is your alternator an rs1800 one that fits the cvh mount?

cheers andy

its a mk3 fiesta zetec alternator - non power steering & non air conditioning

[filtra]

Vacuum leak possibly, check your master cylinder for air leaks or other parts of the system that rely on vac.

No, a vacuum leak would increase rev's

I appreciate they are completely different systems but on my pinto sierra, there was an air leak on the master cylinder causing the engine to idle very low and conk out comming to junctions/using brakes at low rpms.

Just a thought.

i think i have got to the bottom of my overfueling

I think the fuel pressure is a tad too high. The combustion chambers some how are getting fuel in them when i leave the car standing. Which seems to me like worn out injectors or seals. Upon startup the fuel smell is quite strong from the exhaust.

Another thing which may be causing problems is the sierra rs cosworth external fuel pump. It may be a bit overkill for the zetec setup i have.
im going to borrow the fuel pressure guage from work tomoro and take some readings at idle and when reving the engine from cold. Then check it again when warm.

It doesn't matter what pump you have as the reg will send the excess back to tank. If the injectors were so bad that they leaked fuel into the chambers then I doubt it would run as well as you and Simon said.

Have you got another pressure reg you can try?

[knuckles]

Have you got another pressure reg you can try?

no i dont.

i was considering obtaining a complete inlet manifold from a si or something to try to see if my problem is that.

Sounds good, you can change the reg with two 8mm (I think) bolts, and it pulls out. Would be quicker than changing the lot...

Have you replaced the VSS? This was the route cause of over fueling and crap idle on my zetec mk2 the forst time around. When i done the conversion I did not bother to run this sensor and as a result I had to screw a small nut on the threaded end between the TB and the throttle linkage, this was the only way it would idle with out knoking out, I had no idea of the importance of the missing sensor. When I reinstalled the engine complete with new loom i ran it with the VSS, no more s**t idle and ran a lot sweeter too.

i do run a vss on the ib5 gearbox. But i havent tried another one yet.

i have checked fuel pressure today. Will upload a video and results shortly

[knuckles]

Fuel pressure guage reading when ignition turned on




Fuel pressure reading when engine running at idle.
this goes up to 2.7 when engine is accelerating.

Ive been told this is normal readings and that the pump is working normally.
Which leads me to think it could be injector related issues, ecu or even wiring loom fault



here is a short 41 second video clip of the lumpy cold running im experiencing

[Excursion]

What oil do you have in it mate?

[Tweek]

Different sound I've noticed is your timing belt could be a bit too tight or a pulley's got dodgy with that whine?

Aux belt is a bit loose or dry.

[knuckles]

5w 30 ford formula F

the timing belt was checked when building up. simon also said the belt sounded very tight. But it was same noise on the previous engine.

Yes aux belt is slipping a tad when cold. Its a brand new alternator and new motorcraft belt.

rough up the pulley to the alternator if thats where its slipping

[knuckles]

one thing i have noticed !

it is very hard to start from cold , i get alot of missfiring for a few seconds upon first start up
i think the injectors are allowing fuel through to the combustion chamber which is building up.

i may have to remove the injectors to confirm this by doing a drip test but i cant think of any other reason for this massive over fueling issue

[knuckles]

after the trip to isle of wight in the mk2 i drove back saturday evening. When i reached within 7 miles of home the car began to misfire really badly. All the power has gone completly.

I have tried new spark plugs, new leads, 2nd hand coil pack, swapping injectors for others. Ive Checked the timing and that is spot on ...
Ive done a compression test this evening and results are as follows.

Cylinder 1 - 125 psi
cylinder 2 - 25 psi
cylinder 3 - 25 psi
cylinder 4 - 125 psi

To say im pissed off would be an understatement. This is the 2nd engine ive obtained and has gone pete tong. I refuse to locate a 3rd and go through the whole process again.

[jayrs]

as said on the phone mate, do the other tests i said, then get the head off to see whats going on

[jonyb4]

man thats bad luck

you think its the rings?

and to go in two cylinders!

[~nomad~]

s**t awful luck man. Stick it in the garage and revisit it when you are less pissed off (as I am sure you are fuming right now)

[knuckles]

ive been told on a few ocasions by various people that zetec engines are meant to be more reliable than the older cvh engines.

ive had nothing but grief since converting over to 16v.

[Excursion]

Ahh man, not again. The Zetec is a much better engine, but like any engine, if it's not been serviced well and looked after it'll give problems. The Zetec's are old now and the cars they come from are near scrap value, so it's hard to find a Silver Top that has been looked after with regular servicing.

You may get on better with a Black Top from a later Focus, if you can be bothered to convert? If not do what Jay advised and look to rebuild it in the long run.

[Excursion]

Get this: http://www.ebay.co.uk/itm/Ford-Zetec-Si ... 3815373419

By the grime, staining on the block head and condition of bolts I would say that mileage is genuine. It's on Ford leads so it's been looked after even if the mileage is slightly out. It's also a series 2.

It may work out cheaper than trying to fix yours?

[jayrs]

i wouldnt advise buying a engine you cant hear running again

[jonyb4]

would be even better if you could drive it

[SEG1]

sorry to hear clark.

could it not just be the headgasket?

[Ratspeed]

sorry to hear clark.

could it not just be the headgasket?

Thats what i was thinking, gone between the 2 cylinders

[knuckles]

sorry to hear clark.

its maybe just a head gasket but for it to lose that much psi on both cylinders at same time its very unlikely.
to do a head gasket on the mk2 is a engine out job. You cant get the timing covers off to get at the tensionier. You can just about get a spanner on the bottom pulley.

I put money on it being the head or valves being broken

[Ratspeed]

With number 2 and 3 both being 25psi id opt for the gasket blowing between the 2 mate.

Either way it looks like the engines coming out and the head off

[jayrs]

as i said on the phone clark, do the tests, then get the head off, check it over and have a loom at the gasket.

[rs-tom]

im sure u can get the head off while in the bay i changed cambelt with engine in on my xr2

[jonyb4]

if the gaskets gone between the cylinders you'd likely get loads of extra pressure in either the oil system, or the coolant system,so thats one way to tell

[knuckles]

mk2 will be put in a garage over winter. i wont take out the engine till new year now. Im still not decided what route to go down regarding engine.

i wont be stung a 3rd time with this car. No more 2nd hand engines.

i will either rebuild the 2.0 silvertop from top to bottom , new pistons rebore the lot or may even go back to the good old cvh turbo.
If i stick to zetec i will end up needing aftermarket managment , ecu. The ford stuff clearly hasnt done me no favours considering the faults ive had with 2 engines and this overfueling.

its Such a shame. It seems every time i get one problem fixed 3 more crop up.

[Ratspeed]

Not if its just gone between the combustion chambers. It will only pressurise the cooling system if its gone between the chamber and the water jacet.

[knuckles]

Still havent stripped the head off this but it now has a home over winter in the garage.

i have decided come the new year i will begin the process to build a slivertop zetec turbo engine
The hardest part will be fitting in the T3 turbo and intercooler without chopping up the front of the car.
I still want it to remain a sleeper
