No oil pressure on rebuilt 215
Posted by: 62Healeyhacker

Still zero oil pressure when I spin the pump through the distributor shaft. I have replaced the front cover and oil pump. What are the most likely causes? (I may have not gotten all the air out when I forced petroleum jelly into the pump.)

Also: I added the steel shim to bottom of pump to eliminate the wear problem. In doing so i made is impossible to change the oil filter without loosening a motor mount and lifting the engine a bit. ( i'm using the shortest filter that fits.) The pre'94 Rover V8 has a pump cover which faces directly forward. Yet I have never seen a 215 Buick using this. Any ideas? ( D and D doesn't list the swivel mounts on their website any longer.)

Any suggestions greatly appreciated.

How did you force the petroleum jelly into the pump? Did you take it apart & pack it?

It was done two years ago. I believe the new pump was installed in the new front cover after it was on the engine. I recall the difficulty
with the petroleum jelly because I was on my back in my garage.

Are you driving the distributor shaft/pump in the CW direction when priming?

Had a similar problem on a fresh rebuild once. Turned out the gasket on the pickup tube shifted and was covering the hole in the tube. Only one bolt went there the holes in the gasket. Pull the cover and repack the pump before you try anything else. Another trick is to over fill the sump with oil. The higher the oil level, the easier it is to lift the oil with the pump. Get it high enough and it will fill the pump on its own. Fill the filter with oil before you try and prime the pump.

Check that your oil pressure relief valve is assembled correctly. Mine wasn't.

Don't go by what is listed or not listed on D&D's website. Call them.

Few years ago replaced the gears in my pump, then same as you, couldn't get any pressure.
Turned out the paper cover gasket was too thick.
I got a replacement from ahhh, JE Engineering I think it was, that fixed it. Oil pressure in a couple of seconds with the drill.

As said, fill the filter first.

The petroleum jelly does dry out, needs to be packed well in.

Yes, the gasket sets the clearance between the gears & the housing.

Thanks for the multiple suggestions.
I have a hunch the gasket where the filler tube attaches leaks air. I will try that first. I hate to pull the cover again but may need to do it to check the pump to face clearance and to get fresh petroleum oil fully packed.

Yes I have been spinning the shaft clockwise. Got something right!

Here's what I have tried, without success.
I removed the filter and pump cover. With the gears down I packed the chamber with petroleum jelly. I loaded the shaft with jelly and the driven gear. Also stuffed the other gear with jelly. When I pushed them up into the chamber I wiped off the considerable excess petroleum jelly.
Using a "metric" pump cover from Silver-seal I screwed the cover and filter up tight.
Spinning the pump shaft drive clockwise I could feel the strain as the pump spun the jelly. I had high hopes that it was sucking through the pump then pushing the oil into the block. STILL NO PRESSURE!
I pulled the pan to check the gasket where the oil tube connects to the block. Not a problem.

I have ordered a new oil pan gasket.
Now what?

I recently primed my engine. I have never used jelly, simply ran a drill as long as it primes. This time it took quite long, maybe a minute or two. But primed anyway. I donīt know for how long you have tried but it may take some time.

I made an engine pre-luber out of an old brake pressure bleeder tank. Basically I put motor oil in it instead of brake fluid and then made an adapter fitting to connect where the oil pressure gauge sender (or pipe) attaches to the pump. Works well and pre-lubes the entire engine as well as priming the pump.

You could also use a speed-sprayer for that. I haven't, but it wouldn't be hard to do.

Please enlighten me. What is a speed sprayer?

Might be a specific store brand or manufacturer and picture was worth a thousand words. I have several different iterations in my shop. Thanks for the info and should be simple to adapt

I had to replace my front cover and now my engine only has about 25psi cold, previously I had about 70. I ran the pump with a drill until it sprayed oil out of the remote oil filter port. Could I be suffering from a priming issue? I did not know about packing the pump with jelly

New cover, or used?
I think you have to look at the pressure relief valve, and the clearances in the pump. Including, as I mentioned, the thickness of the cover gasket.
[www.v8wizard.com]
Unfortunately, he doesn't say what the thickness should be, but I do know that too thick destroys the pressure.

They prime easier with jelly, but once it's primed then it's down to clearances.

I did some reading and believe you are correct. It is a used cover with remote oil filter adapter plate.

This for Buick 225 V6, but should be the same or very close for the Buick/Olds/Rover aluminum V8s.
Quote:
The Specs for End Play clearance are .0023-.0058. Obviously tighter is better and I like to see them at .002-.004 max. T.A. Performance sells a gasket shim kit # TA-1704 that helps to attain those close specs. If the gear bore side walls are grooved or if worn to the point whereby the clearance between the gears and wall exceeds .006-.007 thousands it may be time to think about getting another timing cover.........Spec for side clearance is .003-.005.
