Hilux 2.5 2kd-ftv blowing black smoke
Posted: Sun, 07 Apr 2024 4:39 +0000
Hi,
looking for some tech help with this one.
2011 2.5 d4d hilux 2kd-ftv
Engine has been remapped 80k ago. Ran fine after remap. After 12 months its failed the mot on emissions
blows black smoke when either high revving or dropping a gear and accelerating
So far I have done the following-
replaced turbo, replaced injectors (new) relearned injectors and pump. Replaced MAFF sensor, using a smoke machine checked for air leaks. Swapped air box, Intercooler with another vehicle. Removed and cleaned EGR valve (even though mapped out). disconnected fuel filter and ran direct from a make shift tank filled with Weyne’s injector cleaner.
so far nothing has worked apart from running direct on weynes cleaner, that dramatically reduced the black smoke. As soon as I emptied the cleaner and filled with clean diesel it was back black smoking.
No idea what to check now ?
