Okay we need some help on my brother's engine. Does anyone have a write up or can help me out on how to prime the oil pump on an LT1? Thanks ahead for the help!

 

Only way I know of is to pull fuel pump fuse, pull spark plugs and crank away.

 

yep or pull the injector wiring to the ecu out and the coil and crank away

 

How long do you crank on it? Sorry to sound dumb just never done it before

 

Just watch the oil pressure gauge in the car. Should start building after 3-5 sec.I just pull the to 7.5 amp injector fuses.

 

it will get up to 40+psi. just pull the fuses.

 

whats the point in turning the engine over to pre lube it? i thought the point was to make the oil pump lube the engine before its turned over. ive always heard "take the intake off and manually rotate the oil pump", i believe thats the best way.

 

well, being that everything should be covered in assembly lube/cam lube, a few revolutions to build oil pressure is fine. it is alot different then starting the motor.

 

To me this is a very accurate statement.

When I rebuilt my 350 for my truck when I was assembling it I ensure every surface got lubed, and I primed the oil pump but if I hadn't primed it I still think it would have been fine.

With the LT1 you still prime it from the top but with the intake off right??
