Oil leaking from petcocks before starting

Carl

Consider that oil is being distributed all along the cylinder walls through the ring land holes in the piston. Also when it is shut down, what oil is there tends to migrate to the bottom of the cylinder right where this hole sits just waiting to be filled with something. Even if the engine is run hard at operating temperature, that's still NOT hot enough to vaporize this oil. At least we sure hope not, otherwise you'll soon have more problems to worry about than a few drops of oil spitting at you at the next start! Because the rings can't scrape the oil out of this hole, some collects in the hole while runnng plus a little more once parked and it stays there as long as gravity is at work, the green side is up and the black side (the tires) are down. That oil stays put 'till you open the relief valve and then phhht out it dribbles right in your hand or up your wrist.

The time to be alarmed is when you one day open them and gasoline or antifreeze starts to run out and continutes to do so. Those however make up a whole other set of stories!

One of the petcocks on "Easy" my 46A leaks oil.

I have replaced at least 3 or 4 "leaking" petcocks on other tractors.

One thing you might try is replacing the petcock with one that has a stronger spring.

You might also "expand" the existing spring and see if that solves the problem.

Hope this helps. Thank you again for your service.
