Having wired my £3 electronic Ecu It runs first attempt








My god is it loud; the neighbours came round to have a look

The down side, I can not get any oil pressure, None Zip Bugger all
Now I have stripped the engine and checked it out the release valve aswell and the only thing I can think of is. A mismatch of oil pump parts from when I reconditioned the pump.

Having oiled the cams filled the filter and run oil into the pump I still dare not run it for more than 5-6 seconds.

Any Ideas and does any one have a Good complete silvertop oil pump for sale.

Getting this sorted is all I need to get my arse in gear at get it to the rolling/running stage…………………………

No pressure? As in absolutely zero? You'ld expect to get a little even with a knacered pump?

Broken oil pressure sender???
Worth trying?

Taking the oil filler cap whilst running will soon show if you've got oil flow

Can you get too spin the oil pump with a drill on these engines ? I wouldn't know but a lot you can, if your running for such a short blast maybe your not getting there ? The whole system may need priming after a rebuild, I have never worked on the Zetec so wouldn't know ?

A man that does is sure too be along soon........

its a new sender and I have tested it it, works fine.

The pump is driven direct from the crank.
Think its going to be a fresh pump job.

Oil pump is in the crankshaft front cover as per cvh. My suggestion cost nothing to check, but might be a bit messy. Whip the cam cover of, fit plug leads and turn it over to fire, if you've got oil up top then go out and buy a new oil pressure sender switch.

The dumb question (based on experience!!!)

you have fitted the oil pick up pipe in the sump? & its not blocked etc....

I dont know if you have to modify the sump for a zetec (pinto man myself) if so, there should be a bit of a gap '10,00mm to 1/2 inch' mixing units for the old boys.

i bet you still have a smile on your face though dont you lol

sure it wont be anything to bad

Not moving any oil.

The sump and pick up pipe is a Scholar engines item. I must admit I havnt checked the pick up clearance I just cleaned it and fitted it.

I would take the sump back off and check the pickup pipe does not have any holes in the weld.

Also ensure you fitted it with a new gasket.

It is hard to believe that even a knackered pump would give zero pressure with cold oil. I would guess either a stuck relief valve or sucking air. Unless you have forgotten to refit the oil jets

Can you cut the bottom off a 5ltr can fill with oil and hold under your pickup pipe. Get someone to start the engine and see if the oil disappears quickly. If not, you may well hear/see if it is sucking air. If the oil disappears you may well find which route it takes back all over you. This will be the cause of your problem

Did you fill it with oil?

Still, at least you know it runs. There wont be much wrong. Think about it logically (draw out a decision tree if it helps)

Oil in system?
If yes - pick-up pipe attached, sealing?
If yes - pump being driven?
If yes - pump clearances ok?
If yes - pressure relief valve ok?
If yes - sender ok?
If yes - oil ways clear?
If yes - all bearings fitted and clearances ok?
If yes - damned if I know

Seriously, its a pretty simple system, not much to go wrong really.

My Zetec primed itself within a few seconds on the starter with no plugs fitted,and showed 50psi on the gauge I had primed the filter and pump but some weeks beforehand.
It might be worth trying again just on the starter with no plugs fitted , but it does sound as if there may be a problem with the pick up pipe either blocked or sucking in air at a joint.

Once had a problem with a reconditioned VW engine getting oil pressure . When I phoned the engine company they suggested removing the oil filter and spark plugs then cranking it over until oil comes out . Cranked for about ten seconds and got oil pressure. May be worth a try after checking items already suggested ?

When ever I re-build an engine or have not run it for a few months, I whip the plugs put and won't start it until I get oil prssure up, as it can damage the bearings. As said, even a knackered pump should give some pressure, even if only a few psi. Try turning it over for a while, I've had engines take a minute or more to get full pressure up.

i don't know the zetec so this could be irrelevent,

but did you fill the oil filter with oil before you fitted it?

Did you prime the oil pump?

If you do have to take it to bits I know some engine builders pack their pumps with Vaseline so they self-prime of first start-up.
Let me know if you need a third hand and I'll see if I can pop over for an evening if you want?

My zetec didn't self prime on starting after a strip down. I made a half cup from a baked bean tin and stuck it over the oil filter mount with duck tape. Plugs out, filled the can with oil and wound the engine backwards to reverse prime the oil pump. Used about 100ml. Then refitted the filter and plugs. Ureka.
Crudely drawn below but you get the idea?

Did you get this sorted in the end?

you could try poriming the rover v8 way - pack crevices with vaseleone - ooops I am referring to the oil pump. you can buy tubs in poundland, dunno ham much

do not use grease - it has to be vas. as it will dissolve in oil.

then remove spark plugs nad tun over on starter for 10-20 sec.

is there really no oil in the pump? check the pick up for sure.

can you put a tube onto the pick up - guess there will be a strainer on the end - and fill wih oil that way? maybe ru nover the engine? you will see if oil is being sucked up or not.
