Won't start after cam install

**Bedwards** · 06-24-2011

Who knows... Maybe the whole harmonic balancer/crank key thing messed up the position of the crank sprocket. However, after removing the sprockets, I inspected them, and made sure the keyways were in good shape. Me and my dad re-assembled it, and made SURE the keys lined up. From what I see from turning the motor over, and watching the lifters and firing order, the engine is timed right.

The balancer can't change the timing. That chain is the one and only thing that controls what happens to valve movement. That's what has me stumped

I don't remember, but when the harmonic balancer was on wrong, did the key come off the crank sprocket? So the cam didn't turn and the valves stayed in position so the pistons made contact? Like Bill said, pull the heads, or at least use an inspection camera of sorts through the spark plug hole.

No the key stayed in the sprocket, from what I saw. I'll look at my car tonight. Going home in 20 minutes.

Pulled the head with the most pushrod damage...

I knew it. The valves DID NOT touch the pistons. It was timed properly the entire time. This proves that having your balancer on incorrectly (awful ignition timing) can damage your pushrods.
