The oil pan must be removed, to do this you must disconnect the engine mounts and raise the engine off the mounts as far as poss, then u can unbolt and remove the oil pan, the oil pump is then assessable inside the engine

I have a 1997 tj jeep that i had the head milled and i now have water in the oil again do i need a thicker head gasket or what?

First of all did you go through the right steps in doing the job? when the cylinder head is removed it is always my practice to take it to a shop and have it checked for cracks especially if the motor over heated then I'll have them do a valve job and milled as well. If you didnt have it checked for cracks it could be its cracked thus the water in the oil.I know it cost more money to have this done but it removes all doubt and alot less head aches in the long run as well as less labor.Next was the head torq sequence follwed as well as the torq specs. It is very important that these be follwed exactly other wise you will end up with water in your oil or in the cylinders. I will pause here and give you a chance to respond looking foward to hearing from you.

Loose rocker arms,does it have hydrolik lifters?or worn out cam shaft

I assume you have the 4.0L engine. Your rockers are probably worn out where they contact the rocker pivot. I have seen this several times. It is due to low oil pressure. Replacing the rockers and pivots will help the problem with noise, engine not running properly, etc. but it will only do it again unless the low oil pressure problem is fixed. It usually requires replacement of the oil pump to fix it. While the oil pump is being fixed, the main and rod bearings should also be checked. I have done a couple of these where the rockers were completely worn out but there was no apparent damage to the main and rod bearings. I have also done a couple where all the bearings were trashed as well.

Engine diagram 1997 jeep wrangler SE

So how do you know you need one if you dont know where it is?? Oil pumps rarely go bad unless the engine is sludged from lack of maintenence. After you take the oil pan off, its there hanging down. Make sure you clean or replace the pick up tube. I'm sure you can google up torque specs, for the bolts. Usually there is major engine damage by the time you figure out that there is lack of oil pressure. I would get a professionals opinion before you waste time and money replaicing the oil pump. If the engine has any unusual noise or knocking, its too late.

98 jeep tj 2.5 eng noisey lifter can it be ajusted

Lifters on your engine are non-adjustable. If noise is not loud or is intermittent, sometimes just changing oil and using an additive like marvel oil will clean it up.If noise persists, check pivot contact points on "bridge" that connects each pair of rocker arms together for wear.Replace if worn. disable the ignition system and have someone crank engine over. Observe that all rockers are going up and down the same distance. The ones to check are the ones that are not. If all is ok there, you must go deeper into engine and check lifters for end wear. If you find wear, lifter and camshaft must be replaced Sometimes if the ends are still in good condition, the lifter itself may have an internal problem.If that is the case, replace the lifter.
Before you begin, check oil pressure. A pressure of 15lbs or less is not acceptable.(warmed up, at idle) Pressure must be substantially higher both cold and hot. I recommend at least 30psi at idle hot, 40psi while driving. Lower pressures indicate serious wear on internal bearing surfaces. Replacing the oil pump may temporarily hide this problem but will not cure it!!!
Good luck
