After replacing the head (gasket, water pump, timing belt, tensioner belts) with a rebuilt head it would not start, cecked the belt, found it two notches off, I slacked the tensioner, reseated the belt, rolled the crank over. set the tensioner to torque, buttoned it up. It would not start. Belt had slipped again. This made no sense, Replaced the tensioner with a new new one. And found the first was bent, Bent? The rear plate was about 5 degrees off vertical, (Post A PICTURE)
New tensioner, car will not start. Checked fuel, injyctor relays, cleaned regina coil/stage, even the FI Grounds on the intake manifold.. Nothing.
Even though I Know the belt is fixed I set it to TDC, pry the cover open at the top and peek at the Belt .
It is about half off the cam sprocket/ and running off the tensioner.
I remove the cover (Waterpump pullry, P/S Pump tensioner) and the tensioner. It's a little bent..
I pull the mounting stud and it seems straight (rolls down the counter just fine). I put the tensioner on the counter and it's a little bent. Not as much as the first, but enough it wobbles on a flat surface...
How is this even possible, he fairly shrieked.
I will post some photos, you disbelievers.
1. How is this possible?
- could the mounting hole in the rebuilt head be rounded/keyholed/screwed?
- could I have bent the mounting stud when I used the FCP hold down tool to refit the harmonic balancer?
(It did not fit well.)
- when the tensioner is bolted down, isn't it flat against the head?
2. Where do I find a good tensioner (brand)? These were GMB
3. How far back should I go? All the way back to the crankshaft gear and sprockets?
