Hey all,
new to the forums here...
I got an LN-61 with a 2LT, recently i failed my last wof as the diesel pump was leaking fuel from the idle control thing..(the wax thing with two water lines)
I called diesel n turbo in Seaview (wellington) and they sold me a small plate and new oring, which replaced the whole idle adjusting part.
So i removed it, and put the plate on, voila, no more diesel leak.
However, now it seems I have lost a fair amount of power.
Is there anything that might need readjusting after removing the temporature idle control device? I saw it had a shaft inside it, is it possible i have left part of it inside the fuel pump? I could not find anything else..
there was a spring, a nut, two pieces of metal on the outside of the spring, the housing, and a shaft inside the housing.
The shaft inside the housing looks like it controls something inside the pump, which is what I am thinking might be the problem.
My workshop manual doesnt really go into any detail on the idle control device.
Thanks in advance for any help.

2-LT power loss

Pm Taz01 he has some 2Lt parts handy
70 series prado (KZJ78) and 90 Series Prado (KZJ95)
Re: 2-LT power loss
afaik it basicly just ups the fuel when its cold. possibly alters injection timing as well.
however often the wax element fails/jams. power loss when removed? check timing and also max fuel setting.
is the half throttle power still about the same ?

Re: 2-LT power loss
I swapped two hoses around, and it appears i have the power back?
the vacuem hose which runs over to/from the alternator to the fuel pump (connects to a round flattish thing) and the pipe from the back of the intake manifold etc.
Seems to have restored power, though I couldnt see what one of the hoses would do other than measure boost perhaps? (connects to the sensors on the aircan)

Re: 2-LT power loss
the hose to the round thingy on the pump should come from the inlet manifold, usualy tee'd to boost sensor or boost switch (depending on year etc).
