Has anyone here encountered an issue with their harmonic balancer/crank pulley twisting?
I've had my P5 for about a year and a half as a beater. It has really needed some work. In the time I've had it, I've found that just about anything made out of rubber has gone to crap. Motor mounts and suspension bushings mainly. This past weekend, I decided to check on the timing belt since I had 184k on the clock and had no idea if it had ever been done, plus I've had bad engine vibration. It turned out my T-belt was fine, but the tensioner and spring were wasted, so I decided to do the whole kit- water pump and all. When installing, I put the #1 cyl at TDC on the compression stroke by removing the spark plug, turning the crank pulley bolt until by thumb is pushed out of the spark plug hole from the compression. From there a screwdriver down the hole gives me a visual on where TDC is. In looking around at the manual later, I see that the harmonic balancer has a yellow tick mark which SHOULD line up with the "T" marking on the timing case, which is at about 11:00 when looking at the pulley bolt. At TDC, that timing mark of mine was at 3:00. Way off! I visited the junkyard and found two Protgs which had the FS motor. One had no timing mark (wtf) while the other had the mark at 1:00, also off from where it should be. I'm guessing that the rubber inside of the Harmonic Balancer has rotted out (just like the rest of the rubber on this car) and allowed the whole thing to twist. Since these are supposed to be balanced, I'm guessing the twisting has thrown the balance off, causing my engine vibration. Has anyone encountered the same thing? It seems odd that the junkyard car had tick mark out of place like the one on my car, could this be a chronic issue?
