Small engine oil leak (extreme) repair Empty Small engine oil leak (extreme) repair

Post by 12acrehome on Sun May 11, 2014 3:51 am

About three and a half years ago DW and I bought what we thought would be a quality, durable riding mower. A cub cadet SLTX 1050 (http://www.cubcadet.com/equipment/cubcadet/sltx-1050). Well this thing has been out of service and in the shop more than it's been here and ready to use. Very disappointing, especially considering the purchase price. The right hand cylinder head has always leaked oil. This is particularly bad on an air cooled engine that operates in a dusty environment, since the oil coats the cooling surfaces then attracts dirt, then more oil, and more dirt...The end result is an overheated engine, and possibly a fire in the engine compartment, that also houses the plastic gas tank.

So today I made what I hope is the final attempt at repairing this problem. I may have actually found the root cause of the problem this time. The factory design relies on sealants instead of gaskets. These chemicals need a rough surface to adhere properly. I found a section of the sealing surface on the head that looked like it was polished smooth.

So the first thing I did was rough up the area with 80 grit sand paper.

Then (like I planned to do before finding this) I cut out a gasket from some cork I had laying around.

next I applied high temp "gasket maker" to everything.

Then assembled everything loosely (to prevent pushing the sealant out of the area that needs to be sealed.

Now I just need to wait and let it all cure, then tighten down the bolts and see if it worked.

Thank you both. We are to the point that if this doesn't fix it, it probably can't be fixed.

If any oil seeps through all those barriers I'd say it definitely wasn't meant to be repaired. I've had good luck with the cork/cardboard and gasket maker compound for sealing most leaks like you are having.

So, I will never recommend a Kohler engine, nor a Cub Cadet to anyone for any reason.

Talked to the local "brain trust" about this, gonna try one last thing. (Well actually two at the same time) A different cleaning method, and a different RTV gasket maker

me too, this has gone way past tolerable and far exceeded manufacturing variances. Four years old, and has had a potentially catastrophic oil leak for more than three years, even after my two attempted repairs and the local "repair shop" attempting repairs three times...just enough to run the warranty out.

Have you contacted the company directly? They may have something like a Lemon Law in place for defective engines. ??

Oh believe me I've had the corporate guys on the phone...lawnmowers don't fall under the lemon law, and because it actually does start, run and operate as advertised there is no legal recourse. So my word against theirs that an oil leak will lead to other engine damage.

very true, and that's why there is no such thing as customer service, no such thing as pride and workmanship, and why craftsmanship is dying.

Well, I got it stripped down, cleaned up and back together today. Pulling those heat shields is a real pain. I had to pull the carburetor, the fuel pump, some of the wiring, move the governor linkage...not recommended for the mechanically challenged.

lots of sealant, now if it will just cure up like it should, and actually seal this thing

thanks Patrice...time will tell, other repairs lasted anywhere from a couple of weeks to a couple of months

Have you tried making a gasket from a cereal box? We've had luck with that when other gaskets failed. We used a gasket sealant along with it.

no, not a cardboard gasket...what I tried seems to be working, but so did all prior attempts at first.

Actually I have an e-mail request in to Briggs and Stratton asking for a cross reference to replace this Kohler engine with...I may also consider a Tecumseh motor, but this is definitely the last Kohler I will own.

The combination of the cardboard and gasket sealant works pretty good. The cardboard absorbs the oil, swells and seals against the imperfections in the metal. It might be worth a try if you have a problem in the future.

I actually thought about that harvey, but it's an aluminum head and a steel cover.

Besides that there are regular valve adjustments that are supposed to be done...

and if I decide to destroy this thing I want those covers off so the flame can reach the fuel inside the block
