The more I think about it the more I suspect something else isnt "right".
Aftermarket
Ecu
550cc injectors
Td04.
Even at 1.8bar, a Td04 isnt going to milk a set of 550's.
Maybe it was tired to begin with. Where did the motor come from Luke?
It runs a FMIC, so it hasnt had thermal loading issues. I know how it was being driven just prior to its fire, and its death, and that sort of driving wasnt hard enough or prolong enough to kill a motor.
So what kills a motor? Oil issues... if it leaked all the oil out and did a big end maybe, but thats not what it sounds like...
Sounds more like its done a ringlind, blow by has put oil into the engine bay, causing the fire.
Either way its fucked.
Heres my "ifs"
"If" it wasnt tuned above a certain level, lets say 1.3 bar, cos thats what a stock td04 is going to flow happily, and its ran 1.8, its dead, and if it had overboost programmed into it, and it didnt work... well the reason it didnt work is to blame.
"if" the motor was already dead no ones to blame.
if a fuel pressure reg or injector failed, whos to blame?
Sorry for the wierd post, Ive been sitting here for an hour thinking aloud. Writing them down was meant to help me sort it out in my head... its not working.
