Blow by Problem?

[Mike 0]

On a 7112 (I don't have a book) is there a Crankcase Breather Valve or Filter? I seem to have a lot of blow by coming out of the oil filler tube. What could be the problem. I don't have blue smoke so I don't think its rings but .... Any thoughts? Tuffy

IT SOUNDS LIKE THE BREATHER TUBE FROM THE CRANKCASE MAY HAVE A SPLIT OR CLUGGED UP, THIS SHOULD GO IN THE AIR CLEANER ON THE CARB,,WORTH A CHECK ON IT GERRY

Also check the dip stick seal for leakage. If it slides out easily or is damaged it could also cause crankcase pressure, as could a leaky seal, crankcase or pan gasket or faulty breather also. The Kohler breather uses both a fiber screen and spring reed type valve.

Sounds to me like your top compression rings are worn or weak allowing compression[blow-by] to leak down into the crankcase,hence the 'steam'coming out of the fill tube.The crancase filter is located under the carb. behind that tin plate with a single nut holding it on.But I don't think that's your problem,Probably needs new rings.Also the fill tube is supposed to have an o-ring on it to seal it!. dlc

Jeff, where is the "Kohler breather with filter" located?
