Is my headgasket blown
OK here is the problem i have.
The car started to smoke. Cold start- no smoke. Light driving- no smoke. When i get on it- a bit of smoke. When i boost a lot and come to a stop and rev up a crap load of smoke comes out. Its bluish white. Smells a bit sweet and oily.
So i did a compression test it showed 205, 210, 175, 205. Leak down test did not show much but there was a considerable noise in the oil cap.
A few days ago i pit a bit of sea foam into the oil. Drove around for a bit( like 30 miles maybe) drained the oil and it was really black. After filling up the car with oil again i started it up and drove around the block.
I opened the oil cap and shined my handy UV light in there and everything light up greenish. I have a special dye in my coolant, i put that in when i had a coolant leak. I turned over the oil cap and it had a bit of milky residue, barely seen. With a UV light i could see a bit of greenish stuff tho.
After i removed the valve cover the oil in there was green and i could see that without any UV light just pain green.
The car does not over heat and ran fine besides smoking.
What are the chances that the smoking is from a bad head gasket?

the headgasket was leaking pretty badly on 2nd and 3rd cylinders. The cylinders were actually steam cleaned. So i had the spare head rebuilt with all the seals. I put in the stock composite head gasket, because they seal better and i reused arp head studs. Its all good now. No more idle drop and the car runs much smoother and most important does not smoke at all.
