Thanks guys,Steve, that would be my question too. In fact, that burn pattern on the pistons looks like 155 deg injector spray pattern on 145 deg piston bowls. Of course timing could also be causing that. Also, that strange burn pattern on the piston top looks like a poor firing injector. The fact of the smoke and rising EGT makes me think the boost isn't matched to the fuel. Too much fuel and not enough air makes heat and smoke but not power.
Injectors were rebuilt less than 3000km ago by a 'reputable' diesel turbo/injector business in Sydney. I also had the turbo(HX30w) rebuilt also but have since had massive issues with oil being fed into the intercooler and intake. was only running 18psi also. Mate told me to check shaft play and has what I would describe as 'excessive' side to side play at around 2mm either way. End play is fine.
So, with the turbo no good(hence upgrade to the HX30 Super) I suspect the injectors could well be rebuilt with 155 degree nozzles, NOT the same as I had originally. Unfortunately with a move of house I can't find the receipt.... I was told they would only rebuild as per standard... so believe they are a 5 x 0.12?? do I check if 145 or 155??
Recommendations on injectors?? Would rather buy new, knowing what I get rather than go through this again..
To be honest, everything that can go wrong with this thing has .... I struggle to trust businesses with doing work for me or on my cars for this exact reason. I just want the thing running and driving.
