Sort of an update. I really don't have time for this car anymore so I'm most likely putting it for sale but....
I did a leakdown test by setting it to 0 then plugging it in (which is 100 psi instant into the cylinder). Well it needed convincing to get the piston perfect so it would not leak out the valves. Testing cyl 2.
As I did this and with the crank not trying to spin I was reading 15% leakage. If I rotated the crank a bit (force on the bar so it would not rotate back) It came down to about 3-5% which is fine for me. I even did this for cyl 5 which read basically the same thing. So there are 2 ways to do this test which I do not like. The set and plug in way. Or rotate until resistance, crank pressure and hold bar.
Even with my buddies csrt4 I did it by rotating the crank until there was resistance/cranked the pressure up and held the bar. He had 20% on all 4. Ripped the head off and hairline cracks on every cylinder.
Plus this is a regal and an auto. I see stick cars being tested on youtube and set the ebrake and put in gear so it has no way to rotate at all unlike an auto could unless you hold the crank.
I think I can rule out rings hopefully. But how in the hell is the spark plug wet up the threads?????? Everything is bone dry on the head and was on assembly. I was looking on my original motor and thinking how in the hell is this possible? I can clearly see the exhaust valve but the intake I cannot. If something on the intake side is doing this I cannot see until ****s apart. Possible it could be. Bad intake gasket seal is really the only other cause if the rings are mint unless there is something wrong with the valve guide seal. Or a cracked head but its iron so that's not very possible.
