HELP! Compression and leakdown results, possible blown headgasket?
HELP! Compression and leakdown results, possible blown headgasket? The car started idling bad, had pressure at the oil cap.
Was smoking constantly white/blue smoke very heavy.
I pulled the plugs and #5 is wet and covered in oil.
Compression test - 5 cylinder was about 30-45 psi, #7 was at 90psi all others were at 160psi (cold)
Leakdown - I'm getting 0% on #5
Coolant in Rad seems to be low, car was never overheated.
What's my next step, pull off the head to check the headgasket? Can you actually see on the gasket when it's blown?
Any other suggestions as to check before I remove the head?

should I pull the head, will I be able to see if it's the head gasket once I pull the head and look at the gasket? Or are the holes so small I won't be able to see with the naked eye?

excellent, I'll pull it, I suppose I can't cheat by not draining the coolant because it will just go everywhere right?
So I have to drain the rad and engine block before I pull it then? Or can I just stick a towel over it once I pull the head?

Drain it. Even drained you'll still get some coolant splashing around. It will get into the bolt holes so make sure you dry the holes out with a paper towel or compressed air before you reinstall the head. My guess is that you will find head, piston, or ring damage if you have alot of oil in the cylinder and pressure at the cap.
