Hi all! New guy here and have a problem. I have a Honda Masters HR 215 KHXA, absolutely love how this thing runs and cuts however an oil leak has developed that dang near empties all the oil in one cutting! Been stubbornly filling as needed but is geting ridiculous. Seems to be coming from the gasket between the cylinder and the oil pan, directly under the clinder head (not the head gasket) . Have looked at some parts diagrams and see the gasket needed but also see something called a Pipe oil defense (Honda code 182502). Where this is shown on the diagram is right where the leak is. What is this part and will it likely need to be changed as well? Anyone have any experience with this? If it helps here's all the info from the mower-
HR215KHXA
Serial # MZAM-6297388
Engine family 2HNXS 1351AL
Thanks in advance for any help or info!

I'm taking a shot in the dark here but maybe there a o ring on the bottom of the tube.If you clean it real good and start it you will see exactly where it coming from

Thanks red! Cleaned it up real good and can definately see oil spurting out the front of the oil pan gasket. Yes, I said spurting! Not just a seep. This oil stop defense must be internal, nothing on the outside of the engine, or possibly my particular engine doesn't have this part?

hope it works good after repair

I have the same engine, on an HR215SXA a commercial model about 20 years old. I have cleaned and replaced the o ring at the bottom of the tube and I found mine is leaking under the flywheel. It has to get warm before it starts to leak. I am going to pick up the part as the local shop says I should be able to pull the flywheel and replace it without a tear down.
I will post back on my results.

There is an oil defense pipe (internal) on the GXV140. It's a pressure fit

I suspect the pan gasket...

Don;t mean to steal away from the thread, but for Ida-Boy, when you get ready to replace that seal, here's a seal driver I made for doing the sort of thing you're going to be doing.

Get a PVC adaptor that's got a threaded end on one side. Saw the threaded portion off leaving a flat surface on one side with a nice hole in the middle. That hole will fit over the shaft and the flat surface will push against the seal. Sorry for the fuzzy pictures, gut you'll get the idea.



Then use a length of pipe or PVC that's longer than the shaft your going over and drive the seal in nicely.





I first used it on the B&S in the pictures, and since used it to drive in the lower seals on Honda GXV120s.

I have ordered the top seal #35 and the gasket, #9 in the parts diagram and think that may do the trick. I will post my findings.

Thanks for the tip on install. I have some stuff laying around in the plastic fitting department that may just do the trick.

Did the install and I found after the engine warms up (5 to 10 minutes) she started to leak oil once again. Did what I could so now the question is to buy new or take to shop.

**Update** I installed a new seal and gasket for the oil breather on top of the engine and she still leaks. It is very hard to see where the oil is coming from. It has to warm up before you see the oil and it appears everywhere on top. :confused2:

Ida-Boy, I have the same mower and it is doing the exact same thing. I replaced the oil seal at the top of the shaft and it didn't fix a thing. The problem is that by the time you remove everything, including the flywheel to get to where you could see where it's coming from, the evidence is gone. I see one hole under the coil that is not threaded and I am wondering if that is some kind of pressure relief port that sticks open when it heats up??? Anyone know anything about that??

Sorry, I forgot to bring this up to date. I took the mower into the shop and they replaced the seal under the flywheel. It seems as if I tore it or pushed it to far into the seat. They installed a new one and no more problems.
In the mean time I bought a new Honda HRX217HYA and don't like it. I can't get a side discharge chute for it... Bummer!
At least I have my HR215SXA. Still mows strong at 22 years.

Interesting. Maybe I pushed mine too far into the seat. Is it suppose to be flush with the top of the hole? I guess you probably didn't get to see it because they had it put back together when you went to pick it up. Thanks for the update.

Possible, I can't remember what I used to push it down... I think I forced down by hand and then popped it with a plastic mallet all the way down... I do know they had trouble getting it out. The seal isn't that much so if it were me I would get another, lube the shaft with some oil (getting to sound kinky) and NOT force it past the top edge... try to leave it flush once installed and not force it into the cavity.
It defiantly forced mine down into the cavity like you. Just may have been the mistake.

Well, I dug out the other new oil seal that I installed incorrectly and pushed a new one in, flush with the top. Problem solved! Thanks Ida-Boy!
