Oil Pump

[actwon]

Hey All

I have a question. Since I am rebuilding my engine, I was wondering if the oil pump is self priming? If it is not, any suggestions on how to prime it? I know that the 4cyl's are not self-priming.

Nathan,

Don't know about the V8 but why do you think the 4 cyl oil pump is not self-priming? On the engines I have taken apart I did not have to prime the pump and I've seen no reference in the manual to a priming procedure.

Just curious....

Replaced the rotor and annulus in my oil pump last year and packed the pump full of grease to prime it (think you can use vaseline as well).Sounds a bit crude putting grease into your oil but I think it's a recognised method.

Steve from SJ sportscars reckoned it would need to be primed, think it is common to quite a few cars/oil pumps.

Disconnected the turbo feed pipe and turned the engine on the starter with the spark plugs disconnected till the oil started to come through , took about 40 secs. (and a bit of worrying) before any oil came through.

Used the oil for about 200 miles then changed it.

Then you're lucky! My buddy and I just finished rebuilding a Carb'd turbo Esprit and we used a pressure pump to pump oil through all ofthe galley's before we started the car. While I was gone my buddy and another associate cranked the car up and went for a test drive, well, his associate never looked at the oil pressure and ruined a con rod bearing. That's why I was asking about the priming procedure and if the v8's needed to be primed.

Nigel,

Thanks for the info. I hope to be starting the motor in about 2 weeks.
