Re: cracked oil line

I had this happen once. I cut a piece out of a coke can to wrap as tight as I could around the line and then wrapped duct tape over that real tight. The oil will blow right through tape alone. It will probably still leak a little but should get you home. I hope you have more oil. Be sure the stuff that leaked isn't on anything hot. That could be bad.

Re: cracked oil line

If it's a pin hole you might try putting the point of a small screw into the hole and giving it a couple of turns to stop the leak. Usually works.

Re: cracked oil line

If you know where the pinhole is, use a bit of hose , or even tape over the hole, and then an appropriate hose clamp done up tightly.

Re: cracked oil line

You obviously need to stop the leak enough to limit the loss of oil and control the mess, but I just read somewhere that it is not the oil PRESSURE from the pump that is responsible for separating the points of contact between the bearing surfaces. Just provide oil supply, and the oil will take care of it.

I'd like to hear what others say about that, but possibly you can back off on the oil pressure relief valve if you had to.

And as far as putting a screw in the hole, the oil line on my 3GM 30 was I'm guessing about 3/16 OD. Not much to put a screw in.

Re: cracked oil line

How about this idea.
take a rubber hose and cut off an inch
slice open the side so it can lay flat
cut an area of rubber to put against pipe small enough that it overlaps the hole but not big enough to overwrap itself.
clamp rubber to pipe with screw clamp.
