My bother and I rebuilt a pony tractor (engine pretty much all new) about 3 months ago, I have been breaking it in according to the manual. I changed the oil again and I am now starting to cut some grass with it (woods L59 Mower) I rev the engine up and cut some grass, when finished I noticed the blow by tube has dripped some oil (it isn"t much) but should it be doing that?
I don"t know what they did when they were brand new, so I figured I would ask and see if some of you antique tractor experts know if that is typical to drip a little oil. I rebuilt it because it needed it bad, there was a tremendous amount of end play, it was knocking, smoking. Not doing any of that now. No smoke, and I don"t smell oil burning.

Mean while I notice the brand new front seal is leaking a little, so I need to replace that. It is getting around 30LB of oil pressure. Other than it sounds and runs good. Can"t wait to replace all the seals in the rear.

If you used stainless rings it will take a while to seat good or there is something wrong with your valve lifter cover oil breather separator tube.
Hope this helps John

New pistons 30+, rings, valves & roto valves, valve guides, springs, keepers, bored 30+, welded thrust area, welded crank (STD), reconditioned rods, New main bearings (STD), New rod bearings (STD), Lifters refinished, New seals, New gaskets all over the engine, New thrust shim, New oil pickup tube with screen (original was missing the screen and the oil dipstick was found in pieces in the bottom of oil pan) New oil dipstick, Everything in the engine except the cam is pretty new or reconditioned.

It isn't dripping oil really bad, just a drop ocassionally, It only does it when I really rev it up and put a load on it. I figured it was doing that because there is no baffel or foam or anything over the blow by tude on the inside of the engine. I figured maybe oil is splashing and moving around in there and it is running down the blow by tube cover and into the blow by tube and out. (I put my finger over the hole and it isn't blowing out, kind of feels like an in and out motion?) It sure does sound good when running but I am just not sure if it is to drip oil on occassions.

I can gas it about half way and just putt around with the mower running and cut grass just fine with out a drip, but when I get into some really tall grass (over the front wheels) and the pony has to work is when it does a drip or two. I just take a towel and wipe the drip off the frame. It just want to make sure nothing is wrong especially after all the money I sunk into it. My brother says it is fine, he knows more than I do on engines.

Did you bore the block and new pistons or use the stock ones?
