So recently I had a td4 engine replaced on mine it was at 160,000 and although I cannot say for sure exactly what it was that went I do know that once we took it out and turned with a breaker bar using the crank shaft pulley something went *clunk-snap* and then seized solid.
Since getting the new engine at 88,000 miles and having it fitted we noticed only afew differences first the modified fuel rail pressure sensor loom was not on this engine, second the MAP? sensor on the intercooler pipes at the front was non existent and no wiring for one either (retained loom and other assorted parts from old engine.)
My power loss seems to be between 1000 to maybe 2250 rpm ish I believe this is when the turbo kicks in but was under the impression the VNT turbo worked below 2.5, I have checked vacuum lines replaced all and swapped out boost valve including checking the actuator moves by putting my hand up there (don't do while hot).
I don't feel the pipes swell when revved until what sounds like quits high in the rev band maybe 4000 but can't say for sure (women on throttle) I have no whistling and can't see any boost leaks either I can hear the turbo at around 3000 aswell.
Any ideas from my uhh brief description what could be the cause oh and a EGR is fitted to this new engine not yet removed.
