you mean the crank bearings?

the guy i bought it from did the oilchange before i bought it and did use a fram filter along with mobile 1 5w 20 synthetic. the rear main has a slow drip as with most other 4.0 s that i have seen if i do the oil pump i will put a new rear main in. i have already done that with the mj. the mj oil pressure reads 75 psi when running cold and drops to 65ish when hot at speed and 40 at idle when warm.

my thoughts were to replace the pump first then i would know that i have good pressure regardless of the reading then the sender later if need be, but now I'm thinking of just changing the oil, maybe putting in some seafoam then changng the oil would be cheaper than a sender or pump, but a gamble either way you look at it

Ok just went out and started it cold and at idle when cold it sits right at 40 and at 3,000 rpm it goes to 50, So idk maybe just need different oil in it?? when hot the pressure will drop drasticly

I just bought a 1997 xj 4.0 auto and drove it 400 mi home. The guy I bought it from said he had just did an oil change and switched to synthetic 5w20... I know pretty light if you ask me even for winter, but whatever. On the drive home cruzin at 70mph I knoticed that the oil pressure seemed low reading between 30 and 40 at speed and dropping to like 15-20 at idle I was concered because in my MJ with the same engine it runs 50 at idle and 75 at speed when hot which I have never had any complaints about I run 10w30 blend in the MJ btw. I have had the xj for about three weeks and figured I would just do an oilchange and put in some 10w30 when the oil he had put in it was spent. Well now my oil pressure is like 5 psi at idle and maybe 10 when running down the road and I could smell oil cooking needless to say it is now parked untill I figure out what is wrong because I don't want to ruin the engine. I read somwhere on a post once that the pressure sending unit could cause faulse reading is there any way to tell if the sending unit is bad? I was also thinking about just putting a new high flow oilpump in because the rig has 161000mi on it so it couldn't hurt right? $80.00 bucks for the pump $30.00 for the sending unit what should I do any suggestions on how to figure out the problem, or advise on what you would do would be greatly appriciated i don't have alot of $$ thanks in advance. Us jeep freaks have to stick together! :help: p.s. I saw a mj parked at my work ill post a pic in the pub lol felt like a creap out in the parking lot at night taking a pic of someones mj :brows: :banana:

1997 4.0 il 2h-4l 4x4 its an auto the only thing that is powered is the mirrors :thumbsup: less to break. I have a shopping list of parts that are going to end up costing more than I paid for the thing. rear bumper hitch combo, front bumper winch combo, lift kit..... was thinking 4-5", wheels and tires roof rack.... fog lights am I missing anything? :drool: hmmm or maybe i should just go crazy with my MJ the xj will be my dd :doh: idk opinions? I will tell you this the xj will get bumpers and a roof rack for sure. any ideas for a rear bumper with a hitch built in pics? thanks :cheers:

I just went and checked mine...... lol its on right :thumbsup:

YESSSSSSSSSSSSSSSSSS :cheers: :cheers: :cheers: :dunce:
