Oil pressure problem
 

Replacing my oil pump this weekend, got the oil pan unbolted and ready to take out but having troubles with Clarence. I removed my started for a little more room, but the pan is still hitting my front axel And my trAns, been working on it for awhile an no results..... Any ideas would be helpful

Are you jacking it up from the unibody and letting the suspension droop?

Let me slip in here for a minute...Why are you changing your oil pump? Just curious.

+1 jack it up from the front axle then put jack stands under the boxy sections underneath along the sides and let the axle droop down,

Then what?

Unless you want to unbolt the axle you have to jack up the front end a whole bunch. When the it's jacked up a scary amount you can barely slide the oil pan past the front axle.

I would also like to know what led you to changing the oil pump.

Be amazed when the pan doesn't hit the front axle?

Who is Clarence? Can't you just ask him to leave?

:rofl:

welcome to Cf interesting 1st post..a few questions for you... if you do not mind...
what year is your Jeep?
What motor does it have? how many miles on it?
Why are you replacing your oil pump? They rarely go bad....

It's a 2000.
Has about 125000.
My oil preasure light was coming on, I replaced my sending unit thinking that would solve my problem. Didn't. So I replaced oil pump yesterday, seeing that a lot of forums and people I talked to said it was the oil pump, so did that and tried replacing my main rear seal. Tryed and could get it so a buddy said it would be fine just replacing bottom of the seal. Got it all back together and the oil preasure light went off again last night and my truck has a weird noise as I speed up.... Any help would be appreciated thanks fellow jeepers

Exactly same issue here with my '00 XJ
 

Should've read more ... there's no salvation ... rebuild or run till it blows
Mine has 165,XXX miles on it, and check gauge lights comes up after oil warms up, also dipstick level is way up while coolant disappears. My question is how can this engines run so strong still?

Yup, oil pumps rarely fail. Most likely your engine is worn out. Low oil pressure is a condition and not a function.....higher oil pressure has no effect on protecting an engine. If you are still getting oil to the rockers you are getting it everywhere else. Mine has 101k miles with 4 psi and runs fine.

Cracked head lol. Nice. Don't worry, it will develop problems as the coolant continues to displace oil and cause more bearing damage.

I love the "run-to-destruction" approach many forum members have.

Oh....Just run it until it fails/throws a rod through the crankcase, just get another bone yard motor to replace it. Or, simply rebuild it. On and on, ad nausium.

WTF.

Sorry but you have to realize something with the years late 99-2001 have head problems... the heads crack and mixes the oil and coolant... which destories the bottom end of the engine... you can either run it till it blows or rebuild it... it is not something you can save once the damage is that bad... most of the time it is caught to late to do anything about it... :brickwall:

If you actually use your Jeep, that's the only thought process that makes sense. We're not here doing antique restoration.

Its starting to get to that point soon it will be happening... it is happening with the full-size waggy.. it will happen to xj's one day 2... antique restoration that is...

I've been "Using" and maintaining my Cherokee since 1999. If you were aware of your surroundings you'd realize that all XJ owners are engaged in antique restoration. Some XJ's driven and maintained by our members are actually antiques by definition.

1999 VIN S XJ's don't have head problems. :icon_cheesygrin:

I have seen it... exetremely rare but they do exist....:whistling2:

I think you're confused between 1999 model year and 1999 build date. Some 2000 model years with the 0331 head were indeed assembled in 1999. However no 1999 model years have the 0331 head unless someone decided to put one on.

Indeed/Agreed.

I got fooled by looking at a XJ that I thought was a '98 because the sticker on the driver's door said manufactured 1998, and the old driver's mirror date trick - said 98. However, the VIN for the XJ was "X" in the 10th position which is a 1999 model year.

The 2000 XJ would have "Y" in the VIN 10th position for that model year, regardless of when the sticker said it was manufactured.

Back to his original question. On a stock jeep the axil will not hang low enough to remove the oil pan. I had to remove the motor mount bolts and jack the engine up about 3 inches to clear the axle. If the oil pressure is dropping when warm then the bearings are gone and it is time for a rebuild.

Also, if just letting the axle droop isn't enough, you can use a bottle jack between the axle and body.
