any one ever tried this?
i pulled a 302 engine from a 79 f100 that i bought a few months back and according to the work order receite i received with the truck its only got 30.000 miles but was informed about a bad oil leak from the rear it used 8ltrs of oil to go 160 miles so its leaking bad! i have never seen a rear seal leak that bad so i am thinking more of the rear cam/oil gallery plugs as there is a bunch of silocone on all of them and that area was realy wet if i removed the dist would a drill and a socket turn the oil pump fast enough with enough oil pressure to see any leaks that might be there? i have the engine on a stand and will re & re the pan anyways to replace the rear seal and sheck the bearings but would hate to re install it again to have the same problem or would any one hae a better idea?

you have to have the oil pumped up to the heads to get oil in every galley , if you use just a long drive on the drill then you wont pump oil to the heads ! there is a tool that will let you do that though ,

well i asked an old mech freind and used a 1/4" deep socket/extension with a drill and it worked fine i installed a mechanical oil pressure gauge and got 40 lbs oil pressure no leaks used a 1 burner propane camping stove to heat the oil still no leaks then i dropped the extension into the oil pan! no big deal pulled the pan and rear main cap seal was toast so i hope thats it but found the oil a greenish milky color my 1st instinked would be coolant but the rad never went down a all on the trip home so i am sorrta stumpd i will pull the heads and inspect that area and put all new gaskets but one thing i did notice the pcv port on the carb was plugged off with a rubber hose/bolt/clamp if that was not working i am thinking it could pressure up the crank case enought to cause a leak on the seal

Plugged PCV will do that. The blow-by and expansion with heat has to go somewhere and pushing oil out of a leaking gasket is definitely a way to reduce pressure. Gaskets are cheap and easy to replace when the engine is out. If they are questionable, just replace them.
Just a thought... but your oil may be goofy colors because of internal condensation not being able to evaporate and not being sucked out by the disabled PCV system. Or you may have a minor internal coolant leak. You said you are pulling the heads so be sure to check the coolant crossover ports in the intake, that's usually where they start to leak a bit.
Good luck with the project!
