I have a '96 Subaru with the 2.2L engine that will not stay in time for more than a few minutes.
This started with a timing set replacement due to a catastrophic failure of one of the pulleys.
It seems now that the belt is slipping on the crankshaft pulley as best as I can tell. I say this because it seems that the cam shafts are still timed together, but the crankshaft pulley is in the wrong position.
I set it all up to spec, reassemble, and then test run the car. all is good for about 5 minutes, then a sudden loss of power and I find that the belt has jumped again. This has happened to me twice now. I do not think that this will happen at idle or if I throttle up with no load on the engine, but I just haven't reset it and re-tested enough times to be sure.
The tensioner seems to be OK. It takes a lot of pressure to collapse it again and the spring does drive forward into the tensioner pulley as it should.
Is there some step that I'm missing here?
TIA
