Piston oil residue pics attached
« on: July 06, 2019, 12:30:04 am »
So my car is burning some oil notice it when the car is warmed up get blueish smoke when at a stop idling then pulls away i.e. Traffic lights seems to be ok on the move but then noticeable on the overrun
Did a compression test with engine hot
Cy1 180psi
Cyl 2 180.5 psi
Cyl 3 165 psi
Cyl 4 180 psi

Cyl 3 is a little low but would think is still above spec?
Then got a camera down bores to see pistons in order cyl 1 first pic etc
Cyl 3 looks the cleanest


Also do these look like standard G40 pistons cant really tell?
