I recently picked up my tentatively finished and freshly rebuilt 1990 talon tsi. I replaced every part of the recipricating mass with either oem or aftermarket parts (all new), starting from the Wiseco/Scat stroker kit down to all the accessories, water pump, all belts, pulleys, etc. Basically the only original part under the hood is the block, EVERYTHING else is new. With this said, I noticed the other day that there was some minor belt squeel coming from under the hood. It was cold out and the first start of the day so I figured it just neeeded to be tightened as none of the belts have been readjusted since the fresh build. The squeel was not very loud (more like a chirp) so I drove to work. After work when I started the car up again (2nd start of the day about 7 hours later) the squeel was unbearably loud (like everyone staring out of the office at me and my car, loud) but only for like 4-5 min then it went back to the quieter and less embarrassing "chirp". Sounds like an alternator problem/belt so i check all the usual stuff, turn the lights and defroster on and off (no additional squeel) and the belt seems tight. Now i'm stumped so I just start looking around the engine bay the next morning after start up (first start of the day again) and notice that my crank pulley/hamonic balancer is wobbley and moving in and out (towards and away from the block) looks like the signs of dampener separation but how could this be with a brand new but oem harmonic balancer. The other odd part is that when the car warms up the harmonic balancer stops moving in and out and is as straight as an arrow (no wobble at all). Please help! Does the new harmonic balancer have a "break in" period or something? Does the rubber in the pulley need to conform to the new motor? PLEASE HELP!
