i checked the oil and coolant and i see no mixture.i put oil in the cylinder and it only shot up to 190 while the others where around 220-250.I dont understand this compression test or trust it.its only when it heats up it starts smoking and to me it looks kinda blue.I did 2 induction services and changed the plugs and theres alot less smoke.I really dont think its a blown headgasket car runs to nice to be it.
