So I replaced the valve stem seals and it looks to be a complete success -- No oil usage right now.
Due to the fact I had compressed air already there I did a leakdown test.
1: 180psi -- 30% leakdown loss
2: 180psi -- 25% leakdown loss
3: 185psi -- 25% leakdown loss
4: 185psi -- 30% leakdown loss
5: 198psi -- 23% leakdown loss
6: 190psi -- 28% leakdown loss
I can hear the air coming from the timing chain, so I'm sure its the rings right?
The car seems to drive and idle perfectly fine...does this seem normal for loss of 30% or could my gauge have been reading it wrong. This was cold and dry. I did not test /w oil...although maybe I should have to confirm rings. There was no sound from dipstick or intake/exhaust.
Do I have anything to realistically worry about?
Next up front flex disk then bleed brakes + fit 400E brakes on front
....I can bet the brake fluid is at LEAST 5+ years old. Its gotta be...
Flex disk is the last "major" repair I need to do. After that, I have basically caught up and everything following is purely for fun.
