The side cavities of the cap are filled with RTV sealer. Once loose, the bearing cap is more than likely going to stay "stuck" in place. It is helpful to have a breaker bar to get these bolts loose. The torque spec for the rear main cap bolts is 100 lb/ft.If they do, you will lose oil pressure and your engine soon after!!! Factory torque spec is 96 inch/lbs (or 8 ft/lbs.) Apply loctite thread sealer to the oil pump pickup bolts. REPLACE the gasket that goes between the block and pick up.
You may find your old rear main seal on the bottom of the screen!!! *IF* the screen looks like it needs cleaning or is all clogged up, remove it and clean it. As a last resort, removing the pickup tube guarantees that the pan will come off. Removal of the converter dust shield may also provide more clearance. If you have trouble removing the pan, try rotating the engine to get the counterweights out of the way. This one can be a real pain to get off (try using an open end wrench.) There is a baffle in the oil pan and it can hang up on the oil pickup screen. There is one bolt on the passenger side that secures a clamp that holds the tranny lines. The three bolts at the front of the pan are smaller (10mm) than all the others. Locate the jack at the front of the transmission pan. If you do need to jack up the engine use a block of wood (piece of 2x4) between the engine and the jack. Some guys have used their engine tie down to rock the engine over to one side. Depending on you car, you may or may not need to lift one side of the engine to get the pan off. Drain Oil, remove crossover pipe and oil pan.Piece of stiff sold copper wire-plastic coated is O.K.Small screwdriver and/or putty knife to clean off old RTV sealer.Torque wrench (1/2" drive, 0 to 150 lb/ft min).1/4" drive ratchet, 1/2" & 7/16" socket for oil pan bolts.1/2" drive ratchet, 5/8" socket for rear main cap bolts use a 6-point socket on rear main cap bolts!!!.Black or Ultra-Black, O2 sensor safe RTV Sealer.All attempts have been made include everything needed.
Despite the numerous steps below, the job is not hard to do if you just take your time. You'll also want to set aside several hours for this job as it is a good idea A) to make sure everything is clean and B) to give the RTV sealer used in the main cap side cavities time to cure. A good time to do the rear main seal is during an oil change as you have to drain the oil anyway.
