Toyota rav 04 d4d diesel starts & idles ok but won't rev up dosn't show any fault codes. The intercooler on this model sits on top of the engine on doing some checking we find that the large pipe that connects the intercooler to the turbo blows outwards when it should have suction.Has any 1 encountered a similar problem Regards Micky-bo
The intercooler is there to cool air heated by being compressed in the turbo, so it is correctly blowing and not sucking.
Is air actually leaking out of the pipe (in which case that's why you have no boost and poor performance)?
If the pipe is just inflating and bulging, it suggests there is a blockage somewhere, which will also explain why it won't run properly.
