Ok here goes. first off... its a pain in the a$$ job that requires patience and a bit of arm strength. 95 xj btw
oh and your working with about 1 1/2 inches of clearance between the bolt and the frame
what you will need... grinder. T60 torx bit. vice grips. BFH. carb or brake parts cleaner. new oil filter. new oil filter housing o ring gaskets (had to get them from a dealer as n autoparts store has them)
first. wearing safety glasses of course. you must grind a flat on either side of the torx bit as nobody in the tidewater area has any clue what your talkin about and cant sell you the right part....... anyways. thats where the vice grips come in. put them on with a force over the flats to ensure that there wont be any slippage.
that would be the desired bolt. this is from the underside. its impossible to get to from the top.
attach the vice grips to the grinded torx bit and make doubly sure that the bit is in the hole very tighly and take an 18mm wrench lik shown above and pull as hard as you can tobreak the bolt loose. its a b!tch.
after you get it off. remove the filter and knock out this center bolt with your BFH.
these are the old gaskets. they looked and felt absolutely fine. looking at it now i believe it was my old oil filter. it was some how smashed and dented.
that cant be safe haha it was most likely the problem but more experience is always welcomed here. so for future reference always replace the filter first and if the problem persists then move one to the housing.
retaining bolt. where you place the gaskets is pretty self explanatory. small one in the middle of the bolt. medium one on the top section. and large one on the housing itself. and as always make sure all gasket surfaces are clean and use a bead of oil to keep the large gasket in place upon putting it back in.
new gaskets from thedealer as no one else sells them.
ok so thats a pretty basic walk through. if you have anymore questions please PM me. oh and a good tip when loosening or startig the bolt. spin the whole housing and bolt. then hold the bolt and do it again. i hope that makes sense to you like it did me. good luck
