My escort cosworth has a wee problem....

when coming onto full boost and giving it a bit my engine is stalling, no matter what gear...full boost = stall...then after about 2/3/4 seconds it will bump start....

help...

 

blocked fuel filter ? Knackered fuel pump ?

 

trapped wire?? crank pick up?

 

u can hear the fuel pump whining a bit, which sounds normal cos my last rs turbo had that aswell....how do u check the fuel filter...

 

bttt

 

overboost ???

 

you don't generally check it, just buy a new one and see if it cures the problem.

 

I think the boost has been turned down a tiny bit from standard as an old man had it before me.

 

Its overboosting mate either turn the boost down a tad or get it chipped and run even more !!!!!!!

 

std boost is about 8 psi from memory

so whats it running atm ?

 

im not 100% sure tho....the overboost hits the first dash, then full boost settles half way round the solid bar on the standard boost gauge.

 

get a real gauge on it m8 to check it out

 

That sounds like the prob then mate,its prob just on the limit,try half a turn anticlockwise on the actuator............should do the trick

 

i think the gauge is working fine....so its an overboost problem do you think?how do you sort that one out?

 

the gauge don't give u a psi reading tho so really u have no idea what boost your running

adjust the actuator

 

Is the car std or chipped? Don't forget Escort Cossies will 'overboost' as std(shouldn't cut out though) as it was designed to under certain conditions.

 

the car is totally standard...

 

Got a similar prob. on my saph. can I ask a real :blonde: question.
Which bit is the actuator?

 

i know what bit it is but i dunno how to turn it down lol/....

 

The actuator is the (usually) bronze/silver coloured thingymabob attached to the turbo compressor housing, with a rod that goes to the exhaust wastegate. Don't recommend playing with it though if you have to ask what it is

 

if i leave it into the ford rs garage near me it will cost an arm and a leg to fix.

 

i think i might see a problem,ill try and take a pic now.

 

Skiman, it might not be overboost cut, are there no reputable tuners near you who could diagnose?

To adjust the actuator you really need to remove the heatshield, and then ideally you need to unclip the actuators arm from the wastgate (otherwise you could possibly damage the diaphragm in the caspule if you just slacken the nut, and twist the rod), then adjust, refit, test etc. but again, you really want to be doing this with an accurate psi boost gauge. As you can imagine, it gets real hot in there if you need to re-adjust!

Skiman - check all the small bore boost pipes are still attached......

 

anyone on msn that can help me? ive a pic to show u and photobucket is offline.

 

email it to me at bill@..............com, and I'll post it up.

Good point - Well made!

 

email sent.thanks

 

The pic :-

Shows that the coolant hose where it attaches to the turbo,it seems to be leaking due to a very tight jubilee clip which has cut into the hose, would this affect it?

 

Amal valve may have blown apart of the pipes split... relatively common.

 

so get a new pipe? would this cause the engine to stall on full boost?

 

Was just about to say that's not a boost pipe! Ah, you have a small turbo EsCos too .

 

cheers for hosting that dude...u can see the circular bit of the pipe should not be there and if i move the pipe at all,coolant leaks onto the turbo....could this be the problem?

ahh yes a small turbo...

 

Are you CERTAIN its not chipped?

Have you actually LOOKED?

 

i havnt looked...but i was sold the car by one of the heads of the rs owners club n.ire and he said its not chipped...it doesnt seem that quick to be chipped...

 

just been out, started the car and checked this wee pipe and its definatly leaking coolant onto the turbo...could this be the cause of the stalling?

 

maybe ragging it against a rs turbo could be the problem?

 

If you've no valid input to this big hole dont reply

 

No i doubt it mate, but i would get it sorted coz it's not good to have water dripping onto the turbo!

Try to strip the pipe back hopefully it will be long enough to be able to cut a bit off

you might want to check that the turbo hasnt failed,if there is too much play in the shaft this could cause the compressor to stall hence restricted airflow,maybe cause it to stall

you'd be a brave man taking an RS to a Ford garage
