Hello. I recently picked up an 88 GL-10 turbo for 300 bucks and have been tearing into it for a couple weeks now. Major issues were a cracked radiator, partially broken exhaust manifold and the infamous melted/shredded timing covers.
I removed the whole front end of the car and ditched the covers, noticing that the old (somewhat shredded up) timing belt had been riding over the inside edge of the driver's side cam sprocket by about 1-2mm.
After replacing the timing components and dialing in the timing, I noticed that the belt is STILL walking off toward the engine! Everything is in place properly (I've done this before and am totally sure of the procedure) and the belt looks bang on on all the other sprockets.
Is it possible that the head/cam was reassembled wrong? It looks like the head gaskets have been done (excess sealant in some places), so I'm wondering if someone monkeyed up the shaft?
Any help or related experience would be great, and thank you ahead of time.
