Kubota L285 oil oozing

Kevin Hi again

Another oil problem with my 77' L285(1500A engine). I have posted here before and got great help. Thanks Smokin Dog.

This time what happens is when cranking the engine, oil seeps out of a hole in the engine block. The hole is to the left of the dip stick and an inch or so higher than the dip stick. I would say the hole is about 1/4" in diameter (the thickness of a pencil) If the engine is started(only let run a few seconds)the seeping becomes a forced stream of oil out of the hole.

Have tried the following simple things for a fix... oil and filter change, checked the relief/safety spring valve bolts in front of the oil filter mounting.

Not sure what else to try. The hole that is leaking dosent seem to have any threads from what I can see(and goes in 4-6") so I am not sure if there was a bolt there that worked itself out. Could send a pic if it might help.

Any info or suggestions would be appreciated!

Kevin

Smokin Dog Can't be sure of your problem, however I had
a tractor that had a simular problem at the
tranny. A hole about 1/4 dia. No threads for
a bolt. The oil would seep out while at idle.
pour out when driving. I finally discovered a
small 1/4 inch flat plug worked it's way out,
and left a open hole. The plug popped in like
a freeze plug in the engine. My fix was tap the
hole with threads and install a small bolt to
seal the hole. Use grease on the thread tap to
prevent metal shavings entering the engine.
don't thread all the way to the bottom of the
hole, just a few threads is all that's needed.
You will find drillings of the type, they are
for cleaning out lines at the factory. Some are
for added on goodies needing oil supply. In most
cases these are never seen or start leaking.
just a place on the block.

Butch Think that hole your talking about goes directly
to the oil passage, don't run the engine at all
untill it's fixed. Smokin Dog has a great idea.
I would have drove a peg into the hole, that
would have done it but only for a while, and you
might lose the peg and engine.

Kevin Thanks Smokin Dog(again) and Butch. I topped off the oil, put a temporary plug in the hole today. Hooked up the oil pressure gauge and started it up. At idle it ran at 50psi and 75psi when revved up. I watched the plastic plug and the pressure like a hawk while it ran. I will give it a little longer test later and if all seems well I will tap the hole for a more permanent plug.

It ain't pretty but it ain't dead yet.
Thanks again guys!
Kevin
