Last night i finally got hold of compression tester and here are the numbers:
1st turn, 2nd turn, 3rd turn

Cyl 1: 110, 150, 170
Cyl 2: 115, 160, 180
Cyl 3: 120, 160, 180
Cyl 4: 120. 190, 200
Cyl 5: 130, 170, 210
Cyl 6: 150, 180, 195

Margin of error approximately -5 psi

Cylinder 6 was oily inside, by the exhaust smell and signs of smoke seems like engine is burning oil. Judging by those numbers is my engine good for another 200K or should i be looking for another one?

cyl 4-6 im sure have alot of carbon build up and/or oil sitting on the piston . 180 ish is good solid compression on 10;0:1 c/r

Thank you, how does oil get inside of cylinders in such a big amount? When i was assembling everything back oil was all over intake manifold and all connecting pipes, oil return hose that goes in front of throttle body was all kind of dirty and seemed like it was just dumping oil into intake. Is it normal to have so much oil in intake system or is it broken valve(EGR?)?

this a turbo engine??

If it is GTE then this is bad. You should have a range of no more than 15. It is stated in the repair manual. The goal is not to have super high in each cylinder but to have each cylinder close together. That way the wear is even across the board. I would do a leak down test.

No it's not turbo, it's just old GE with 212K on it. Funny thing, area around throttle body makes weird super loud high pitch noise. When i move intake hose it changes tone. Could that be related to PCV ? it wasn't making noise at first, maybe after 10 minutes running i heard it starting and now every time i start the car it's present. Sounds like a whistle
