lots of good information over there for you.

I already did it
thanks

Comp numbers look very good, was this wet or dry an warm or cold? Delta should be less the 10% between cylinders so your fine.

Hi thanks for the feedback

its was warm and dry.
The leak down net me 2% max and 1,8 minimum so I guess the motor its running good.
the motor drinks 0.6-7 liter every 2000 km so I guess everything its normal.

Regards.

Those compression numbers seem strong compared to others I’ve seen posted.

Maybe your pcv valve or valve cover gaskets are causing some of that consumption?

PVC its dry and function perfect , I need to change the valve covers … just waiting the damn thing to arrive.
its leaking a lot probably its the 40-50% of the consumption.

Regards.
