Head gasket problem

[CMF_demonical]

Could a blown head gasket result in smoking in the sump ventilation.A friend of mine was mapping the car with the new Megasquirt ECU and after a one of the 3rd gear pulls it went in to Subaru mode (3 cyl) no strange smoke from the exhaust.This morning i unplugged the sump vent that one to the dizzy and it smoked from there

No it's naturally aspirated cg13de with cg10 pistons and some headwork,i guess the base maps we run had a too big advance setting and melted something.Will report back when i open it up.

Some progress did a compression test and all of the cylinders were near 15.8 bar :O i guess something with the gauge might be wrong butt all 4 were almost equal, tryed letting the ventilation open with two hoses going down to the side of the gearbox butt it was smoking pretty much so returned them to the original state one to the maniford and the other one in the airbox.Overall the car is pulling good, when you run it
10-50 % tps it's running smooth when you blip the trottle it bogs for a sec and then revs.The main problem is when driving lets say in 3 rd on 3k rpm and you decide to overtake and give it WOT just then you can hear that one of the cilinders is missfiring.
