Puddles Posted June 18, 2007 Share Posted June 18, 2007 I managed to dunk the 90 in a big wet deep silty mud pit last weekend, and got some silt dragged into the turbo through a slight leak in the hoses. It was running like crud, lost a lot of power and smoking bad. When I got home I stripped the manifold/turbo/filter/hoses, cleaned them all thoroughly and replaced them. Car now runs better than ever (I found a big chunk of the old inlet/exhaust manifold gasket was missing so thats now improved), and luckily there was only minor damage to the compressor vanes - a slight polishing and scuffing on the leading edges, no bits missing. I'm getting heavy black smoke on accelration now though, if I apply more than 3/4 throttle. Anything below that is fine(ish), but put my foot down a to the metal and it smokes like billyo Happens when turbo is spun up as well as at low revs. Wondering if there's somewhere else I need to check for mud blockages, or if improving the inlet/exhaust gasket has changed the fueling properties (I've tweeked the pump prior) and now it's overfuelled. Not being lazy, I will go and adjust the fueling oin a bit, but I'm concerned I may have a problem somewhere else Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted June 18, 2007 Share Posted June 18, 2007 I gather the engine is a turbocharged diesel, but which one? Quote Link to comment Share on other sites More sharing options...
Puddles Posted June 18, 2007 Author Share Posted June 18, 2007 Oops - its a 200TDi. Was going to go out at lunchtime and rewind the fueling a little see if that helps, but it's raining in sheets again.. Quote Link to comment Share on other sites More sharing options...
Ex Member Posted June 18, 2007 Share Posted June 18, 2007 Adjust the smoke screw back. Quote Link to comment Share on other sites More sharing options...
Puddles Posted June 19, 2007 Author Share Posted June 19, 2007 ok - adjusted the smoke screw back over 180 degrees and hasn't stopped the black smoke. If water got in the timing belt cover and it got stretched a bit could that cause it to shmoke?? Quote Link to comment Share on other sites More sharing options...
Ex Member Posted June 19, 2007 Share Posted June 19, 2007 Check that the boost sensor line from the turbo to the injector pump is clear. I would pull the top of the pump diapharm and make sure you have a clear line through to the turbo. Are you losing any engine oil? Quote Link to comment Share on other sites More sharing options...
Puddles Posted June 20, 2007 Author Share Posted June 20, 2007 Good idea, I'll check the boost line, might have got some crud in there. All was perfect before I dunked it at high speed into the mud bath on the advanced route at LRW show (wish the marshall who said the safest way across was to "floor it" had also mentioned it was nearly four feet deep and a snorkel might be a good idea...) - haven't done enough miles since to notice a difference in oil level, I'll have to monitor that one.
