F134 Oil Filter Inlet Hose

Should the Oil Filter Inlet Hose screw directly into the engine head, or is there a fitting in between? Mine will not thread directly in, and the PO has some fitting that doesnt fit the hose and needs a second fitting to fit correctly... and its leaking pretty bad...

Mine goes in close to the top and out at the bottom of the filter canister.

 

Comes out near oil pump, as others have said. And yes, there is a fitting from 1/8 pipe to flare, to match the flare on the hose. If you're just jamming the flare into a hole threaded for 1/8 inch pipe, not only are you going to destroy the threads in the block, it will never seal as the flare has nothing to seat against. The new reproduction hoses are too tight of a fit against the fuel pump, and I have had one blow out near the filter. I plumbed the whole thing with 1/8 inch pipe using steel fittings and a hydraulic hose. Not factory routing, but peace of mind now. Any industrial supply shop can set you up. And yes, no matter how hard you try, you will have to remove the fuel pump to gain decent access. It's not worth trying to work around it.

 

IIRC, would that not be inverted flare? Same or similar to brake fittings?

 

Is that correct?

And while we're at it.. whats with the red tub coming out of the valve spring cover? Does everyone else have that?

 

If you have a '54 engine in your '54 Frankenjeep, that tube is correct for the year. Gets replaced with the PCV setup in '59 or '60. The PCV system was developed for military jeeps for stream and river crossing without bridges.

 

Those old style crankcase vents are called "road draught tubes" and were supposed to help pull the crankcase fumes out as you drove. They often were a source of oil drips too. They were the clean-air folks nightmare.

IIRC the road draft tube came on pickups and wagons, while all CJ's had a PCV system.

 

I had a '55 CJ5 once that just had the open tube. I can't say for sure the engine or tappet cover were original, but they looked unmolested. All I ever did was a fresh water pump and adjust the valves.

Military got the PCV system. CJ's not until late '50's or early '60's. For F-head engines. I don't believe there was any room for them on the L-heads. Both exhaust and intake were both mounted on the drivers side covering where the PCV mounts. PCV was actually developed for deep water fording, which is why the M38A1 engines got it. Closed system with a snorkel up in the air and a tailpipe extension to the same height.
CJ's didn't need that.

 

Well, I don't know. My MB had a PCV valve mounted on the tappet cover and it's been several decades since I've seen it. I should have kept that service manual.

 

PCV or deep water fording valve?

The 3B page 8 shows the little bell connection on the forward cover, right by the fuel pump.

On my engine the little bell connection is on the rear cover. That "T" that is at the front drivers side corner of the block is plumbed around to just behind the pump location, with a longer tube running to the rear for the PCV connection. Mine may have come with a governor mounted on the front drivers side of the block. I have extra mounting adapters there, and a different bell-crank for the throttle foot-feed system that would have been connected to the governor. The '60 used to have something really heavy mounted in the rear. There is a large hole there that some PO has covered over with another sheet of metal, really heavy-duty springs on the rear and also had an extra set of coil springs mounted between the rear axle and the frame. Maybe a ditch digger or an auger for drilling wells.

 

The M38A1-C came with coils and extra heavy leaf springs too, if that possibly is any clue to your parts.

But now we are a long way from the oil filter!

 

I was actually speculating on why my PCV bell is on the rear cover instead of the front one.
