I have a 93 grand Jeep Cherokee Laradeo ,to change the oil pan seal , and or the oil filter housing to change the O rings , or the timing cover seal or the rear seal , dose one need too lift up or pull the engine ? I have a oil leak up there some where.....thank you Richard

If there was no noise when it went to zero I would replace the sending unit by the oil filter for a few dollars. If it is a light ticking and it is all the time I would replace the bad lifter but if it is more clanking or thumping you have problems. If you disconnect one plug wire at a time and run it for a few seconds and the noise goes away that cylinder has a bad connecting rod bearing. I would pull the oil pan and replace the bearing. Or just replace crank and connecting rod bearings and get rid of it

hate to say it, but sounds like a blown gasket or cracked head - the mere indication of the white mily substance.
If you haven't done so, it is time to do a compression test.
Alternatively have you checked your oil pump itself?
Best regards

could be the rear main crankshaft seal

front & rear seal oil pan ,crank seal,vavle covers,oil pan gasket..

locate oil drain plug on oil pan,engine off. take out oil plug with wrench, drain oil into a big pan or similar. when oil is drained remove oil filter and put new one on, put some new oil on filter seal with finger then screw on to car as tight as you can get it by hand. do not use a fiter wrench to tighten filter only hand tight. use oil filter wrench to take off old oil filter. when filter is on put plug back in oil pan and tighten. then add your new oil to reccomended oil level.

Three ways to check:
first: check if the shift cable is in position, cick down cable too..
-next: check if the torque converter is connected to the engine.
- remove the oil pan from the auto trans and check if the oil filter is in place. If you look to the right front side of the tranny, you see a lid with a coil spring in it. check if the spring is ok.
- if tranny is open, check for metal pieces or clutch material in the oil pan and the filter unit. If you find more than usual, replace the transmission.

get a normal oil filter if oil "O" ring leaks You may have an obstruction on Your oil pressure

there is a oring between the block and the filter housing. be carful because changing that oring is a pain kdc744

If I remember correctly that adapter housing has 3 o-rings, 1 big one for the housing and 2 small ones for the bolt that holds the housing on.

I'm assuming you are talking about gear oil for the differentials. It's the pumpkin shaped thing on the axles. If you want to change the oil, loosen up the bolts with a drain pan underneath it. Clean the mating surfaces of the differential cover/housing and apply RTV to seal it. There should be a rubber grommet toward the top of the pumpkin, remove it after everything is sealed and fill to bottom of hole. That's how I do my '93, anyways. Some call for friction modifiers to be added to the gear oil, keep that in mind too. It should be in your manual.
