Alfa GT problem
Afternoon All, you guys have so far been able to resolve all my problems, so im back again to try my luck....
Alfa GT 1.9jtd 102k. it is smoking from the back end, I know I know this one has been covered loads and I have read lots of threads but i just cant seem to sort it out.
now I know it will ploom a bit if i floor it which is fine but i was following my car the other day and it is kicking out a dark smoke way more than 98% of other cars i follow. im not talking plooms all the time but an example of the amount of smoke is when you follow a car that has just started up on a really cold morning.. that amount ( but not white as i say its dark) I have noticed it when reversing that smoke will be blowing past the drivers window.
Anyway, I have checked the hoses I can not feel any splits in the pipe at all(had aright good feel and cant feel anything) but the bottom hose was a little oily on top. ive had the egr off and it was surprisingly clear (just a light dusting so think it could be a relatively new unit)
what i did notice which was odd was when i opened the air box at the bottom there was a bit of oil inside....odd
anyway back to the smoking the car is performing as well as when i got it ( smoking same when i bought and did not notice untill a couple of days after I got it home., so would not know if its underpowered) but there seems to be plenty of power. I did notice that the throttle mechanism had been bent at some point meaning that it could never fully open by 5% so bent it back.
guess my questions are
1 even though i can not find any splits should I change the hoses if they are the most likely culprits,
2 where is the map sensor and should i look at cleaning this?
3 what else can i check with out starting to buy lots of expensive parts in the hope it cures it.
its MOT time in a month hence getting my ass into gear and looking at fixing the issue....why i never took advantage of the summer months i'll never know as ill be working at the side of the road.
thanks in advance for your help guys and if you have any pix of any suggested check you make it would save me lots of hunting time
