Hey Guys,
I hate to keep comming back to this but my water leak into the pan is still there. Latest attempt was K & W head/block sealer, followed directions and still leaking. Tech.support said it was for pressurized systems only (now they tell me). Some of you rebuilders use a "block sealer" and I was wondering what might work. I know this question has been asked before so apologiezs in advance for asking again.
Thanks Again, Pete

Pete,
K & W is good stuff. I think you need to figure out WERE it is coming from, there
are a ton of places. The WERE will tell you how to fix the problem. More than
likely you will need to pull the engine to fix. It could be a weep hole in the cylinder,
or a crack in the valve seat area....hard to seal with a "can of stuff". You need to
pressurize the block to find the leak. You could do this your self, disconnect the
radiator,plug the water inlet, make a plate for the water outlet, pull the pan,
fill the block with water and pump air in the plate on the water outlet.

Let us know, Dudley

Cracked block is a cracked block, still easy to found blocks, hate to rain on this but if the block is cracked bad it will always leaks, had a tractor one time and used something call liquid glass seems to hold, on a small weep, good luck with this al

One of my engine cores "appeared" to be a beauty...
Std bore, without your typical freeze cracks behind oil filler tube & even
some of the factory paint still intact

After a thorough hot tank cleaning I was horrified to discover a hairline crack in the valve chamber roof. I almost missed it and it only appeared in direct sunlight with the block upside down.

You might consider removing the side cover and look straight up into the area all around the valve guides using a mirror & flashlight. I'm not sure, but perhaps the hot water/steam will have "washed" the area?
If you're poking around I would plug the oil tube openings & blanket the inside with clean rags in order that no "crusties" get down into the babbit.

you can make a cheap pressure device with a motorcycle innertube. cut it and attach to the inlet and fill the enigine thro the outlet neck with water. clamp the tube tube on and pump it up. Dave

Thanks guys. I know that a crack will always be a crack however, I may try to get some pressure in the system and try again. One thing I did probably to cause it was to really gouge out the rust in the jacket when I had the head off. Probably opened up some old crack. In the meantime, I'll start looking for a new block. A spring swapmeet is comming up this month outside of Tacoma.
Thanks, Pete

If you are getting water in the oil pan, you probably have a bad head gasket or cracked block. Pull the head clean things up and see what gives.
