Sorry me again

I believe that I didn't prime the oil pump before fitng my own fault but before removing parts from the engine a quick question

If the pump wasn't primed would turning the engine over on the starter suck oil up to the pump or by not priming it am I going to have to remove the sump?

I know I'm going to have to remove rocker cover etc but I thought the more I found out before wading in the less bits I may have to remove as i didn't half have fun keeping gaskets in place whilst tring to fit covers sumps etc.

If anyone would be kind enough to let me know whether the pump would suck up oil without being primed I'd be grateful.

last post on subject I promise

Pinto's are usually self priming.

think about changing the oil and filter. All the oil is removed and by filling it from the top sends it to where it needs to be. Crank it over a few times with out the plugs in if it's been stood for a while but you should be fine.

If you want to pump oil round a pinto without turning over the engine, remove the dizzy and peer down the hole. That 'hex' drive you see down there drives the oil pump. Fix up your drill with a suitable socket well stuck on an extension bar (1/4 drive kit is good) and rotate clockwise looking down on it till oil squirts out of the cam spray bar. And yes they usually happily selfprime. (If the pump is worn and absolutely dry as a bone a little oil trickled back into the pump through the outer hole in the filter base plate on the block will fill the gaps and get it primed.) Oil system primed without any pain to the bearings. Refit dizzy.

Many thanks fellas for taking the time to go through things with me. i know i've posted several questions which could be taken as the same question but I just wanted to be sure of the facts before diving in and either making a hash of it or completely ruining my engine which I haven't heard runnng yet.

One very last small question. Any tips and tricks on how to remove the dizzy so i can put it back in later with the rotor arm being as close as possible to it position when I removed it?
I know i could mark the block and dizzy but wont the rotor arm rotate when reinserting because of the gearing on the botton meshing with the aux shaft?

Again many thanks it's a big learning curve this car building thing

There is already a TDC mark on the dizzy case to set the rotor arm. if you mark it up before you take it off you should be able to put it back the way it belongs. usually the rotor moves about 20 degrees anti clockwise as you drop the dizzy back in. A bit of wiggle is all it takes!

Many thanks

I see from an earlier post that a 1/4" socket and extension should fit down onto the shaft for the pump

Being a bit inexpereinced, is it okay to just clamp the extension straight into the drill chuck, will it be damaged and does it need to be done up tight i.e with a chuck key or just a nip by hand? if this isn't okay how do you secure the extension in the drill

very last question now, anyone know the size of the pump shaft?

many thanks for your time and patience answering my questions. it's very much appreciated

Hi There,

As far as I can remember I didnt have to prime the oil pump, a few second cranking with the plugs out did the trick.

If I were you I would remove any senders and adaptors frm the block and go back to the standard pressure switch directly into the block, rig up a test lamp and see if the light goes out.

This will rule out any after market senders /gauges etc and give you are starting point. If you cant get the lamp to go out after a few attempts then its time to start further investgations.

John.

to answer question - depends o nthe engine. the rover v8 needs to be filled with vaseline, many other engines e.g. corss flow and it seems pinot are self priming.

If you are going to whizz the oil pump with a drill, do it with a cordless at the lower speed -once the pump is primed, it will give a kick that could wrench the drill from you hands resulting in injury.

thanks for the safety tip, I must admit not considering that. I though without it being connected up to anything else it would of spun without much resistance.

both my wrists thank you
