So I'm really hoping someone here can help me out. I just picked up an '85 MKII for $100 from the original owner and it's supposed to have a blown head gasket. I don't know that he ever even had a mechanic look at it and I'm also unsure of how much he knows about it himself. I brought the car home and started it up. It ran fine after a little coughing and sputtering obviously resulting from the fact that it hadn't been driven or even started since about October. All that aside, I let it run up to operating temp and then cool off, and back up again. There is obviously an oil leak in the engine compartment somewhere because there is oil smoke coming from under the hood. Aside from that, I can detect no oil smell in the exhaust and no obvious antifreeze odor either. There is a slight white-ish vapor of some type coming from the exhaust, but it's very light and I can't even tell if it's anything abnormal or not. Is there a good way that I can confirm a blown or leaky head gasket? Would a compression test do it? I'm open to suggestions. Thanks much!
