Steal of the day, a 2146, now I need help fixing its oil leak
 

So I'm tinkering away in the garage working on replacing a PTO side oil seal in a CH18 and my neighbor from down the street pulls in. He says to me "Would you be interested in another Cub?". Well naturally I tell him I'm listening :biggrin2: We ride down to his place and it turns out to be a 2146. All and all, it's in pretty darn good cosmetic shape; missing the decals on the hood and a couple scratches on the fenders but otherwise, very solid; no real rust to speak of. He tells me it has a flat front tire (duh), needs a battery as the one in it won't hold a charge, and it has an oil leak. I look at the hour meter, she's still a young buck at only 402 hours. He asks me what I'll give him for it. I look it over, try to figure what I can part it out for, and tell him "Look, I don't want to lo ball you, but to me as it sits, it's worth $50, MAYBE $100." He says would you give me $100, I tell him let me sit on it for a day, and he says "I tell you what, you give me $50 right now and it's yours.". Well that was an easy call, deal!

We add some oil, jump start it, and it fires right up. I hobble it 2 blocks home and let it idle a bit so I can see where the leak is coming from. Below is a pic of the leak, and a video of where it's coming from. Having never dealt with a Yanmar motor before, can anyone tell what the problem is, where the oil is coming from? If I can fix the oil leak, I may keep it or flip it for some easy cash. It doesn't look like it's coming from the head, but where else could it be? :bigthink:

I did a little digging through parts breakdowns and checked a couple bolts. I found the bolt circled below to be nothing short of stripped. :angry: Any ideas how I could fix this? It seems like the only place it could be leaking from; there is no oil coming from higher up on the cylinder so I seriously doubt it's from the head gasket. Any suggestions how to fix this guys? :bigthink:

Pull the engine, remove the front cover, heli-coil the stripped bolt hole. Put it back together.

That's what I was leaning towards. Yet another engine I have to pull now :biggrin2: I've got one on the bench getting a new PTO side crank seal, one waiting to be pulled to replace a flywheel side crank seal, my fathers Wheel Horse is waiting to be put back together, and now this one! I think I need to catch up before I take on any more projects :biggrin2:

For $50.00 what do you want? :bigthink:

I'm not complaining! For $50 I did very good I believe, I knew what I was getting into. But just like many here, the projects keep piling up quicker than I can get them done! :biggrin2:

"A man needs to know his limits" LMAO I've stopped adding projects until I finish the one's I already have. Oh yeah and I'm retired. :biggrin2:

Yeah yeah yeah, rub it in! :biggrin2: I was doing good at keeping up with the projects as they came in, then I got bombarded! :biggrin2:

heres a 5 step solution to the problem
1. remove bolt
2. clean bolt and block
3. cover bolt in silicone
4. install bolt
5. sell it
:biggrin2:

im not familiar with that engine but would you be able to use a thread chaser or maybe tap it to the next size with out taking it apart? if oil comes out that hole when its running you could tap it then start the engine and the oil will push the shavings out.

No. You can't do that.


Ryan, I think the issue is the tires on the front. One is flat and the other is bald. :biggrin2::biggrin2:
