Hey fellow Willys fans.

I appreciate the responses and ideas, but 30 minutes after Bills post, I welded in the gap. �I wouldn't have been able to sleep otherwise. �It turned out great. �The hole is sealed. �For extra measure, I used a little gasket maker. �

Bill, you may be home now and have already looked at yours, but here is what is behind the plate in that area...air.



Have I mentioned how much I like this forum?

Hi guys, I'm no whiz bang at this stuff, but I think I might be tempted to use some black RTV gasket material, its heat tolerant and has a pretty high tensile strength.  We are dealing with no pressure here, just splashes.  i think I'd be tempted to apply it into the hole from the front, put enough in to blob up on the back side and plug the front flush.  It cures overnight and locks up tight.  If it doesnt work, nothing lost and no damage done.

Just a thought, wheres' the picnic?

I am in Tulsa, and might make it to Iowa by the weekend.. I miss those shows back East...

Ever take off an old timing cover that uses a full sheet gasket and notice how the paper curls up and away from the block where it is not securely held in ? I forget what engines I used to work on that did that..That's the kind of "blowout" I am referring to, just heat and oil fumes over time causing the gasket to warp out of position...Or an enthusiastic steam cleaner wand doing the same thing.  Failure might occur years down the road, and you are right, probably will work in most instances the way you suggested. But on my own stuff, Murphy loves to show his ugly face and anything I can do to get him outathere is a good thing.  ;)

Enjoy the show, say hi to Bob W and the gang for me..

Hey no offence taken. I simply have a difference of opinion with the method, that's all. As you say there is no pressure in the chamber so I don't see the concern over it "blowing out". However, I would also suggest that the owner do what he feels gives him that warm and fuzzy feeling after it's all said and done. �:)

By the way, you making it to the Picnic this Sunday?

I wouldn't trust any normal gasket material to not deteriorate over time and blow out there without support from both sides.. SUppose someone pressure washes the engine in that spot a few years down the road....Besides, there is already a gasket there behind the plate...just nothing for it to seal against.

The reman engines we used to get from a very reputable source often had things like valve cover gasket rails built up with some sort of JB weld type of epoxy...Never had a problem with them. I suppose they found it economical for fixing junkyard damage on the cores they were buying. These were for late model 90's cars and trucks... If you built the block up with some JB or devcon, above the block that shows behind the plate in the hole we are talking about, and flat filed the front sealing surface, I guess it would be a fairly simple, no weld fix.

All goes to show there are several ways to approach the same problem...Aplogies to Rocketeer if I offended with my over caution.  :-[

This clearly shows the two different front plate gaskets, you will need to use the one with the round hole and do whatever it takes to seal it, JB weld on the block, silicone, solder in a patch in the plate, braze the plate, or weld it. I don't think Larry's idea will work in this case but MAYBE a heavier plate installed behind there to seal to the gasket might.. Ag least we aren't dealing with oil under pressure in that area.
So if we're not dealing with oil under pressure, and we aren't, why won't a gasket work for that tiny little opening? If there's a real concern then back up the gasket with some silicone sealer behind it but JB Weld and brazing are, in my opinion, extreme measures for a simple problem.

I'd still want to add someting to seal that hole, unless it is a hole to nowhere...Being on the road I don't have a gear drive block here to look at....what is behind the plate? You could use JB weld, silicone, etc....

Before I would go brazing that plate, here's what I would do. I would make a thin gasket as outlined in red below. Coat both sides with a thin coat of Permatex and put it between the plate and block. The four holes will tighten it in place. I would back up the two upper holes with flat washers on the back side so the gasket doesn't get damaged when thightening the bolts.

Man am I on that Trail as well, with some luck I think I may have made it to the "otherside".  Just empty every pocket, just eat every penny.  JEEP

Yes, but think of all the "Honey, we aren't gonna spend the night here in the woods because the jeep broke again" moments you are avoiding by doing it right... ;)

Welcome to the Willys world!  We all survived it-- with help from the rest of the members, and maybe laying on a couch babbling things about our childhood, etc. Now we are all better people for it, and we can escape when we want in our Willys.  Jim
PS nice looking flatfender!
