Water leaking around oil pan bolt on 59A
 

Why is this water leaking around this oil pan bolt and how can I stop it?

I just had to remove the oil pan to remove the fly wheel to get it resurfaced. Put it back on and now this water is coming out from under the bolt head. How can I seal it?

This one has me baffled there is absolutely no water in that area. Are you sure the water hasn't been spilt or leaked from somewhere above there and ran down and puddled around the bolt head? The water jacket doesn't come that far back around the bellhousing.

I agree. It's probably leaking from a head stud or maybe the head gasket.

I wish you all were right. I had just removed the radiator hose on the head on that side and put it back on and thought maybe it was coming out of there and running down so I just wiped everything off and started the engine and watched it seep up around that bolt head.

Definitely a mystery.

I guess I'll put some Permatex on the bolt threads and replace it and see if that stops it. Hope so. I'll let you know.

If anyone else had any ideas please share them.

Thanks for your help.

As said before, there is no water in the bellhousing casting. If it's coming from there, you probably have a REALLY cracked block. It would need to migrate all the way along that bottom surface of the block and seep up the bolt threads. Many other places for it to seep out as well. Can you see leakage coming out the bottom bellhousing hole, the one with the big cotter pin? Any water in the oil?

Henry, you sure have a lot of problems.
Like the others have said, no way is the water coming from the pan bolt.
Head gasket, head stud, or heater hose.

You have such a close up picture that I am not sure what I am looking at. Is this a front or rear of the pan?

Re: Water leaking around oil pan bolt on 59A
 

At the rear, just above the part of the pan that takes the starter. That's the transmission casing on the left. That's the bolt that was holding the pan on when it was initially being removed.

Like here?
Hope it's not because of the grade 8 bolt:)

Re: Water leaking around oil pan bolt on 59A
 

Yeah, that's it. (except that one isn't even there!). You can see how water can't get there without being spilt or leaking from somewhere above and running into it.

Subscribed!! I have got to see how this one plays out. We need you on the road. I miss the pictures of your travels.

Assuming the leak is not real slooow, why don't you remove that bolt (to slightly disrupt flow path), clean the area well by spray can, and just lie there with a good flashlight to observe what transpires?

Re: Water leaking around oil pan bolt on 59A
 

I tried repeating my test (wiped everything off and ran the engine again) and no water came out. Didn't change anything. So, hopefully, false alarm. Time will tell. I'll watch closely under the car (I've replaced the floor) for the next few days for any water.

Sorry to bother everyone.

What are you saying about the grade 8 bolt?

We will be doing an overnight road trip Friday to City of Rocks National Reserve in southern Idaho. http://www.nps.gov/ciro/index.htm

(This will be my 4th attempt. Hope we make it.)

Just in jest, I doubt that Old Henry ever had a bolt of that quality
in that spot when it was new. :)

Re: Water leaking around oil pan bolt on 59A
 

That's what Old Henry gets when I lose a bolt (like I do way too much) and rush down to Ace hardware and grab the closest thing to what I lost. He's probably got a lot of "overkill connectors".

Re: Water leaking around oil pan bolt on 59A
 

Could it not be the frost plugs in the pan rail seeping,running back through the gasket and the flywheel spinning it out there? My 40 deluxe had a similar problem.

Re: Water leaking around oil pan bolt on 59A
 

Frost plugs down there were not used after 1940 or thereabouts, so not an issue here.

Not familiar at all with a '48, but is the heater control valve right above there? Or the heater connections?
