i recently lost oil pressure in my 1994 Z28 Camero so i did rod and main's and a new oil pump. I purged the pump and reinstalled the engine correctly started it up and still no pressure the oil pump shaft turns but still will not pick up oil pressure please help.

Is the pickup height correct?

Was it picking up oil when you were priming the pump that you could see?

 

no how do you do that it was but when i got out of work one morning it just had no pressure i thought it was the pump but i pulled the engine and put rods and mains and re installed i did the pump when i first bought it and hadno prob with it picking up oil. Please help. I heard of something with the distributer.

 

Your pump is driven by the oil pump drive gear assembly.. this bolts in under the intake manifold where a conventional SBC distributor driveshaft would end up going.

Did you pull the intake manifold and make sure this driveshaft is not broken for any reason? It is made of plastic and can break...

 

..plus you can use an oil pump primer tool while you have the intake off, to see if your pump is working...

 

no i didnt sir but can i look at that while the engine is still in the car or do i have to pull it out again???

 

Ya can pull the intake and pull the plastic OP drive out with the engine in the car. Just a lot of work but not as much as pulling it out again.
Ya might find something wrong with the cam gear too.

 

Like LR said.. can be done with the motor in the car.. no problems.

It's a pain but I've got intake manifold removal down to about 40 minutes now with it in the car

 

i know the oil pump shaft moves cause i put a socket on the front pulley and rotated the engine while i had the engine out and the shaft moved along with it? it was kind of funny how it lost it in the first place? cause wheni went to work it had fine oil pressure and when i got out of work it had none. Has anyone else ever heard of something happeneing like that and is there a solution? thanks
