Before my Z, i was a big honda guy, i built my turbo intgera to 475hp (this was like 7 years ago), but it took me 8 engines to get it right, back then, everything was new.(block sleeving, stand alones ect). Things got so bad trying to dial in my TEG, that when something didnt run right, the first thing i was doing was a compression test. (its alot easier on a honda)
Sucks to blow up, hardcore people do. Hopefully its a head gasket, and not the bottem end. Sucks pulling out a VQ
good luck

not necessarily....black smoke/blue smoke has been reported with oil overfill issues or bad turbo seals...

the only way to know is do a leakdown and examine the plugs, throw a boroscope down there while you are at it

good luck jorge, keep us posted, i tried calling u but your phone wasnt working

I did a compression check yesterday and it was good.

results

1. 115
3. 115
5. 110
2. 120
4. 120
6. 125

The oil on the plugs might be due to valve cover seals and o rings going bad. I have oil on all 3 driver's side plugs. The other side was fine. I will have a leakdown test performed tomorrow to make sure the motor is not damaged. From there we can determine if the valve cover seals and o rings have gone.

So far I am good with two test. I had the coolant check for carbon to see if the head gasket had blown and that came back good.....two for two....let's see what happens with the last test.
