Technical Throttle body at it again 😒

[Steveetee55]

Well as i assumed might happen, it has, the throttle body on my twin air is out of sink again, fortunately i can relearn it now, as my multiecuscan is working, which im 95% certain is due to the cold side turbo seal weaping, as when i checked the inlet pipe to the body was wet last october, hence why i think its using oil, so i need to strip it all down clean out the throttle body the inlet pipe and the intercooler fit a new cartridge and check the turbo oil feed pipes, its not smoking, pretty sure when i take the pipe off the bottom of the intercooler its going to be full of oil so tray will be at the ready, ive notice in the last couple of days it was running lumpy on idle..

Eh up steveetee

That’s a PIA

Keep us updated as to when your thinking of having a go at this

I’m interested as I’m going to have a look at same on mine although it’s not the same level of symptoms you’ve got

Out of interest what problems do you have and what sort of mileage has your old girl done mines just done 50k, mine is definately getting residue in the inlet upto the throttle body, ive had a delve into this engine and it does have pcv/oil seperator its built into the rocker cover provided mrs tee doesnt have other ideas, i will take it all to bits check cold side of turbo and give it all a clean and drop any oil out of the bottom of the intercooler, if the turbo does have play and looks wet i will get a cartridge ordered and clean or replace the turbo oil feeds

Eh up

Mines a 21 plate with 35k, I do need to give it a full service which it missed last year as rebuilding a house so focus was on getting the shell watertight and ready for winter.

If I’m critical I think it’s:-

Using a little oil ( although all mine have )
A little residue on the chrome exhaust tip
Slightly lumpy on cold start

it’s not smoking and runs sweetly when warm, it might just be my suspicion but definitely I need to settle my mind.

I don’t think it’s turbo but equally if I apply the same logic as you are the only real way to be certain is strip check.

i know the signs with mine runs lumpy on tickover which is what it did last time when threw an eml light went into limp mode, started get lumpy in tickover 2 days ago and stop start stopped working then low and behold went into limp mode tonight on the way home' i had my laptop in the car throttle body fault code so i just cleared it and finished the journey home, but i want to strip and clean all inlet to the throttle body and the body 1st take off the pipes into the turbo and see if its wet in there and has too much play in the turbo, then i will do the relearn and order a cartridge if necessary, i read that mitsubishi td 02 turbos can suffer with seal problems, mine had 40k on it when i bought but if had been serviced to the silly fiat18k service interval or the previous owner hadn't been gentle with the turbo letting it idle a bit before turning it off, plus i do short choppy journeys in it then it may have added to the turbos demise, the inlet into the turbo from the breather and airbox is dry which in my train of thought is if it was high crank case compression was that would be wet, i'd like to think a 50k engine shouldn't have that problem i don't thrash it and the engines had regular service with correct oil and filter put it this way i will be p***** off off if that is the problem that would be a sorry state of affairs, my experience with italian cars i,ve owned have always had good engines' electrics have always been there achilles heal

Update took off throttle body, maf sensor breather hose, clean them all out with non greasy contact cleaner, was a bit of oil in them but not a mega amount, never got to drain any thing from the intercooler spent an hour p×××××g about trying to get the throttle body to relearn, coming up out of range but showing learned in parameter then it came up the clutch need a relearn, sorted that clear fault codes tried a manual relearn procedure, took it out for a test drive about 10 miles seemed ok but, will take it out again tomorrow as until its had a proper run i wont trust it, i don't know how much oil residue should be in inlet but if its a pcv issue the rocker cover will have to be removed as its in there with all the b,s there will be to remove it, the timing chain cover does have a leak but its not that bad,this little car is pushing the wrong buttons with me at the moment in the old day i would have got rid by now

Eh up lad

It’s worth keeping these little cars going , there a proper PIA I’ve had them from Mk1 to now , but love them.

If you need a hand with owt let me know, I’ll gladly lend a hand.

I’d leave the timing cover , mines got a slight weep but used my endoscop to view and it ai t worth doing.

Re the PcV , interesting point, like you I be tempted to get it out and flush with carb cleaner or similar, just in case.

I’d be happy with your results overall, see how it goes on the next run.

Cheers

Thanks i will if needed, trouble with the pcv is not so much the cleaning, but having to either remove the inlet manifold, or cut the bracket from the inlet manifold to the rocker cover, you cant remove inlet manifold without removing alternator, aircon pump etc, i think it would still be a fiddly job, silly design really as pcv in need of flushing isn't an uncommon occurence any how lets hope its solved for now
