I have a 93 grand cherokee, 4.0, the oil filter adapter o ring is leaking. i've went to my local dealer to get the parts and look at a diagram of it, but the pics i saw don't match my unit, can anyone help me find out how to repair this. i can't afford to put it in the shop. thanks
What size is the removal tool for the bolt on the '93 grand cherokee oil filter adapter
I have a 93 cherokee, I just did the o ring replacement..mine is a canadian made jeep so It had a 9/16 hex nut...I bought a 9/16 hex L wrench (allen wrench) at napa for around 7 bucks...I cut a small chunk (about an inch) off the long end...got a 9/16 ratchet wrench and a piece of aluminum pipe (about 2 foot long)...spray the area good with pb blaster...it should loosen the bolt up....I left my oil filter (vertical) on and removed the filter and the adaptor...my bolt o rings were still good so they got left on..replaced the adaptor o ring oiled the bolt ...put it back together...no more oil leak whatsoever...another part you may want to replace is the oil sensor, oil fill cap, and valve cover gasket while your at it...if the sensor is bad the oil will come out the back of the plug area... change your oil ALL SHOULD BE GOOD...
It is a t-60 torx bit. u have to use a breaker bar loosen motor mounts and tranny mount .remove pass. side bolt useing a block of wood and a floor jack lift the motor just slightly to get to the bolt. it is a tight fit but it can be done.replace the oring put it all back together goodluck!!! .

The oil filter housing and the timing cover can all be worked on with engine in car. For the rear engine seal (rear main seal), the transfer case and transmission will have to be removed to access the seal. Most of the time, the oil pan can be removed without raising the engine. Check your clearance under there for anything obstructing removal. (I loaned out my Jeep manual and never got it back!) On some cars, engine needs to be raised about 4 inches for pan to clear the oil pickup tube. Don't know about your Jeep.
Ok you can disassemble the oil filter and loosen the bolts that
connect the basis of the filter to block and this is a board of rubber or ring
that is the one that sealed with the time, this is crystallizing that is why you
leakage of oil by that there is a good seal. Thanks
It is very hard to turn, but it will come loose, a cut off allen wrench attached to a pipe works great, as there is no clearance to do it any other way. Have at it cause the allen bolt is pretty hefty.
I am an "x" mechanic and had the same problem with my 94 jeep grand.
This is an adapter block that connects to you engine. The chrysler designer didn't leave enough room to put on an oil filter so the put a 90 deg bracket on to miss the frame.
At the end of this adapter you will see a ,large looking bolt with a star insert. This is called a torx. I will have to look tonight but my memory is saying it is a 20x torx. The problem is the std torx socket is to long. 2-3" you only have 1-1/2" to get torx and ratchet between frame and adapter. I modified a std torx to be shorter. You insert into a 3/8 ratchet and put a small pipe on ratchet. This give more leverage. This torx bolt is very tight.
It is easer to remove from the bottom of car. Once it is loose you can remove oil filter first before doing or just leave oilf filter on the bracket. be shore to dump out oil before remounting bracket. There are two o'rings between engine and bracket. From the heat crack making the oil filter look like it is leaking. My engine starter was always wet with oil. After I replaced the o'rings it has never leaked again. I also saw oil leaking from my oil switch. I replaced it also. The chrysler dealer had the o'rings apprx $3.00. 1 large and one small for bolt I bought the oil sensor from Salvo's $15.00
Or you need to take to dealer.
Yes you are not crazy!. It is really leaking there.
There is an "O" ring between the Oil filter housing and the adapter that will leak as well. Remove the oil filter and check inside of the housing for a large nut. Remove the nut and separate the adapter from the housing. Check the "o" ring between them and replace with new "o" ring. That's where mine is leaking and I've read a couple of others that had the same problem. The old ring started out "round" and has, over time, become flat. The new ring should start out with a flatter cross section that will seal better. Good luck! (Easy Fix, but finding the "o" ring may be a challenge. Check for the ring at the Honda Dealer as the Passport is the same basic vehicle.) Do it during the next oil change........
common oil leak on those vehicles is the "quick connects" where the oil lines go into the oil cooler (what i believe you are calling the "doble") replace the o-rings on the quick connects for the lines
