Thanx, Insubordinator, but I think this drip is a bit more involved. When I checked my level after getting home yesterday, it had lost about 1/3 of the oil it had when left home yesterday morning. That's enough to have me a bit concerned.

You probably do have something relatively serious going on. Losing that much oil I’d think you’d have a lot more oil coverage than what your picture showed. Pull the airbox and see how much oil is inside. You could be getting back pressure which is forcing oil through the breather in to the air box. I believe bad rings can cause that.

Do a compression test, you can rent the equipment at any auto parts store. Cylinders should be within 10% of each other.

So can a holed piston. A Compression test will give you more information you need.

Good luck, C.

I would not run the engine anymore as it is about to fail in a big way. You have a piston/rings that are possibly the victims of detonation. Start with the compression check and see which cylinder is failing. Drop the oil and see if anything shows up there. Sorry but it's not looking good when that much oil is pumping out into the airfilter. :(

I'm with Msblu79.....there is a lot more going on than just a leaking rear main seal.....that is just a symptom of the problem. If you haven't already, talk to the shop and have them do a compression test.

Shop is pulling the engine and replacing the main seal, will also check for 2nd level effects. Going to be pricey...

A blown main seal can be a second-order effect of a blown piston. That's how mine worked out: destroyed piston and rings allowed combustion gases to slip out of the combustion chamber, over-pressurize the crankcase, and push oil out of every seal. Nasty.

If it's been burning oil for a long time, a chance the crankcase vent system is plugged up. If the crankcase can't vent the pressure builds up and it'll eventually vent somewhere. Usually it's an old tired/dirty/marginal seal.

We're just guessing guys, someone needs to actually go inside for a look....

Agree, it hasn’t been burning oil for a long time, I parked it as soon as I noticed it and got it to the repair shop. Waiting on him to get to it and let me know the verdict.

So, an update of sorts. After working thru the potential causes one by one, the engine was finally sent to Heindl ‘s to be rebuilt (new cylinders, pistons, rings, etc) and then shipped back to VA where it is now awaiting a new crank and rear main. Once that is complete, I think it “should” be good to go, hopefully in a week or two. This has truly been a nightmare, since I took the rig to the repair shop on 3 June, 2019....

Looking forward to hearing the verdict.
When it comes back, as mentioned in the first page, I'm only an hour away from you, own four Urals, and have a fully stocked shop, so let me know if you need help.
