losing coolant, looks like oil in coolant, but 150psi compression on all 4? hg?

[jt15833]

I thought I had the symptoms for a blown headgasket likea) loss of coolantb) oil in radiator

but today i did a compression test and got 150 on all 4 cylinders. could it still be a headgasket issue? any ideas of what other leaks could cause symptoms like this?

yeah, it can still be the gasket. it just isnt leaking around the cylinders. fire rings are intact but some oil and coolant passages could be pwnt. i really dont know, it could be plenty of other things as well.... i know i get a little oil in my coolant because my head gasket isnt sealing properly at the back on the exhaust side. i still get 165psi across the board though. hows your gasket? is it stock? have you changed it in the past? im running a nismo MLS deal and i never got the head properly milled down, so thats whats causing my problems.
