Mobil 1 15W50 is supposed to be the oil for turbo cars anyway isnt it?
My car is at 175,000 miles and I'm pretty sure I now have a blown HG... radiator has developed a hole in the top that visibly leaks even when not under pressure and it boils off all the coolant in the system after about 60 minutes of steady driving... after driving for ~20 minutes you can stop and turn the car off and tons of steam comes out
I guess I'll be doing a new headgasket and prolly new valve-seals while I'm at it. Anyone know if its cool to use a thicker metal headgasket to lower compression down slightly?
