You are watching: Kohler engine blowing oil out exhaust


I have actually a Kohler CV740 27hp twin that ns just gained through rebuilding. (rings, seals, push rod, head gaskets, carb kit...ect) The just gasket that i didn"t replace was the breather gasket, didn"t also take the sheathe off. After reassembly the cranked and was running fine. Climate it began smoking....the smoke wasn"t coming v the exhaust it to be running the end onto the muffler indigenous the breather.Does the breather have actually that lot oil push on that to punch a gasket? when it was apart ns did remove and check the reed valves on the cylinder.

I attached a parts breakdown...the breather gasket is item #2 (top right) that fits in between the cyls....the reeds were put earlier in the correct order

Have the ring seated fully? that is possible you have extreme blowby that might decrease together the rings seat. Various other than that, I"d traction the breather, and also if the has any baffle, clean the baffle and make certain there"s no blockage the the drain ago to the sump.What was the condition of the bores prior to you changed the rings? go you rest the glaze on the walls? Hone in ~ all? to be the engine formerly blowing oil out or smoking?Either the breather or the rings...tom
i experienced a video clip on youtube critical fall about this precise thing. It ended up being a combination of breather and also a gasket under a coverplate between the cylinders behind the input manifold.

That"s no the breather, the doesn"t have actually one per se other than the separator on the valve cover. The is the high push oil ar that feeds the hydraulic lifters. Replace the gasket and also you should be all set. The pipe plug in the cover is her oil press pickup suggest for a gauge or sender.
SUCCESS
...New breather gasket come today. Once I removed the breather cover i noticed among the bolts to be loose...come to discover out it to be stripped..drilled that out and also retapped to 7mm set up the new gasket, torqued to 65in lb every manual finally got all the "banjo work" because that the carb linkages reinstalled and also she fired best up, ran it through out the muffler, as to check for leaks...none seen and also no smoke what therefore ever.....Time to complete putting the accessories on and the journey belt and see just how it go under load prior to the mower deck gets put under it.....:thThumbsU

THANK you... I had my doubt it was a breather... & the reed valves have actually a tube that goes come the carbohydrate intake.. To add he never said it was leakin oil... Just smoke.. The oil leakin was droppin ~ above his exhaust device & then smoking..

that gasket u just replaced is not a breather gasket .. It covers the oil galley that feeds the lifters with high preassure oil native the pump..rscurtis just confirmed that point..you had us every off track by callin that a breather..
That"s no the breather, it doesn"t have one per se except the separator top top the valve cover. That is the high push oil section that feeds the hydraulic lifters. Change the gasket and also you have to be every set. The pipe plugin the cover is your oil push pickup point for a gauge or sender.

Thats what Kohler calls it on their parts failure and on your packaging....A breather has to have somewhere to acquire air....and this don"t...good to understand what it function is and where that feeds....new gasket and also all seems well...
Breather is what Kohler calls that on their component breakdown, and also their packaging....They might need to re-wright your manual.Thanks males for your assist and input:thThumbsU
