I have grey smoke coming out of my exhaust whenever I come to a stop or when ever I accelerate hard what could it be due to. i have changed the spark plugs oil and ignition coils but the problems remain ther is also a slight loss in power but the car still drives ok my EGT on the front housing is at 932'f at idle where as normaly its at 842'f what could the cause be for this.

possible fuel issue? what is your year and setup?

 

Its a Fd With extended Street port,550/1600 injectors,one internal nippon denso fuel pump feeding a surge tank from there it gose in to a aromotive external fuel pump, one piece 3mm ciramic seals, solid coner seals, cryo treated side seals, To4 turbo, NGK 11 all round and the power FC.
I'v got a feeling that it may be the oil seals put not sure so i just want everyones opinion.

 

hmm same thing as having a bad piston ring

 

you sure its gray, as i recall only colors youll get out of the tail pipe will be blue black or white

 

wel its definitely not black so lets say a whitey grey color. isent white to do with the coolant.

 

Yes. You may want to check your coolant level and or have you cooling system pressure tested. Let hope it's not that though.

 

Oil smoke can look white-grey from the driver's seat. Check your oil level - I had too much oil in mine at one point and was getting some puffs of smoke.

Better yet, have someone else rev the engine while you're behind it, and see what you can figure out.

hi guys, i took it on to the motorway Yesterday to see if it would clear up but it actual got worse now it smokes when I’m driving to but I’m 95% sure its coolant now because when you stand behind a friend to see what colour it is you cant actually smell any oil being burnt its more like steam so I’m pretty sure now its coolant so I guess this would mean a engine rebuild I think the warrantee would cover this as the engine probably has less then 4000 miles and is only a few months old. I hope anyway.

Thanks for all the help.
