I have noticed that sometimes I have steam coming from both of my exhausts. I belive it is stock, so banks should not be connected one to another. Coolant loss is minimal, but I have done a test for exhaust gasses in coolant and it came back positive after 4 tries with cooling in between, becouse coolant started to boil. Other than that I don’t have overheating issues.
Also did compression check, and it is as follows
5 12,5 10 13
4 11,5 9 12,5
3 12,5 8 13
2 12,5 7 13
1 11,5 (?) 6 13
I had a slight issue on cylinder 1 with my measuring setup, but I’d say it has at least 12 bar in reality.
Do you think that it is possible I have blown head gaskets on both banks at the same time? Smoke from both exhausts seem to be the same amount. I guess i could have coolant leak to manifold through PCV tube heating, but it would not give me CO2 in the cooling system.
Anything I missed, or I just have a bad luck?
I guess there is a possibility for cracked head or block, but I guess it would make even less sense to have a crack in both heads, or two cylinder liners, one in each bank.
