Reposting from the What did you do today......


I’m in the process of installing my new oil pump gear set. I disassembled the oil pump pressure relief valve assembly for cleaning.

The shown parts below in picture one are the snap ring, cup with o-ring,spring and relief valve. Visible when the oil pump gears are removed. Got all that for sure.

Now, on the the other side of the timing cover, by the oil pressure switch, is another snap ring, cap with o-ring and spring. BUT no relief valve under the spring.

Am I missing something? Should there be oil pressure relief valve under both spring assemblies?

 

The other side contains no components - however - crud can collect there so take it apart, clean it out and install a new o-ring.

 

OK. One confirmation that theres not two check / relief valves. But if not, why bother to put a spring in ?
I’m just thinking that the cover had been disassembled before and the piece I think might be missing, was left out.
Saying that, I had no oil pressure issues. Anyone else?

 

You don't trust me? I'm crushed.

Only one check valve. That cover is designed to support hook-up for an oil cooler which your vehicle clearly does not have. You're good.

 

No, I do not have an oil cooler.


Again, I am not sure this cover hasn't been tinkered with before, and it puzzles me why Rover would put a spring in that passage when it does nothing. That's what, .03 cents per each, wholesale at the time?


Multiply that by the number of vehicles produced.......$$$


Thanks for the quick reply, Fast. Tomorrow I'll put some juice to her, and see if she runs again.

 

The covers likely came that way (spring installed) from the mfr/supplier so I think you have it backwards. Meaning Rover would never consider removing the unused spring since that would have actually resulted in a labor cost at the factory. Much more than .03 cents a spring to remove them.

Good luck tomorrow.

Hi, I know this post is old, but by any chance do you know the size of the 0-ring. I can't find it anywhere, buy an online store in Australia (I'm in the USA).
Thanks
