My mate has just fitted a 2wd cossie lump to his A reg XR4i.

I know, i know why you may ask? But its his baby and he's done it all himself and is a proud bugger.

Now the problem is after starting it today and adjusting the dizzy so it ticked over ok, he let it run for a bit but he's not getting any oil pressure??

He's checked the oil level and its upto the max mark on the dipstick.

Any thoughts?

Missing oil pump drive bar under the dizzi !!!!

By the by, adjusting the dizzi does NOT adjust ignition timing !!!!!!

The sensor is used as a phase or cyclinder identifier only !

Cheers, what i'm going to do is note down all the responces i get and let him have them as he's not on the internet.

Anymore? Prob 100's

as per simon, line the dizzy up within 10degrees of the mark. it sorts itself outself out timing wise, you cant adjust it by twisting the dizzy like you do on other cars

Diddeling the dizzy is fine for the timing, but how does that help the oil pressure?

Or lack of in this case

If the bar was not their then surely the car would not run as this drives the rotor. Am I wrong??????????????
Has the oil pressure switch been checked at all.

The cam belt drives a shaft which drives the dizzi.
The dizzi has a hexagonal bar which slots in the bottom and drives the oil pump.
If this bar is missing, the engine WILL run and you will have NO oil pressure.
Also, if the engine was rebuilt and the oil pump was NOT pre-primed then it
will not pump oil either .

RST_lee, Dunno mate, all over my head i'm afraid

As for the oil pressure switch, i'm sure that'll be one of the first things he checks.

He did mention the slight poss that the oil pick up aint in the oil properly? Would this be a cause?

SECS, A good theory mate, Ta

Simon, How. Thats not being disrespectful as I said in my post i was not sure. but does that not drive Rotor?

RST_lee,

The pump is driven DIRECTLY of the shaft that is common to the dizzi.

A hexagonal bar about 3 inches long is used to transmit rotation from the bottom
of the dizzi shaft to the oil pump that sits below it in the sump.

The dizzi shaft is driven half way up by a worm gear from the auxiliary shaft
that is in turn driven off the cam belt.

So is short, the cambelt drivens the aux shaft which drives the dizzi shaft which
drives the hexagonal bar which drives the oil pump.
If the hexagonal drive bar is removed, the dizzi still turns but the oil pump is
not driven so no oil pressure but a running engine.

This ONLY applies to cossies or ford "pinto" engines !!!!

Hope that makes sense.

Would this be the one and only thing to cause no oil pressure or is there other probable causes??

for the daytime crew.........

pugo

holed or incorrectly fitted oil pick up pipe, oil pump relief failure...fooked mains or big ends, cracked oil gallery in the block

did he build the engine or did he buy it second hand and not see it run????

BillyCabrio

pugo, He bought the engine blind (didn't see it working as far as i'm aware) but did mention that for some reason the cams were in back to front But it did have a newly rebuilt short engine.

Any how, it starts on the key now and ticks over just fine - just the oil problem.

pugo

is it not as tappety as fook?????? if it is........it ain't fine

how does he know he has no oil pressure??????

Pugo

BillyCabrio

Now you mention it, the fact that it IS tappety is his theroy behind the lack of oil pressure.

He's hoping it is just the pick up.

pugo

is the oil light on??????

tell him to screw an o/pressure gauge straight in the side of the block where the sender goes and have a look as it may just be a bit dry still on the top end or it may have a head gasket gone and not getting any oil to the top

if the light goes out and the top end is tappety, it would make me wonder why the cams had been removed!!!!!!!!

Cheers tho.

for the afternoon people.

just open the oil cap when it's running. if you have oil up there and spraying about, you must be pumping oil up there. if not, stop it immediately and fix the problem. everything will be quickly fucked by running without oil.

listen to SECS, his advice is spot on. remove the dizzy and look for the hex bar. if it's in there, connect it up to a cordless drill by an extension shaft and spin it up. you should get oil pressure then (which can be checked by removing the turbo oil feed hose). if the bar is in there, but still no oil flow, it can be, as SECS says, that the oil pump was not primed before fitting and may have an air lock so doesn't suck oil up. don't know what you can do about that, short of removing the sump and priming the pump.

foreigneRS, Dont spose you know how to prime the pump do you?
