blowing oil from exhaust?

Why would oil blow out the right side of the exhaust on start-up. Are the rings gone on that side of the engine?

All I know is , when the engine is fired up, and you stand in front of the right side exhaust, you'll get sprayed with oil!

After engine runs a few seconds, it stops and doesn't smoke or anything?

Any ideas?

worn valve guides or seal allowing oil to leak past when the engien isn't running and builds up in one or more cylinders.

might also want to look at the oil drain back holes to see if they're restricted.

I've not pulled the valve covers to check for blockages or seal trouble yet. Other people have told me the same thing, ede.

It is definitely oil coming from the right side pipe. When I felt of it, it was slick and also smelled like oil.

Someone told me, if it was the rings, it would smoke all the time.
Also, I should check the PCV valve, I guess.
When I get time (who knows when), I'll get deeper in to checking things out.

Thanks, folk!
