Calling Rob Love or others with info... Jeep F-head engine

[David Dunlop]

Probably a long shot, Bob, but is your head gasket OK? Normal compression in all four cylinders?

Down to 4?


Number one should be on the bottom. Number 3 should be to the right of that, number four should be at the top, and number two is left of that.


Of course, it all will depend on where the oil pump got installed, but the photo below is pretty much the standard installation. With the 60 amp alternator, the single pin power supply connector will almost touch the alternator.


I'll check my own Jeep this morning and confirm the photo. Again, checking for compression and setting number one should do it.

If the timing is not the problem, then two things that I might add.

Make sure the plugs are dry. When they get soaked, they can act up. Pull them and you can dry them with a heat gun or light application of a propane torch.



Also, if you ran it on regular (ethanol) blend fuel last year, and that fuel was sitting in the carb, there are two little diaphragms on the carb that can get effected by the ethanol. They are held on with 4 screws each, and are on the front and back of the carb as it is located on the engine.



I have also seen crappy coils. The original autolite coils were good, but towards the end more and more of the stuff came from offshore. There were bad coils, and the caps had to have the holes enlarged to get them to fit in the covers. You can usually tell the bad caps as guys will have installed them with just 2 screws and the rotor will rub and break on the now offset cap.



I still think that your timing is the problem.



In all my years, I did see one engine break the phonelic timing gear under the front cover. But that was rare in my books. It was on an in-service Jeep at that. I used to hoard all Jeep parts back then, and the repair was done in about an hour or two. I worked faster back then....today that would likely be an all day event.

Hi David

Engine is military rebuilt and ran perfectly while sitting in the crate 6 months ago??????

You picture with the wire location is DIFFERENT..........

The answer is probably right there.......

I worked with the dizzy cap with the plug wires still on and never questioned their location as that is how, presumably they wereleft by the owner when he took them off the old engine.

In a nut shell.....my number one wire is where you have the number 4 and my number 4 is where the number one appears on your picture.......

We have been trying to start it 180 degrees out of sync........

Even the photograph of the dizzy he took as he was taking it apart shows the 180 out of sequence....... we have been setting the BTDC on the exhaust stroke.......

Will pull out the dizzy....turnt he engine to BTDC and re insert the dizzy whcih should index in the same position you showed in your picture.

Then find a hammer and take turns hitting ourselves over the head to the tune of the roaring engine.

How you a large beer and St Hubert chicken........
