i have just had a reconditioned turbo (t3) put on my st escos because it was smoking before... but it is still smoking, only when i leave it run in gear, no throttle, and mainly when i go down hills. it doesnt smoke when i drive car normaly, or accelerate, just when i leave it run in gear when i shut off, could it be there is oil in my intercooler from before? or could it be a blocked breather because it tends to happen when im doing down hill first.

there is a breather pipe going into my k+n airfilter... is there another pipe going into the inlet manifold...(cant think off top of my head).

any help be great guys

cheers liam

 

Sounds like an engine problem to me.

 

my mate had a quick look at it today, and the breather pipe which is feeding back into my air filter is sucking rather than blowing warm air, so its going into his garage tomorrow, so hopefully its a breather problem :/

 

nope your problem is your car CANNOT RUN A T3! this is a basic mistake people think you can just swap the turbos you cant!

what you have done it your either gonna shaft the turbo or the engine by running a turbo that the car isnt mapped for!

one lad i know even tried having the car setup with a t3 on and it NEVER ran right,,, only way back is to get a T28 back on...

 

it was smoking with the t28 on, and because when i bought it, the guy had the engine rebuilt with low comp pistons, the t28 seemd to run out of steam, where as the t3 pulls much better, it had a ggr305 chip..etc., so it was smoking before...and still now, should the breather be sucking? when i put my thumb over it its like a vacume there, i want to sell the car soon and just wanna get it right before i do, it doesnt smoke all the time, just on the over run at high rev and then when i power back on....

can you get a breather kit for an st escos?

 

is there oil in the boost pipes.

 

the t28 ran out of steam as its not a high power turbo! not trying to insult here but seriously chap you cant go slapping any old turbo on! just cuz its got a chip on! thas like me saying i know i used to run a t34 im slaping my GT35 on it'll be fine it wont!

I'd say if im honest you HAVE either shagged the turbo or the engine....

 

i asked the question a couple of months ago about fitting a t3 on a st escos, one or 2 people said they had done it with no complaints, and there was no negative feedback, so i went ahead with it, this oil burning on the overrun problem has been there a while, i kno you cant just slam anysize turbo on, but i thought the t3 would be ok as i had the idea from other people who had done it?

also i just went out in the car and this burning only occurs when im overunning down hill then power back on , it doesnt do it at all on the flat, it must be a breather problem or something to do with when the oil is more to the front of the engine when going down hill,

and there is no oil in the boost pipes and the turbo had done about 50miles since re-con..

????

 

if it was burning when im powering on normal, or when changing gear and giving it some id say ok engine, rings or what ever, but its not...

just when overunning in gear down hills?

 

dont worry mate its not the turbo and iv fitted loads of t3s to st escos with no probs..
The problem you have is it needs a proper rebuild probably just new rings but it sounds like its deffo the bottom end...

Whats the car like and are you willing to sell at a good price needing the rebuild???


cheers danny

 

put a t28 back on or change to a l6, l8,p8 ecu .

ive bought a st escort with t3 and im unsure what to do

 

people can say this or that, it WILL NOT run right(or damage the engine) on a T3 without a custom map which i believe noone offers bar msd who had problems with this still....

just sticking a chip in and shoving a t3 on will NEVER be he same as a T28,, thats like saying apple pie and custard is the same as apple pie with icecream! there 2 different ingredients!

 

hi danny well if it wasnt smoking i would be putting the car up for 15k, the engine was only rebuilt 20k ago by harvey gibbs with new pistons, re-shelled and mild port and polished head, i wouldnt take anyless than 13k as it is now, i have one or 2 other little faults with it which were to be sorted before i sold, if you were interested give me a ring 07884950524 liam

 

u looking for es cos?

 

yes the breather will blow out warm air.
assuming its not blocked up, ETC

has your exhaust got a middle box in it??

The turbo might still be the problem.
if not then it will be either valve stems,........or piston rings

 

no the exhaust just has the back box's, the breather isn't blowing warm air, its a suction., my mate took the breather off yesterday and said its not blocked, can i just fit like a straight pipe off? it seems to be plumbed in to a couple of other places tho and what looks like a solenoid?

 

if it was piston ring wouldn't it be smoking all the time when im boosting and stuff?

 

you wont always see it smoking when your on the move!

 

just like to say quite a project you have done with yours, i havnt got the head for that anymore and im only 24, im gonna have to try the breather system first before i go looking at engine as its the least costing... dont know anyone with a breather system to sell???

 

Yes mate not updated mine for a while now cant be bohered updating it now really but car is @ MAD having the 500+ hp engine done be back in the next few months thats thats it done no more! Then as you say i've had enough with tinkering now hahaha....

do hope you sort it as said not meaning to be funny but just going on what i know and been told by people,,, GOOD LUCK!

PS plenty of second hand kits prob on ebay go have a mooch!

 

I also have an ST with GGR 305 and a similar smoking problem turned out to be a trapped breather pipe!

 

i took the cossie out again today, gave a good scumming, shut off at high rev, let it run in gear, powered back on...no smoke, as soon as i went down a hill, shut off, let it run in gear and power back on it smokes, but definitely doesn't do it on the flat...???

 

could it be that when the oil is at the front of the engine...e.g(when going down hill) that the oil in the turbo's oil return pipe comes up against the oil in the sump it cause's backpressure forcing oil through the turbo seals?

 

Mate, try another turbo on it, even though its reconditioned, borrow one of someone who's car is not smoking and eliminate that first, i had the same problem, recon turbo, still smoked, checked all breathers, still smoked, did all the valve seals, still smoked, did the bottom end and rings, still smoked, checked exhaust for oil in it in case exhaust heated up and started burning of the oil that had been blown out through the turbo, finished up putting another turbo on and it did'nt smoke, got it reconditioned again and no smoke, took about 4months for all this hassle to get sorted, did my head in lol

 

yeah i have a breather kit coming this week im gonna try that...they try another turbo..
