Listeroid Engines / 2nd Fire...Breather slober....and why.

I did a tear down of my first 6/1 to correct a few issues like growling bearings in the ST and paint everything up nice. I didn't know how well the portable idea was going to work out and skipped the make it purdy part. The rod bearings looked good Timken’s everything looked fine. It always wanted to loose a bit of oil out the breather but nothing a rag wrapped around it couldn't handle. I always suspected oil running down between the precision sheet metal splash guard on the inside of the breather inspection cover was the culprit so I straighten it all up so it sealed good against the inside of the cover. I had the crank polished put in a new set of rod bearings a new gasket set and did a fuel filter upgrade. Then came the time for the 2nd fire.....got it all bled out...what a pain! Someone on here mentioned pressurized the fuel tank and that seemed to aid in the process. She fired right up and did great. I adjusted thing and tightened up this and that then noticed a good flow of oil coming from the breather. All those negative things came to mind! I didn't line the ring up right...or they were worn out...that will teach me to check the ring gap! But the way it was loosing oil just didn't make sense! If the rings were that shot it would not start and run so well. I have heard of others with this issue and the tied rag was mentioned, also blow by. Well I figured out what was the culprit in my case. If the precision sheet metal splash guard has to small of an opening the air on its way out picks up velocity taking oil with it. 3 hours might dump a quart. I pulled off the inspection cover and took a screwdriver to it and bent it out so it had a big air passage. What do you know it no longer pukes out the breather.
