Super fantastic Mod Technical Supremo Nice Guy
What year is the Van,
Until you can get it running on Easy start there is a mechanical problem imo .......................... Easy Start's presence requires air and compression only in order to run ..................no diesel so fuel pump and injectors are totally irrelevantEasyStart won't even get it going!
1. AIT is #8200833248 ................. is that what is fitted? - what is the reported AIT when engine cold first thing in the morning and also when near normal operating temp on the dash temp gauge?Okay guys.
Solved most of this now:
1. I've put the glow plugs from the original engine in as they were nearly new, P0670 is gone now. P0110 remains despite trying a different Air Intake Temp sensor.
2. The injector seat was slightly damaged after removing the old injector washer, so I've recut that injector seat and put a new washer in. I thought I still saw smoke afterwards but I really can't tell now! Maybe it's sorted...
3. It split a hose near the turbo, hidden away behind other stuff. That's been replaced and it sounds better now.
BUT, AS ALWAYS, WE HAVE A NEW PROBLEM!
4. This engine had very little blow-by when it was on the previous vehicle, I'm pretty sure opening the oil filler cap when it was running didn't previously splatter oil in the vicinity, and I think there's some exhaust/combustion gas coming it. It sounds like an exhaust!
I've checked the main breather hose (which has the Air Intake Temp sensor on it) and cleared that out. I've also removed and cleaned the EGR valve etc. Still the same. So I did a compression test:
- my gauge runs out at 20 bar (it's for petrols...) but looking at where the needle goes after 5 cycles each cylinder is getting 25-27 bar (cold). There's no meaningful difference across the cylinders from what I can tell.
I'm starting to run out of ideas!
The oil leak is from the Turbo Oil Return pipe at the sump end!
Its NOT crankcase pressure IMO - Only one way to sort this - redo the plumbing and seals involved till no leak.I can only assume it's the crank case pressure.
