360 owners-HELP!

I have around 500 miles on a rebuild. The Jeep has been sitting for a week due to a broken alternator bracket. Last night after installing the alternator, I started the Jeep. I had a slight knock and a violent spray of oil from the filter. I thought I might have bumped the filter when tightening the alternator, so I changed the oil and filter. SAME THING! It blew oil in a stream from the filter seal clear across to the other side of the Jeep. On the first filter, the seam was blown out. The second one had the rubber seal expelled.
HELP! I need ideas...

Re: 360 owners-HELP!

just a guess, the pressure relief spring and valve are stuck

its that long tube on teh side of the oil pump coverplate with a nut on teh end, carefully unscrew it, see if its stuck, clean/lube and reinstall.

thats my only guess, maybe itll point you towards the problem

Re: 360 owners-HELP!

I had the opposite problem on a 500 mile enigine this Summer - turned it on and there was NO pressure. My pressure relief valve was apparently stuck open - I'm thinking yours is stuck closed just like Ozarkjeep said...

Re: 360 owners-HELP!

I think Ozark and Chuck are right on the mark with this one. I have had trouble from time to time getting the valve out of the cover plate on a couple of these. If this is the case and you can't get it out easily then remove the cover plate and it will be easier to get it out of there. If you have never installed a oil pump rebuild kit then just remember these couple of hints. Don't use RTV anywhere on the thing and use Vasaline to pack the drive gears and gasket so that they are held in place when reinstalling the cover when you fix the problem with the relief valve.
Hope this helps.

Re: 360 owners-HELP!

Thanks guys. I'll try that tonight!
Can you usually get the valve out without removing the cover?

Re: 360 owners-HELP!

It just depends on how bad or what is making the valve stick. The last one that I had to do I actually had to take the cover off and push the valve out with a piece of wire because it got stuck so bad.
Have you replaced your oil pump parts in a while??? If not this would be a good time to do it.

Re: 360 owners-HELP!

That was it! The relief valve was stuck, and I had to remove the cover to get it out. The plunger was scored slightly. After re-assembly, there are no more leaks, but I still have the knock! It seems louder under the Jeep. Could this have happened when the relief valve seized? The engine has power and good oil pressure, but the knock sounds ominous. Someone please tell me it's nothing to worry about...:-)
BTW, when I had the oil pump cover off, there were two circular patterns on the cover where the gears had been riding on the cover. Is this normal?? It seems like it would grind the cover away, or at least put metal in the system.

Re: 360 owners-HELP!

can you isolate the knock with the old broomstick to ear method ( watch the fan!)?

what weight oil are you running and whats the outside temp?

Re: 360 owners-HELP!

I tried that, and the knock appears to be coming from the bottom somewhere. It was the loudest when I had the screwdriver next to the drain plug on the oil pan. I can also hear it under the passanger-side valve cover, though not as loud as below.
Sorry! I'm running 10W-40 Pennzoil. My garage is around 40 degrees. (I had long-johns on!)

Re: 360 owners-HELP!

man, I dont know, but if it doesnt go away ( quickly) I would probably do some inspecting before driving much.

I guess maybe the oil pickup tube could have gotten moved, although Im not sure thats even possible on the amc setup. hmm

did it not knock before this stuck releif valve?

If the pressure is good, and its running normal I guess its ok, but Im scared of knocks.. maybe someone with more AMC knowledge has better help for you here.
