as above got my engine in and turning over on the starter, no fuel yet but put oil in and turned it over,

should pressure show on the dial, its a mechanical type not a light

Yes, it will take a few turns but it should show.

dojj

iTrader: (3)

yes, but it won't be much

well the battery is pretty flat so i will give it a charge, its a low comp turbo engine aswell if that makes a differance?

Turbo Transit

Take the plugs out when winding it over

Engine will spin faster as theres no compression and also will reduce the load on the bearings until they get oil pressure.

and make sure you've prefilled the oil filter with oil too.

Very good tip this.

done all that mate, problem is because the battery is shit i can only turn it over for about 8 seconds, mite take the battery off my van and try it

mk1turboestate

iTrader: (2)

iv left it charging and still no pressure, any ideas? or is it not turning enough?

Yes you should, the light should extinguish as well, although, of course this isn't applicable in your case.

Plugs out,try a little squirt of oil down each bore,quick turn over,plugs in and try again.
Had this exact same problem with a rebuilt rs turbo motor,tried all day and it showed no compression,I drove the car in and pulled the motor,swapped heads,my mate timed it up from a known mint bottom end and no compression,did this and she was the sweetest turbo motor I ever heard.
Never failed to start again.
It can sometimes do the plugs in and smoke a bit but it will clear and then you`ll be fine.

15 psi pressure is at my dial when i turn the engine over just on the starter when i use my transit battery, i think that this should be ok, what do you think?

vaughant

Sounds fine to me on a low comp turbo engine,but I'm sure more experts will be along shortly.
At least your getting something now?

DazC

iTrader: (1)

He's asking about oil pressure mate! Not compression!

dojj

iTrader: (3)

15 psi is fine on just the starter

i thought so, cheers everyone, sorting out the wiring to the fuel pump now, does anyone no which wire does what on a fiesta turbo loom, fuel pump live etc, its in my mk2 escort estate

Doh!!!!!

tabetha

As said 15psi is fine at starter speed.

i would of hooked it up with jump leads and left the van running. should turn a lil but faster.

mk1turboestate

iTrader: (2)

would do mate but its the wrong way in the garage so i cant

bunnymofo

ahh, o well. thats where it comes in handy to have a giant set of jump leads. i bought 40meters of 35mm2 welding cable to make jumpleads, but ended up replacing the leads on my welder, so got to look for more now. as jumpleads always seem to be that little but short :@

mk1turboestate

iTrader: (2)

i need a long pair of cables myself so i can mount the battery in the boot

bunnymofo

you only kneed one cable.

mk1turboestate

iTrader: (2)

i would rather run a decent earth to the starter, it is an old ford

Any luck yet matey.

bunnymofo

ahh, good idea, i might do that now...............

what is everyones obsession with this, just start it you will know straight away if its got oil pressure or not, i changed a sump on a e30 325i years ago and the oil pump drive shaft didnt engage properly started it up and light never went out, it ran for over 10 seconds before i realised ! took sump off redone pump drive and started it, that car was still going 2 years ago 30k miles later still spot on and a hard driven car, its very difficult for the pump to pick up and push oil right round your engine at cranking speed but it will instantly pick it up at idle if its built correctly.

normally i would do the same but iv fitted a different sump and pickup pipe to the engine and the wiring and fuel lines wernt done when i posted so i wanted a better idea

When I rebuilt my Cosworth engine I removed the turbo oil feed line and turned it over until I got oil coming out of there.

Then started it up.

mk1turboestate

iTrader: (2)

that was another reason i wanted oil pressure, the turbo hasnt been used in a couple of years and i wanted to make sure it already had oil in it

tabetha

There is something seriously wrong with a cossie if it doesn't pick up oil at cranking speed even on a brand new build, so long as the pump has been "wetted" with oil it will pick up no problem, some bad engine designs in the oil dept like certain evos often need oil pouring down the supply hole from pump to filter after long lay offs to get pressure up.
