Got chance to get my hands on a compression tester, I had suspicions that head gasket was going, its leaking oil and water, and looks like there is oil in the water.
Results
Cylinder1- 145psi
Cylinder2- 150psi
Cylinder3- 155psi
Cylinder4- 155psi
I don't really know where to go from here, any help would be great
Cheers
