what should i do?

Home  \  Repairs & Maintenance  \  what should i do?

my friend has a 93 ford escort (piece of sh**)
he doesnt know anythin about cars except how to drive
something caused the oil pressure to drop significantly enough until the bearings all took a dump there was a loud distinct lower internal knock somethin that wont go away with proper oil flo
so i tore the engine apart (i have never even seen the inside of a ford motor)
besides all the tolerances being funky everythin looked good for a small engine overhaul so i changed all the rings and bearings and since the #4 piston was beat all to hell i got him all 4 new pistons and had the rods reconditioned along with pressing the wrist pins i honed the cylinders oddly enough all the tolerances were perfect stock on the cylinders and the krankshaft all the ware was from the bearings all new gaskets also i didnt do anything else in other words i didnt check the cam none of the valves or valve stems were replaced visualy checked but nothin else everything looked great i put it all back together and started it at first it was ok but then oil pressure droped again and i have an obnoxious valve clatter now ive heard 2 solutions so far from people who actually looked and heard the engine 1 is i should have checked the cam 2 is faulty oil pump
the oil pump that is on now is brand new and the concept is simple enough i dont see why it would not have good pressure
i have been doin my own research and i remembered a post from a ford mechanic about a pontiac the oil pump and sending unit i gave him a suggestion. now in his post i remember him sayin that if the oil sending unit in a ford is faulty there will be valve clatter
i dont know how far off i am but i can tell u this for sure after running it for a few hours to break in the seals and stuff i pulled the oil filter off and there was no oil in the filter indicating there is insufficient oil pressure
please any help will be much appreciated.........

so you spent all this money and didn't spend the extra 40-80$ for a new oil pump now those new bearing and rings are scored groved etc (garbage)
do it all over again and replace the pump i'm very surprized that it actully ran fo a FEW HOURS chalk it up as a big learning experience for rebuilding engines
you spend that much on new part whats an extra couple of bucks for the oil pump good luck next time

ok sorry i went on the info given
did you prime the oil pump(fill the cavity with petroleum jelly)if not you could try filling the oil filter with oil put it back on and retry the major damage has been done other than that take the oil pump off and pack it through the pick up tube hole not the tube itself

if the oil filter prime does not work you need to fill the pickup tube hole in the pic with petroleum jelly pack it in full

could i pack it from the oil filter end instead so i dont have to take everything apart?

i dont think so as its the outlet the oil would have a better chance to flow into the pump and down to the pick up tube
