Chrishar 544 #1 Posted March 2, 2023 Have a k181 kohler engine that is putting oil out of the breath cover when it's running what can I do to fix it 1 Share this post Link to post Share on other sites
rmaynard 15,450 #2 Posted March 2, 2023 Has the breather been recently removed? This usually happens if the breather is reassembled incorrectly. If not, maybe the reed valve has failed. 4 Share this post Link to post Share on other sites

I believe he is referring to the inner plate drain hole - it HAS to be installed so it is at the bottom - and can be installed wrong!! 1 Share this post Link to post Share on other sites
squonk 41,099 #4 Posted March 2, 2023 Either the reed and or gasket failed or it's time for a ring job. 2 Share this post Link to post Share on other sites
953 nut 55,215 #5 Posted March 2, 2023 Is the engine burning oil (white smoke) or having signs of oil fouled spark plugs? Remove the dipstick and run the engine, is there a lot of pressure at the dipstick tube? Share this post Link to post Share on other sites

To add to that, I would check that the drain hole is clear. Maybe some junk blocking oil from returning to the case? 1 Share this post Link to post Share on other sites

squonk 41,099 #11 Posted March 3, 2023 When you say " Rebuilt" was the bore checked by a machine shop? How was it measured? Most guys see a cross hatch in the bore and think it's still good but in reality the bore is tapered or out of round. New rings are tossed in and that will get you by for a little while. Then they start blowing by resulting in exhaust smoke, oil out the breather or both. 2 Share this post Link to post Share on other sites
