Topic: fuel filter swap

He has no oil pressure at Idle. But did say when he reved it it came up to 40 then went back down.  Me I would put on a mechanical gauge and make sure.

  Also just thought of this is there not a problem with mixing YJ and XJ gauges and sending units.  Think I read about this on another place while searching the web.

I think I have the sending unit off of the 88 but I do still have the YJ gauges.  I know I have some pressure because by mistake we started it without the filter on (someone moved a tad bit to fast) and it blew out all the oil.  I would think if there was no pressure none would have come out.  I am going to find someone with a tester so we can manually test it, and do a compression test as well.

Does the XJ have an oil light and not a gauge?

[bammerman]

Well the gauges I got from it were aftermarket I believe. I went to try to hook it up to the YJ ones and there were no wires.  need to look into my electrical book and see if it is possible.

Not sure if.this is normal but my head gasket looks to be made out of cork and is almost a 1/4 thick. All the ones I have seen are not cork. Is this a normal practice?

cyl head gasket?
they are not made out of cork, post some pictures
they are not 1/4'' thick either so that's a red flag regardless.

who rebuilt the engine?

[bammerman]

I will take some pictures when I get off of work.

Valve covers or heads?  How are you able to see the gasket for the heads?

i'm assuming he removed the head, it did cross my mind that would be the valve cover gasket but then i thought the head gasket is pretty specific

[bammerman]

This is the location that I can see cork, I think. Going to take an exact picture when I get home.

here's a thought: what oil pressure sender do you have on that motor? did you put your's in there or it's the one that came with it - they are different between certain years

[bammerman]

I do not remember that was almost a year ago.  I can take a picture if that will help too. I am leaving to go home now

i'd say just put a mechanical gauge on it that will give you the answer right away, my guess is that is the wrong sender (doesn't make sense to go 40psi revved and 0 at idle, would be really noisy in that case).

My new mechanic is coming over tomorrow or next day to pressure test it.  Here is the gasket I was talking about - shit looks like wood.

I'm going to guess it's a reinforced composite and not cork.  If you really don't trust the work done to the engine, pull it apart and assemble it yourself.
