has my oil pump failed?

Ok thanks, where is the relief valve and is it easy to remove and clean?

It's on the oil pump, this picture is off the SBD site, they say to replace with a nylon version:

Nylon ones arnt cheap!

Remove yours, give it and and a polish. Refit, while you're check your sender connections.

If all plugged in ok, restart engine and hope it was just the sender.

I'd put it's best to clean it in my earlier post Benn.

Has anyone actually noticed the benefit of having a nylon one though?

[Benn]

Yes can and polish, as you need to check for scoring....

Nylon is only better as it wont stick...

[marc69]

Thanks for the picture etc, it looks as though this is on the outside of the engine block so is easy to access and clean?

Am I correct in saying saying it is at the back near the oil pressure gauge?

Nylon can and will stick, I've tried both and on the advice of my engine builder I've gone back to the standard relief valve, from MY own personal experience there is no benefit of running the nylon one, get the original one on a lathe and polish it right up, make sure everythings clean and it should be fine.

ps its on the front of the pump (towards your bumper)

When you remove the big retaining bolt, the relief valve should fall out or slide out really easily if not, it needs a good polish and clean

Thanks, I'll give this a go at the weekend. Hopefully (fingers ccrossed) That is all it is.

I removed and cleaned the relief valve tonight but I switched the engine on for a few seconds and still no oil pressure.....and there was no oil that came out with it.
