thanks for all the info i do have another motor that i know runs and makes oil psi to put in it and ill rebuild this one at a later date
When you do your rebuild,
Pay particular attention to the rods and mains. Keep the tolerances TIGHT!
These are bearings you CAN do something about the amount of oil volume they hemorrhage.
I won't put one together without putting in an oil tube from front to rear of the engine block.
Just makes the engine live SO MUCH LONGER you wouldn't believe it!
Anytime you have the front cover off an AMC engine,
Take the intake off too (not very difficult) and replace the front camshaft bearing.
You can do this without having to open the bottom end of the engine, and a fresh front cam shaft bearing will save you a ton of oil volume loss.
People just don't realize how much of a beating that front bearing takes with the accessory drives on it, and then add in a sloppy drive chain, and things REALLY go to he!! in a hurry!
There are a few tricks you can do for the front pump and front timing cover that will help oiling in the long haul...
One is to make sure the passages line up!
You wouldn't believe how misaligned the passages from front cover/pump can be to the block!
Internal passages in the front cover are a good place to start opening some ports up for volume...
There are a couple of passages that are WAY TOO SMALL and create a restriction for the POTENTIAL oil volume that can never leave the pump chamber!
Check for oversize lifter bores when the intake is off.
Sometimes they get wallowed out and drool a BUNCH of oil volume.
Just stuff like that when you are ready for rebuild!
If you shut the engine down now, you will save the rear rods and crankshaft journal...
#7 & #8 rods like to dry out the most (Furthest back in the oiling lineup) and wipe out the crankshaft...
You WILL NOT see it coming, just one day, you will get a 'Knock' that will get louder and the engine will loose power.
When you disassemble, you will find the bearings hammered out of the rods,
The rods will be wiped out and non reusable,
And that journal on the crankshaft will be ruined, usually ruining the crankshaft entirely.
Usually when #7 & #8 rods oil escapes (hemorrhages) out,
#4 & #5 Main Caps usually don't get enough oil, and they often go when #7 & #8 rods do.
This not only will seal the fate of the crankshaft,
but it will ruin the block for all intents and purposes also...
That is, if by the time the rods fail enough to let you know, you haven't broken one of the cast iron rods and wiped out a cylinder or main web in the block...
