I've been working on replacing my head for the better part of two months, now. Between school and work, I have almost no time.
Well, I got the head back on and everything bolted back up. I fretted over the belt a lot. The DOHC locking tool saved my sanity.
I checked, double checked, triple checked the marking on the camshaft gears and on the crank.
I started it back up and I'm getting a knocking sound from the engine. It's nothing crazy like when the belt went out, and the engine isn't vibrating and jumping like crazy.
First of all, please tell me I didn't jack up this new head.
I tested compression and I'm getting ~105psi on cylinders 1 - 3, and ~90 on 4.
Is it possible the sound is due to the head not being fully lubricated? It was brand new if that makes a difference.
Is it possible that I'm 1 tooth off on the crankshafts? If so, again, please tell me I didn't jack anything up.
Any other thoughts?
