7:03 - what psi do you use for leak down? 15:33 - where did yall get the black tomei timing belt? I’ve only seen the blue ones.

I know that Arp says to lube the washer on both sides,but this is wrong,it can cause the washer to spin Better to sand the bottom side of the washer with a 60 grit paper so it will bite and not turn

I had a some scoring on one of my cam journal and cam, bad enough that it can be felt with the skin of your finger. How repairable is that? Or does it require a new head.

with out seeing what the scoring looks like it is tough to say, some minor scoring can be smoothed out and be ok. id be more concerned with what debris caused the damage. if you have been able to removed all oil plugs to clean the head, the journal can be cleaned up with some light sanding.

@@boost.factory when I inspected it, I noticed the cam caps 3 and 6 were mixed up, and the last cam cap 7 wasn’t entirely bolted down. As a result, the cam was hard to turn, the timing belt jumped several teeth, and pistons hit the intake valves. Only the sixth cam cap journal sustained damage though. If I had to describe how the scratches felt, it’s not like a slight abrasion. You can feel the individual ridges. I don’t think it was caused by debris.
