hi can anyone help me because i have no more hair to pull out, got a 2wd saff which seems to have an overfueling problem
when the car is stationary and you rev it up to about 3500rpm is starts chucking out a greyish/blueish smoke, it does the same if you back off the throttle whilst driving then accelerate again it is basically standard apart from an air filter and exhaust i have had all the compressions checked and there fine, it only marginally uses oil heres what i have fitted so far:-

new map sensor
new coolant sensor(blue one)
new plugs, leads, dizzy cap + rotor arm
new charge air temp sensor(brown one)
new injectors (standard 4x4 blue ones)
had the turbo reconditioned
had new valves guides and seals fitted
had full bailey oil seperator kit fitted

can anyone help cos im really fooked off wit it now

 

hi guys just decided to check my phase sensor gap do we rekon this is the problecket.com/albums/y9/bigwhitesaff/000_0810.jpg[/IMG]m?

 

 

 

That phase sensor isnt much cop but blue smoke is oil burning mate, so id be looking at the turbo if the smoke is the only symptom.

 

the smoke its throwin out stinks off juice tho, it hardly uses oil and i had the turbo re conned about 2 months ago, the only other thing is i took the plugs out earlier to check the gap and they are black with soot these are only a week old and the car has not moved its just been started every day, i initially thought it was oil so i had the valves guides and seals done as well as the turbo also had all the compressions checked which are fine, could it be an ignition timing fault ie not burning the fuel at the right time,pics are not very good but the plug on the phase sensor is greenand mouldy also all the insulation had gone off the wires and they were touching the side of the dizzy?

 

anyone??

 

u may have good compression on each of the cylinders but it MAYBE the oil rings on the pistons that are worn so the oil is passing them causing blue smoke out the exhaust m8 is it alot of blue smoke excessive etc? when was it last set up properly?

 

its more greyish than blue to be honest dude, doesnt do it at all when you nail the throttle or should i say if i have been driving it like a bird for a bit then nail it some smoke comes out then it clears and its fine, it does it more on over run ie when you back off the throttle from about 3500 -4000 rpm then go back on the throttle it will blast out some smoke which will then clear. if you rev it up when the cars stationary it will pump out smoke again but when it does this it smells badly of fuel.
ive seen engines before when the rings have gone and its nothing like that.
(hope you can understand this m8!)

 

p.s it seems to have gone worse since i swaped from standard 2wd yellows to standard 4x4 blues

 

yea I know what u mean now, what sort of breather set up u running?if standard maybe it's blocked and needs cleaning out(one under the inlet manifold) or just go and put an after market baileys or spec r type etc!

 

put a ful bailey kit on it about three weeks ago, gonna try a new phase sensor which i ordered yesterday if that doesnt sort it think its gonna be a trip to motorsport deveopments see what they say. ive taken it to a tuning place near me before called RE performance centre but to be honest if it aint got a subaru badge on the bonnet they dont want to no

 

sorry m8 for got ask when did it start to do this?all of a sudden or has it always done it!

phase sensor wont stop what your describing I dont think

 

been doing it for about the last 3 months, it hasnt got any worse or any better. with the insulation missing off both wires of the phase sensor and them both touching the inside of the dizzy was thinking maybe its not getting a signal from the phase sensor and relying on the crank sensor only for a signal, it could be injecting fuel a couple of milliseconds the wrong side of the spark causing it not to burn correctly leaving me with unburnt fuel (especially if my crank sensor is not gapped correctly or full of cack). or it could jus be me clutching at straws delaying the inevitable. what do u think dude - did that make sense?

 

i think the best thing is to pop down to a tuner and get them to check it over for you...!
you have done a lot of the leg work....its time to give the boys with the expensive tools a call and get them to check it before you kill it

pugo

 

sounds good ill get it done next week cheers dude, either that or ill sel it an buy another series 2 - less hassle.

 

never SAW this last time I replied 4x4 injectors (dark blues) are NOT the same flow rating as 2w/d(yellows) ones I'm led to believe so could well e your problem,why not just change them back and see if it improves failing that pro's may be the only way m8 do hope u get it sorted

ps if the phase sensor in that condition it does NEED changing n e ways.

 

just tried my yellows with my fooked phase sensor insulating the wires its miles better but not perfect hopefully with the new phase sensor it will sort it. cheers mate. will update when i have fitted the new phase sensor if ive not burnt it lol

 

Thought that too...

 

ive fixed it finally, the wiring from the coolant temp sensor + map sensor had really high resistance run fresh wires from the ecu to sensors - now sorted
