Default Oil spray from head gasket--

I just came across a thread where a poster said that even with a head gasket reversed, oil should not be spraying out.

My situation is:
1.8L '93 with 94000 miles, drive 300 miles freeway weekly, little to none in town.

Had some hesitation/stumbling on highway out of the blue. No overheating. Got it home and noticed a good amount of oil sprayed all over the exhaust and passenger side axle/general area. Closer inspection shows oil build-up and leaking from passenger side head gasket on firewall side. Also some wetness/oil residue on top side of same head gasket.

I've just been thinking of it as a worn/failed head gasket, which I've heard is fairly common. It never even got a little warm, oil level is good, is changed at 3000, and never smelled burnt or very dark. Also no trace of oil in coolant.

Is there any reason to think the crankcase is being pressurized? Although my oil appeared to be sprayed, I think warm/thinned oil at 70mph might just naturally splatter.

Any thoughts?

The pressure port on the head gasket is on the top I think it is in the rear of the right head and on the front of the left head. If it was the pressure port it would be spraying up. For your block to be pressurized enough to spray oil your pvc and valve cover vents would all have to be pluged. I would think that it is just blowing around.

Thanks a ton- It still runs like a top, but I obviously am not going to let the head gasket go.

I'll just go forward with the gaskets and timing belt/water pump job.
