motor out of car now what

[slakjaw]

i am in the process of pulling the motor out of my 71 911 T
and i was wondering if it is a good idea to replace the oil pump while it is out. The car has low oil pressure when warm and i am not shure if this is normal for the older 911`s or if it is a sign of a worn out pump or just a worn out motor. The reason the motor is coming out is because the rear wheel bearings are being replaced but as long as it is out i wanted to know what else i should do to it.


thanks

you do know where it lives i assume? if an old engine is torn down that much, it's gonna be overhaul time. the pump gears are most likely scored, and the bearing clearances will likely be excessive on a high miler like that. a later pump is usually used in the process, for better pressure, and scavenging. it's an interesting project though, if you are so inclined.

Kyle, The oil pump is buried in the "bottom end". You have to take the engine all the way apart to get to it and replace it. The oil pressure will decrease on these engines as they warm and especially when they are warm at idle. Low oil pressure, if it is truly low, is likely more of indication of worn or incorrect size bearings than a worn oil pump. You really need to learn more about your engine before you proceed; you can really "screw things up" if you don't have the information and right tools. Get a shop manual and the spec. book for your year. Spend some time with this board. Things to do when the engine is out: adjust the valves, replace the engine mounted oil thermostat o-ring, replace breather cover gasket, replace oil pressure sender (if mounted on flywheel side of engine), replace old worn or brittle fuel and vacuum lines, take engine mounted oil cooler off and clean, replace it's seals. Remove shroud, clean cylinder and head cooling fins. If rear main seal is leaking remove flywheel and replace. To remove and replace the flywheel one needs the special metric triple square bit for the flywheel screws, and a big torque wrench to reinstall. Do not reuse the the flywheel screws - they're one time use only! Do a search of the archives; there's more. Good luck, Jim
