I've run into a weird timing belt problem that I can't seem to resolve. Hoping that maybe someone here has run into this before and can shed some light on how to fix it.
I recently swapped out my turbo m20 for my 3.0l stroker. I got tired of bad gas mileage and an unreliable megasquirt. I got everything back in and running and all seemed well. I took it out, banged through a few gears and then headed back home for the night.
Then next morning I'm on my way to work and bang through a couple of gears getting on the freeway and I start hearing this HORRIBLE squealing noise. I eventually trace it back to the edge of the timing belt rubbing on the inside of the lower timing cover.
The timing covers were powdercoated on both the inside and outside. I intially though it was warped form the baking process or was a clearance issue, so I swapped it for a stock unpainted one. Reinstalled, all was fine until I banged through some gears again. Added a couple of washers behind the cover to add clearance, the problem again resurfaced. Added tension to the tensioner and losened it. Problem still exists.
At this point, I've gone through 3 timing belt tensioners, two timing belts, two sets of timing covers. The problem still resurfaces under hard acceleration. It seems like the belt keeps sliding forward like it's trying to come off the gears. I've had this engine in the car before and never had this issue. When I pulled it, the motor sat on an engine stand for about 2 years before going back in the car.
HELP?! I'm about to put a bullet in the motor at this point.
