Info needed: for a 13-3-53 CDN Jeep

[BCA]

Bob: The date is unusual. You say 13-3-53 however the typical format was Month-Day-Year. Is this M38A1CDN possibly 3-13-53 ? Any chance you know the Ford serial F-xxxxx.

Hi David

Never ran it long enough to get hot ...... within 5 or so minutes the oil pressure started to go to zero so it was turned off........ however in its present location I would be really concerned for fuel to boil/vapor or melt the plastic housing of the filter.

On the dates.... yes you are correct Brian.... it is March 13 53..... where will I find the engine serial number??? not sure the engine is original of the 53 jeep???? will the engine serial be on the data plate...?

All the data plates are on the dash but very difficult to read partly worn and bad eyes..... best to HiRez photograph then play with photoshop to make out the faint lettering/stampings.

Thanks

Hi Bob , take a couple of photos of the engine area and send them to cckw353@bell.net , then call me,

Will do Frank probably tomorrow.....

Thanks

Found a lot of very useful information on the web......history of the Hurricane and specs..... numerous forums discussing low oil pressure and sludge build up...... and lots of pictures helping me sort out the filter connection and solution for the one oil leak we noticed at the block where the line exits to go to the filter...... well hidden behind the two stage fuel pump.

Will try to take pictures of the actual jeep in question tomorrow.

Grant is doing a search of his technical book library.

I can see someone falling in love ( not me.... not me) with the cute little thing....after slugging on the CMP oversized parts....... the bare power train pictures of a jeep is cute and cuddly.... makes you want to pick it up and burp it!!!!!

My preliminary plan of action...........

A... install a mechanical oil pressure gauge and see the results......

B....followed by changing the oil pump (owner already has a new one).......all hoping to save the engine from a tear down.

Cheers

In my limited experience, the F-head engine gave about 15000 to 20,000 good miles, followed by about 15,000 bad miles and then you replaced the engine. I was going to suggest a mechanical gauge, but I see you've already figured that out.

One of the weaknesses of the Jeep blocks is that there is only one replaceable bearing for the cam. The remainder of the cam supports are the block itself, which means any wear in that location will not be fixed by merely turning the crank, new bearings, and replacing the one cam bearing.

That said, oil pressure is highly overrated. I worked on one engine recently where the owner had the motor rebuilt, but could get no real oil pressure reading. They changed the sending unit, then changed the gauge, then changed the sending unit....

Anyway, going along on the highway, the engine suddenly seized up solid. When I tor it down, I found that the re-builder had neglected to put the front oil nozzle back in (sprays oil against the timing gears), thus leaving a 3/8 hole wide open on the main oil gallery. And yet, the engine had survived several years like that.

If it does come to a teardown, they are a great little engine to work on. I used to do them in my basement back in the old days. The problem was getting the finished product back up the stairs.

The fuel line does indeed run across the front of the engine, then up and across to the carb. My guess is it keeps the line away form the exhaust manifold. Personally, I have never had an issue with vapour lock on the Jeeps. Best place for the filter is down at the frame before the fuel pump.

Thanks Rob.

We have a spare 24v sending unit as well as a mechanical oil guage to start with...... then we will tackle the pump replacement.

At 61K on the clock, assuming it is the original block, it may be tired.

Thanks for the tips.....will post results.
