La318 cylinder head question
Ok, so turning everything by hand, it looks like the exhaust is closing exactly as the piston hits the top, and on compression, the intake isn’t fully closed until at least 20-30° past when the piston starts to come up. (A rough estimate using grease pencil marks on the balancer). Is that normal, or does that tell you the timing is way off?
There is a small mark on piston 6 as well. Just one tiny one, I didn’t pull that head as there was no ticking from that side, I thought it was drivers side only initially. The #3 exhaust valve has no visible damage, could there still be enough to drop compression that much, or is that explained by the intake valve closing late on compression stroke?
