F 134

Looking for an F134.

 

I've heard rumors the people at Kaiserwillys have been developing new f134 blocks. If you can hold out a little bit, you might be able to build a brand new one. They have the heads ready to go currently.

 

Hmmmmm.....

Just incase....

 

The only F-134 heads I see on the KW site are reconditioned heads priced more than twice what others sell NOS heads.

 

5000 miles / 72 hr round trip for me to drive out and pick it up
...and it may have excessive crankshaft end play
... but... it may not!
Thanks for the lead, it's the only one I've seen in about a month of looking!!

 

Don't count on the rumor mentioned above. Kaiser Willys is a parts retailer, they do not "develop" things like engine blocks or heads.

For a little while they were selling new L-Head blocks with claims they were superior to originals.

They weren't.

Those were Asian imports and they got a lot of bad reviews because the blocks required significant machine work just to make them usable. If they were to market F-Head blocks I would expect the same source, and quality.

 

Well hold on to your hat cause this is available but just happens to be in switzerland haha.

Dang, I even like the color!
I just got back firm Switzerland (attended a wedding). This could have been my carry on "luggage"? No?
How about: "Emotional support.... engine"

 

I painted mine Detroit green too. Lol

Every once in a while a fully rebuilt one pops up somewhere. Otherwise, There are companies that specialize in rebuilding them.

Here's One I bookmarked a while ago. Can't speak to their work personally but I'm sure someone on here will have had dealings with them somehow.

Maybe it's time for a road trip out to sunny San Diego?

 

I have a daughter on the West coast, but 8 hours North of there (dang, CA is a LONG state). So... a road trip is actually a possibility... but only as a dead last resort.

 

I'm thinking of sharing our F135 overhaul here. Does the world need yet another thread describing a tear down, evaluation, and (hopefully) a restoration of an F134 engine?

My brother Joe and I got a good response to our previous MD Juan build story, and our canvas top sewing story seemed well received. We've never done an engine overhaul before so we would be presenting from a rookie perspective. Would our rookie F134 overhaul story be welcome here?

 

You should post whatever you do to your Jeep everywhere you can. Start a build thread here, as well as on OldWillysForum. Not only will you share your experience with others that can use it, you'll also get the collective experience from all the folks on the forums.
And c'mon, San Diego/O-side IS a Navy town!

 

We suspect damage but haven't opened it yet.

All of a sudden it started screaming when I started it A few months ago. I thought.."Generator bearing?, Water pump bearing?".

But I disconnected the belt and ran the engine for a few moments. The screaming continued. I watched the crankshaft pully turn. As it turned it seemed to shift towards and away from the face of the engine.

So, we measured the crankshaft endplay with a dial indicator and it moved over 0.040". The spec is (I think) 0.004 to 0.008. At 4x to 5x the specified allowable end play, plus it screaming like a wounded banshee, we figured something very bad was happening. That kind of endplay would put a lot of stress on the rod bearings, rods, piston pins, pistons, cylinder walls, thrust washer, etc.

With a Hail Mary, we retorqued the crankshaft nut - no change. Anticipating a teardown, we also checked compression: 135/125/125/115, plugs out, cold and dry. (3 years ago it was 135/135/135/135).

We were scheduled to be in a Veterans Day parade and figured, "Why not. If it screams we'll park it then tow it home". But It didn't make a sound and ran perfectly... until we got home, when it started screaming again.

The rough plan is to pull the engine and the oil pan, and check the crankshaft clearances at all the bearings, and see if there are any shims at the front. (I'm sure there won't be 16, which is hiw many we would need to remove to get end play back into spec!! ).

I've never opened any engine before, let alone an F134, but looking at photos and diagrams of others, it seems there has to be damage where the crankshaft hits the thrust flange on the main bearing, to explain that much motion. I'm dreaming that if a miracle occurs, the crank will be OK, and new set of main bearings might be "enough" to fix it. But, I'm not expecting a miracle...

There is also the thought that compression is decent (but it does suggest at least one head gasket leak between 2 and 3). A wet compression test may tell us more about rings vs. valves. This vehicle only runs 1000 to 2000 miles a year... maybe I can just do the bearings, and a new head gasket and cross my fingers for the next few years... and it may last longer than I will!

 

Well, tis the miracle season
But don't get too intimidated about opening up the bottom end, nothing magical about it. Grab an oil sample to see what's in there, and once you have the pan off, things will become obvious.
Just remember, the 134 is probably the heaviest "little" engine around; make sure you have a good lift and stand. Also, it gets a bit tricky separating the trans from the engine so do your reading and research before you start.

 

An F134 just showed up on line. "Was rebuilt and running before going into storage, a long time ago. Crankshaft will not rotate ,(with a socket on the crankshaft nut). I'm inclined to take a chance if not too expensive. I see people talking about getting frozen, neglected storage engines running all the time.
