reco the injectors. if they have **** themselves they dont mist the fuel they just continually dribble fuel in, which is too much fuel to air mixture. black smoke is definantly fuel. if it were blue it'd be oil. i had bad injectors on my td42, reco them, no more black smoke. could almost be retarded or advanced injector pump timming
RD28T GQ Excessive black smoke
Hey guys i'm asking this on behalf of my friend as he hasn't got the internet and needs a little help. I have no experience with the 2.8 so i best ask. And yes i tried the search with no luck in any threads i looked through.
My mate just bought a 97 GQ 2.8L Turbo w/400,000km, he got it as a run about car but has soo much black smoke pouring out. Changed the air filter and it helped slightly. Pump is in good cond, injectors cond unknown so will pull them and put new nozzles and shim them.
But it still seems to be overfueling and down on power. has anyone had any issues with these motors and smoking? I mean i dont mind a little black smoke, but Cummins 24valve redneck smoke is a little too much.
Cheers
John
