dscott2000 1 #1 Posted December 18, 2009 Ok, I need some help. I have a pretty major oil leak on my k181s. The oil is coming out of the govenor shaft. Just where it goes in the block. Is there any way to keep it from leaking or leaking so bad? Share this post Link to post Share on other sites
rickv1957 70 #2 Posted December 18, 2009 I am wondering if your valve cover-crankcase vent assembly is installed correctly,sounds like you have to much crankcase pressure or your engine is getting tired,Rick 1 Share this post Link to post Share on other sites
dscott2000 1 #3 Posted December 18, 2009 I am wondering if your valve cover-crankcase vent assembly is installed correctly,sounds like you have to much crankcase pressure or your engine is getting tired,Rick Thats the thing.. I pulled the head off of it just yesterday and there are still hone marks in the cylinder. I think what you said about it being installed correctly may be the answer. I really am in the dark on this one. I am used to working on Briggs motors and Tecumseh motors. So, Kohlers are a little out there for me. Share this post Link to post Share on other sites
Rollerman 290 #4 Posted December 18, 2009 Is oil comeing out the governor shaft or the valve cover/breather? The governor sit's up pretty high & seems unlikely a lot of oil would come out of that point before escapeing the valve cover/breather. I'd clean the engine best you can & double check where the oil is leaking at. If it's the breather new gaskets are cheap, but a leak there may also mean other problems like worn rings. It could be also the brass nut that retains the governor shaft is wore oblonged & may need replaced. 1 Share this post Link to post Share on other sites

I have cleaned the engine a number of times and it comes from there. Do you have any idea how much that retaining nut costs? Just asking. Share this post Link to post Share on other sites

TT-(Moderator) 1,127 #9 Posted December 18, 2009 230476-S should be the part number for the governor bushing/nut. Make sure you pull the breather apart regardless. If it's assembled incorrectly, it can't vent the crankcase causing oil to push out of every conceivable (and some inconceivable) places, Here's the IPL for the breather itself (and the part numbers for the gaskets, filter, and seal ): The inner plate has to be installed exactly as pictured. The reed must be on the outside of the plate and to the right, with the small drain-back hole on the bottom and to the right of the mounting stud hole: Make sure nothing is blocking the oil return hole on the "floor" of the valve spring cavity. 1 Share this post Link to post Share on other sites
