Oil getting into the intake
I just had my head gaskets replaced and now there’s oil getting into the intake. Can a rebuild kit fix this problem? If I’m going to replace my engine, my original 8th digit vin letter is R and the one I’m replacing it with is vin T. Will this work?
Try replacing the PCV valve first. Oil may be getting into the intake from a failed PCV valve or improperly installed gaskets since you just had it worked on. A compression test will confirm if the problem is internal in the engine or not.
PCV valve location
To remove rotate PCV valve(3) counter clockwise 90 degrees.(5.7L engine shown)
