Oil being pushed out of the crankcase ventilator

I see in your old post that you talked about smoke coming out of the ventilator.  Take the oil cap off with engine warm and at idle.  Do you see a puff, puff, puff of smoke, a steady stream of smoke etc ?  

Just a thought…. haven't seen the old post. But have you done a compression test on the cylinders?

That's a very bad sign.  That's blow-by and it means that compression is blowing by the rings.   That's what makes the high crank case pressure and it's what is blowing the oil out the ventilator. 

You should really inspect the intake system to see if there is a cracked hose or other problem that let it suck dirt into the engine.

From what I can tell long distance you are going to have to at least an in frame overhaul on the engine.   You should really find somebody that can do a compression check to verify.  

I concur with Larry.  

The “puff puff” of smoke and not steady suggests that one (or more) of the cylinders has bad/broken rings. See if someone you know has a compression tester. Or you may find one for a cheap price. Can you say… “harbor freight?” 

Do the test first to confirm it. If it does indeed show a bad cylinder, then you will have to tear it down and replace the rings. You need to get a good look at the cylinders to make sure it didn't score the cylinder walls. If that's the case, then you'll be in need of a good machine shop or replacement if it's really bad. When you put it back together, replace all the rings and I'd also suggest new rod bearings since you are in there anyways. This keeps you from having to do it again for awhile.

You can make a compression test or leak-down test adapter from an old fuel injector or an old glow plug. You're not likely to find the correct adapter in any kit.

If you have compressed air handy you can perform a crude leak-down test with just a rubber tipped air nozzle stuck in the injector hole. Max. 20 psig.
