I bought an escort rs turbo 90 spec about 18 months ago finally got it on the road after some fresh paint head gaket, recon turbo t3, but i have problem with the boost the boost comes in nice about 3000 but then 4000 seems to stop pulling it sound like there a air leak but could be the turbo spinning up iv had all the hoses of and checked for splits checked the intercooler all ok the top intake hose from the intercooler is really soft could it be collapsing? i havnt bought a new actuator yet. if your gental with the throttle it goes really well but if your floor it it seems to die like somethings stopping it. I cant get my head around it and living in tenerife there are no rs turbos here let alone tuning places there aint evan a rolling road lol any help would be much appreciated Thanks. Oh if you boot it as well you get a bit of a oil burning smell in the car or like a crankcase smell havnt changed the piston rings but it doesnt smoke well dont think it does only had it on the road a week its all new to me thanks again for any help.

"brand new" -31 actuator would be my first try, it could be the hoses but to be honest that problem sounds like a weak actuator

are you running a uprated breather kit? vented to atmosphere? if so this could be your smell, running it away from the kabin with a small breather filter on the pipe helps

BUT as you say that its had a recon turbo, did it smoke on boost before as it could have oil in the system still thats still burning off, or could be leaking oil on the turbo or exhaust which needs sorting

keep us updated

check the inlet manifold gasket ive had this very common theres 2 totally different gaskets on each side of the sandwich plate however some place list the gasket for both sides causing the wrong one to be fitted on 1 side ive had this on an rs turbo and an xr3i in the past by 2 separate garages (before I was clued up enough do do my own headgaskets) good luck

I borrowed a boost gauge off me mate today and it boost at 0.7 then dies off to 0.5 , 0.4 i had a look at the actuator took the clip off and it does seem a bit week i can push it in quite easy. So thats what ill get next. everything is standard on the car at the moment so still not sure what the smell is theres no leaks on turbo or exhaust the back box is blowing slightly maybe the fumes are coming in from the boot or if the rings are worn would that cause the smell ? i dont see no smoke on boost but ill get someone to follow me and see thanks for your help ill order an actuator next.

charlie boy77

ill double check them gasket but sure there ok you got me thinking now did i put them the right way lol

if the rings were gone it would smoke, have less compression and burn oil, doubt thats your problem, exhaust fumes could be your problem

actuator has had it make, its not holding bugger all boost hence losing power

charlie boy77

Ah ok cheers mate makes sense ye me mate was following me tonight no smoke so thats good. Had a few problems with it over heating first couple of days replaced the expansion bottle and removed the thermostat. it can still get a bit hot if you have been booting it but once you drive it slow for 10 mins its ok a decent uprated fan want be a bad idea the temp over here now is 30 degrees and its 12.00 at night lookig forward to the cooler evenings. One other thing im using 10 40 oil as auto data said its ok in a hot climate but today when it got a bit hot the oil light was flickering on idle drove perfect went off when you drove it and when it cooled down oil level is perfect do you think the oil was so thin cause it was hot maybe a different grade oil?

i would test the oil pressure! what oil pump is fitted?

with over heating is the fan ingaging on its own?, go onto motorsport developments and order their uprated fan switch and low temp thermostat and they should help the fan to come on at a lower temp

contact opie oils on here he will be the best to advise you with the oil problem, but do not drive it while its putting the oil light on, it could ruin the engine, as said borrow a oil pressure tester and see what pressure it has when hot and if its ok then its oil but a friend had the same problem with 2 oil pumps, both burton high pressure ones and after fitting a genuine ford one it cured it

charlie boy77

The fan comes on on its own no problem but never really stops in the day. i was thinking the fan cant keep up with the heat over here it has been hot here lately. Do you think its better to have a thermostat in evan here in Tenerife. Maybe if i go to scrap yard and find a decent fan off a citroen berlingo diesel or something that might help the cooling it doesnt over heat it seems like its just running a bit hot like in the traffic i put it down the the heat we been having and i think the radiator fan is crap my self. I havnt changed the oil pump and not sure whats on it so thats on my to do list as well now ill pressure test the oil and let you know cheers

i think a good 12" spal fan would be ideal if you have a standard intercooler, and i would reccomend running a thermostat but a decent low temp one with a uprated fan switch too suit.

the boost drop off could also be caused by the heat too, if the car is in 30 degree heat i dread to think what the charge temps are with the standard intercooler

matty325

you can get special coolant that doesn't boil till 180c uses 0 water seen it in rtro cars mag the other day think that would be good,its designed for older style car s as well

Hi just a little update the whether has cooled down and uprated the fan switch Its running alot cooler . Been doing loads of reading and like the sound of the grs intercooler evo 3, after i get the new actuator some other bits.The only problem is i dont want to start cutting the bumper and stuff do you think that enough air would go through with out cutting. I was thinking two 9 inch kenlowe fans for the traffic and to take in account the warmer whether or do you think one 12 inch will be ok.


cheers charlie.

matty325

I found on my zvh rs turbo that my twin fans and front mounted intercooler restricted my radiator and made the car run hotter. in the end I had to cut my bumper open but it was an 80 spec bumper don't know if the 90 spec ones flow more air or not,hope this helps

As you probably read the RS Turbo's ran warm a lot. I think it will be usefull for you to change your oil. A lot of people ran thicker oils already without problems. As you are running in an envoirment that is about 15 degrees warmer then ours you will be fine with it too and running better oil pressure.

For the boostleak the idea is that you put your complete system under pressure. For example block your exhaust after turbo and for example on the place of the meteringunit and put everything up to boost level (0.7 bar) and you will find all the leaks you have.

The dropping off boost might also be higher inlet temperatures. Everything heats up and with the higher inlet temperature ignition will start to retard. Causing you to lose boost.

You can always try the wastegate first as its easy to do. Make sure that you have the boost gauge of your friend with installing the new wastegate as you have to monitor the pressure.

If the above is not working it would suggest to buy a wideband lambda sensor and install it. Boost drop might be cause due to wrong fuelling. You have to know this else your engine might be scap soon! You can do a pre check to see if your plugs are white, then you are running lean!

charlie boy77

Thanks for you help i wouldnt mind cutting the front bumper but that would be a bit over the top for the police over here lol there a bit funny with things like that. im gonna try and redirect the air filter to where the washer bottle is to help get a bit more cold air in you can imagine the air intake temp under the bonnet. Im gonna look for an intercooler that's long and narrow so it can sit behind the bumper at the bottom hopefully not restricting to much air to the rad with a decent fan hopefully should keep cool enough. I bought a cooler fan switch it still gets a bit hot when your climbing a long hill but dosnt over heat.cheers for your help mate.

Hi mate i checked my plugs and they are yellowish what color should they be. I changed my oil gonna keep up the oil changes every 3000 kmh .
Im gonna try and relocate my air filter to wear the washer bottle is get some nice cold air from there you can imagine the temp under the bonnet. do you know the standerd setting for the mixture screw on the air box i havnt touched it but maybe someone else before me did is there a standed position. When i get my new waistgate im gonna book a trip to gran canaria for a session on the rolling road ill let you know how it goes cheers for your help

Hi guys dont know if any one has come across this before last couple of days the cars been running really rich it starts up but miss fires with black smoke coming out and stinking of petrol if your gentle with the throttle it eventually it clears its self. this happened a couple of weeks ago but was ok up until now i read up about the k jettronc unit can go bad i ordered some plugs from ford today which will be here tomorrow couldnt find them any where else. Any ideas i know the best thing to do would take it to a specialist but the nearest one is gran canaria i think cheers for any help

There is no standard setting for the mixture screw different on every car and you can't really see the position without opening up.

First of all it sounds like you have massive overfuelling. Take your oil off the car see if its stil normal and not full of fuel. If ok just refill. So use sg clean to catch the oil

Do you still have your old start injector connected? Else i suggest taking it off. This one might leak or be opend by false info of coolant temp sensor or sg

Still overfueling? Take airfilter off and have a look on the valve in a clean enviorment with just standing and hitting some throttle. Does the KE tronic valve move ok or is it stuck?

Still overfuelling? Buy a wb lambda sensor and Instal it after turbo in the exh. Take about lambda 0.8 in boost and 1 in cruze. Then take it to ur tuner for decent set up

Watch out for bore wash. The large amount of fuel injected takes the oil of the cylinder causing massive wear. This will be the case if there is fuel in ur oil

So be careful!

charlie boy77

Hi mate the valve seems to be ok but is there any way of cleaning it. i changed a coolant temp switch today the one that goes in the t piece of the water pipe i couldnt find the yellow one any where evan ford says no il get one on the internet its still rich but changed the oil the other day. i redirected the air filter today i mounted it in side the wing where the washer bottle is just have to find a place for the bottle now. i used an orion air filter pipe which goes perfect through the hole should get some nice cold air in there aint tried it properly yet as trying not to drive it untill i get this over fueling sorted.Thanks for your help!!

Old ford

Get an Airtec radiator and inter cooler set comes with twin fans that fit between the inter cooler and rad, just fitted one on my s2 and no need to cut the bumper.
Twin fans push out loads of cool air.

charlie boy77

Sweet mate thanks for that. Hows the inter cooler is it a big difference?

1.9 xr2 on 40's

Before messing about squeeze the middle boost hose from meter head to the turbo because if it is weak and squashes easily its collapsing when the turbo is sucking and thats your problem
Its an older issue thsts gone since people fitted samco hoses but it used to be so common you could buy a spring to stuff in it to keep it blown out
Don't spend any money or tamper with anything until you know

Red_bull

I think all of them are feeling weak. If it collapses he can't run 0.5 boost is it?

1.9 xr2 on 40's

Even on std boost it will suck in and cut off the air leaving the fuel that went in not burnt and black smoke out the exhaust
I've seen lots of bodges to stop it like wrapping in tape or cutting the hose in half and putting in a piece of pipe
A samco middle hose will work a treat

Old ford

Wouldn't say it makes a big difference on its own but with the alloy rad and twin fans it does, did a track day after just fitting it and car went flat out all day then drove it home 2 hrs and no overheating probs temp gauge hardly moved.

charlie boy77

Just came back from a drive read your message and went out to feel the hose and it is soft. it boosts to 0.7 then dies of strait away to 0.5 but it holds it better down hill or is it just because im going down hill lol.
Any one had a problem with over heating up hills i dont mean a 500 meter hill i mean a 5 mile hill or a gradual hill climb im not driving hard not above 3000 and it slowly but surely goes into the red if i let it soon as i turn around come 5 mins down the hill it goes to half another ten mins its at quarter i can run for 50 miles at 70 mph on the motorway and its perfect dont loos no water. i changed head gasket, water pump, it anit got a thermostat. If i remember right my mates opel frontera over heated up hill i we changed the rad and it was perfect any ideas
Thanks Charlie

charlie boy77

Hi mate i got new silicon hoses and -31 actuator its running so much better 1 st gear is perfect 2 gears perfect (i think ) but third forth and fifth the boost gauge dies off slowly is that normal should it hold boost all the way through the rev range my fuel pump is noisy gonna get one sorted soon could it be low fuel pressure . I do need to go and get it set up on rollers but the nearest one from me is gran canaria so gonna get booked up for feb need a radiator first as well gonna going for the alloy one any idea's on the boost dying cheers mate.

Sorry to hijack the post but is this a White S2 in Tenerife....??

If so i met you in september whilst on holiday outside Taboo's....

Cheers

My best friend why don't you install a wideband lambda sensor. You are just guessing what your engine is doing. Measuring = knowing!

It's normal that a turbo drops off a bit on boost

charlie boy77

Hello mate yes your right that the white RS How are you mate

TIL13R

Very good thanks mate.... How is the car coming along....??

We are good here and all 3 of our cars are taxed and Mot'd for the show season this year....!

drsrst2zvh

Where about sin tenerife do you live mate? I used to live in Los Olivos, Adeje. Used to be a white S2 parked up the hill down a side street near the town hall wasn't yours was it? My dad is always over there every otehr month so if you ever need anything taking over let me know.
