Been a while away from this forum, good to see it's still going strong!
I still have my trusty mk5 smiley, and managed to fit a reconditioned 2.5 banana (without the banana manifold) turbo engine into it. It's served me well over the past few years, but now it's just too smoky... black smoke!! So much that it won't pass its MOT. The engine was modded by a professional to get to work in my van, which included overriding immobiliser, blanking off the EGR, disabling a few of the butterfly valves and routing some of the pipes. All the obvious stuff has been done - air filter, fuel filter, checking the inlet manifold (oily inside - but generally not coked up).. I'm a bit reluctant to add any additive to the fuel. I know black smoke is a fueling issue, so perhaps not enough air...or too much fuel (maybe fuel pump needs adjusting).... or perhaps a problem with the turbo?
It does seem to be a bit low on power these days compared to what it used to be when the recon engine was first fitted (which ran like a dream with little smoke for ages)... I have worked the van REALLY hard over the past few years, so I dunno yea, maybe I've worn something out. Ive heard splits in the pipes can be a problem, so going to check that next. Or I was wondering if a problem with injectors (which were all new when fitting the recon engine)
any thoughts on this would be much appreciated!
many thanks
