Last night I was driving home from a friends house when all of a sudden the exhaust and intake got really loud. I pushed the clutch in and the engine died on me. Turns out the rubber seal for the timing cover got caught in the belt and must’ve slipped the timing. However I cranked the engine over and it turned fine and kinda ran, but loud exhaust and intake like the valve timing was off so I killed it. Pushed it home as I was only a couple blocks away.
The next day I went to investigate and I found that the cam gear was off 1 tooth backwards, and the injector pump was off like 5 teeth. So I pulled the belt off, and replaced it with a new belt, lined everything up, hand turned it over fine. So I went to fire it up and there was lots of valve clatter and intake noise was a little loud. So I pulled the valve cover off and all of the clearances had like half a cm of clearance.
So I tightened all the valves to 0.25mm intake, 0.43mm exhaust, and it runs fine, but it’s a little slower and the EGTs are a couple hundred degrees hotter accelerating, blows a bit more black free revving so I’m thinking maybe timings off slightly or valve clearance isn’t perfect.
