It goes from the MAP sensor to a spigot on the underside of the inlet manifold around about the cylinder 5 area. The spigot sometimes gets blocked with crud.
Plastic manifold or alloy?
It would have to be made of extruded diamonds for that money!Good quality spill pipe will do it. Or Silicon vac pipe, even though it is a pressure pipe from manifold to MAP sensor. Actual part number is STC4165 but i don't think you would pay Land rovers £27.00 for a length of spill pipe no matter how good a quality it was.
Plastic.
I'm guessing but I think the spigot on the plastic manifold is part of the moulding. If it's broken off, you may have to fit an alternative.
I think the spigot is still there. Looks like a windscreen washer connector?
Yes, that would be it. Make sure it's not cracked at the base or blocked internally.
If it's working, disconnecting it should make a big difference.
It affects fuelling, there is no direct connection to the turbo.Get a pipe on there will make huge difference if the MAP is ok. Your running without proper boost and these engines rely on it in a P38
2meters of 3.2mm spill you can change the lot and have a spare bit
It feels more like the auto box is changing up when it shouldn't. I'll check the pump anyway, Ta.
Do you have a ‘power box’ fitted?
No box. I was thinking of putting a Ronbox on it but haven't pulled the trigger yet. I'll do the pump test sometime this week if I finish early enough that there's still light.
