He did a leak down on the rest of the cylinders, all of them are basically 2% like #3. So cylinders are solid. Which makes me feel much better.
He scoped #3 intake valves and they are wet with oil. Next is taking valve cover off and going in for valve seal surgery.
How do they do it? pressurize the chamber? or string into the chamber?
When i was having a similar issue with my first 4P head that Chet assembled, i was talking to the 4P afterwards and they were saying that some of their race heads dont use seals at all (but maybe he said it was only on exhaust side)

Seals are fine. Nothing visibly wrong after that. Guess it's time to take the head off.*
Wondering if something got damaged with the head in this cylinder from shrapnel before that the machine shop didn't catch.
I hate this car.
^ what are you chasing? blown head gasket you think?
compression is good, leak down is good. seals are "good". I think you would pressurize the coolant jacket way before you would have coolant going into cylinders.

Oil in cylinder #3 is what we are chasing.Originally Posted by mityaz
I'm setting myself up emotionally to probably put the car up for sale after figuring out this issue.
Ahh - bummer man...
So do you think you would back fill it with something else? or just go without?
Razor does the car smoke on deceleration, heavy vacuum?
@Black E No it never did that I noticed, mostly when I started creeping away from a stop or light and sometimes when going WOT
Here are both sets of seals while still installed. Only somewhat funkiness is the darker stuff on the top of the left exhaust seal.
Intake:
Exhaust
that mating surface on the exhaust cam cap looks dinged. or is it just the picture?
