
