Hi all
I will be starting my engine up soon, but I would like to know how I can ensure that the oil system is properly primed? I know about filling the oil filter up, but I’m insure about priming the pump.
I’m sure I have heard about removing the oil pipe from the block and pumping oil in there while the car is in gear and rocking it backwards?!?!
Please let me have your suggestions
Cheers
Kevin
Did you put vasalene in the pump when you assembled it ?
as you said fill the oil filter to brim , wait a few sec’s then again
I usually take the plugs out , & turn the engine over for a short while , 30 secs , wait , then again
until the oil warning light goes out - don’t get the starter hot if you can help it
if oil light or gauge don’t register anything after a while then …
take feed pipe banjo off , and feed the pump while pushing the car backwards in second a funnel will be needed or syringe
when done refit banjo , & try again

I did not strip the engine down, it’s just it has not been started for about 2 years and I just want to ensure that I prime every thing correctly.
Many thanks for the advice
Thanks
Kevin
well hopefully there is enough oil in the pump to prime it’s self
I think the problem with the mini is that the oil pump is quite high up in the block
most engines have the pump lower down , on the crank , or in the sump
but there are a few exceptions
Hi guys
Tonight I started to crank my engine over. As of yet I still don’t have oil pressure, how many times should it take to get oil pressure. I tried 3-4 times 10 seconds each time. I then removed the oil cooler hose from the engine and syringed oil into the block and the rocked it back in 2nd gear. But still nothing, but how many attempts should it take with turning the engine over for 30secs.
Please help
Cheers

It depends on how much the oil pump has ‘drained down’ whilst the car has been standing.
If you’ve changed the oil for a good quality 20w50 and new filter, then back-primed the pump by pouring oil down the cooler pipe whilst pushing the car backwards in 2nd gear with plugs out it should prime easily.
Connect the battery to another battery in another car with jump leads, start the engine on the other car and, with plugs still out spin it over on the starter for 30 to 40 seconds. It should get at least 40 psi oil pressure.
Fit the plugs and fire it up.
If it doesn’t it may need a new oil pump as the current one is probably worn which is why it won’t prime.

I’m using millers oil. How much oil should it take to prime the oil pump? I’m using a small syringe to inject oil into the block.
Man I need oil PRESSURE!

When back priming, especially if you have an oil cooler with flexible pipes, you could use a small funnel into the end of the cooler hose and hold the end of the hose as high as possible for maximum ‘gravity effect’. Maybe pour 100 cc to 150 cc down the pipe, but this MUST be done whilst pushing the car backwards in 1st or 2nd gear.
It usually works.
I did once have a 970 ‘S’ engine which simply would not re-prime after sitting for 6 months. We even started the engine and ran it for 10 seconds without luck. In fact we thought is was a sheared oil pump drive, but on stripping it was simply a worn pump which had probably been on maximum manufacturing tolerances when fitted. A new pump and it primed and gave 80 psi immediately.

I guess it’s a two man job then! I was trying to inject the oil and then push the car backwards!
One more question how far do you need to move the car while in gear? As I guess too much would just empty the oil pump of the oil you have injected?
Many thanks
Kevin
Happy days, I have oil pressure. About 64psi while cranking it over.
Thanks for the advice all, next step fire it up.
Cheers
Kevin
This was quite useful
Cheers

Pleased to hear you got pressure. Now fire it up and ENJOY!
