Okay I get the VE-T running but it runs rich and fouls plugs out. I get different plugs. The car seems to run good. Then I come back to my shop and the car sounds different at idle. Like a knocking noise coming from the top of the engine, but a knock. Not a valve noise this was something different. like loud piston slap coming from the top of the engine but like a knock.
I did a cylinder drop test to drop a cylinder to isolate the knock. No matter which cylinder was down it makes the noise. I have 60psi oil pressure at 1200 rpm cold idle, car was misfiring.
I pull the oil pans and girdle. The bearings look fine, a few small pieces of dirt but nothing serious. The rod bearings look fine. There are metal chunks in my oil pan that look like they are from a cast piece, not aluminum.
The crank surfaces are all smooth. So I look to the top of the engine where the noise was heard. The cam teeth are worn on the gear and the keyway is bent all to hell. The chain looks to have chewed up the gear from being misaligned. The chain looks fine. But the gears are loose. Both of them. Very loose. I tightened them down to the factory spec of 116ft lbs.
Now I am just hoping I can throw the thing together and do a compression test. I just pray I have not bent any valves. I guess this could throw out the cam timing and cause the car to run badly right? Something so amateur I should have double checked the torque on that but somehow in the engine build it got overlooked.
If that cam gear is loose that may have been the knocking noise I heard. It would explain why a cylinder drop didn't change the noise, and would explain why all the bearings are fine. Any input? Does anyone think I would have bent the valves?
