Default Briggs WA

I broke in a Briggs WA today. What a beefy thump'm motor. I didn't have a crankcase breather so I made one out of a pipe nipple and the top of a round finned FH breather. Had a lot of blow by out that set up. Does anyone have the right breather or similar extended breather they would want to part with? I possibly may have another problem if the oil want to pump up the tube. Any thoughts?

Thanks
Al

I'm going to give this a try. Going to use the same breather set up but I stuffed the 8 inch tube full of the steel Chore Boy scrubber. Followed that up with a screen and a pin to hold everything in place. Seems to be a nice breathable baffle.

Al,

Don't ever use steel scrubber or wool material in a breather. It will rust and the particles will end up in the crankcase. You don't want rust and small steel particles floating around your crankcase and in the bearings. Use copper material in your breather and you will be good to go.

Junkologist, thanks for steering me straight on that steel scrubber. I'm glad I posted my misguided brainstorm.


Don, thanks for the options but I think I'll hang onto it and enjoy it for awhile.

The scrubber I used ended up being stainless so it probably would have been OK. I still removed it and used copper. Softer stuff should there be a problem.

mr allen, not a problem, if you never ask, you will never know. if you have a manual, send me the part number, i will look at my other engines and see if they were used on more than one engine.

Alan, you stated that you "had a lot of blow by" in this engine you were braking in. Not knowing how complete of a rebuild was performed, I am tempted to think that maybe one of the piston rings got installed incorrectly ? There are alot of variations of piston ring designs, and it can be difficult to see the differences between 2 sides of the same ring. Just a thought, not trying to say you don't know what you are doing. How about showing us a picture of the seldom seen WA ?

Hey Allen,

I read the first entry you made to mean you are getting a lot of oil
coming out the top of the home made breather tube as engine runs. I had a little Nelson Bros engine that did the same thing when a section of pipe was used as a breather, just as you have happening now. I think an original Briggs / Stratton breather will solve your problem of oil coming out the top of the breather tube.

The blow by problem wasn't from the cylinder. The problem that I was having was oil pumping up my homemade breather tube. I have packed a
copper scrubber into the 8 inch pipe nipple to use as a baffle to keep oil in the bottom. I then followed that in with a screen and then installed a thru pin to keep everything in the tube from falling back into the botton. I've haven't tried it out yet so the verdict is still out. Here's pics of the engine, breather and sparkplug after initial break in. Look pretty good.

Everett, I've been looking for an original breather but they seem hard to come by. My plan B is to use a breather off one of the smaller engines and mig it to a black pipe nipple. Seems like that would be a good option if I can make it look good enough.

Hey Alan,

Nice engine, nice job. That spark plug looks just great as far as color, with no oil showing on it. Here are a couple pictures of my own WA. Got it right
here, off the Stak's classified's section. I put this one on a small set of engine trucks finally. Too awkward an engine for me to just horse around anymore. Ha!

hi,the breather you have on your WA should work fine.Depending on the year.you have the proper breather.In the early 30s briggs changed breather and went to the larger breather.I have a W, Q and a couple of model Rs with your style of breather and there is no problem with them blowing oil.It appears that you have to much crank case pressure For some resson.nice looking engine.thanks ken
