    Default 2012 Hilux 3.0 D4D Boost Problem

    Hi guys, just looking for some advice or past experiences, I have just had a 3" exhaust fitted on my hilux and since being fitted it feels like the van just lost all its power, it take forever to rev up and can't get over 80kmh on a straight road. I have spoken to a few friends and they dont think the exhaust would've had this effect on the van. Any help would be appreciated.

    Does it smoke a lot?
    Black smoke?

    No smoke at all, just no power. No engine lights either, extremely weird. Not sure if maybe the exhaust guys damaged a plug on the turbo or the actuator...

    I also say i hose is loose somewhere!

    i once drove my bakkie and it made a popping sound , sudden los of power , just like you describe, a hose came loose and rendered the turbo useless, put it back and back to normal!

    maybe check it out bud, hope its something small like that.

    Check if the MAP filter on the vacuum line is not cracked.

    Hi all, so I managed to get the van to a local mechanic and after checking through the system, he ended up taking the turbo off to find that the shaft is jamming between the compressor wheel and turbine wheel. So the shaft hasn't seized as such but if you were to mark a line at say 12 o'clock, the wheel spins to 2 o'clock and back, as if something has fallen in and is now preventing the shaft from spinning freely. They are splitting the turbo tomorrow to see if maybe a nut or some other foreign object has been dropped in. If so I'm not 100% sure on how to approach the exhaust company that did the aftermarket fitment to hold them responsible for the damage as the problem was not present on the van before entering their workshop.

    So this is what the mech found when opening the turbo up, a spot of weld had found its way into the way of the vanes so jammed the shaft from spinning.

    I'm still wondering how they managed to get it up there. Did you replace the downpipe as well.?

    This gets me...it seems to be a syndrome in this country among sooo many suppliers...in various sectors...they want to supply to make money but when there is a come back fingers are pointed elsewhere instead of taking ownership of your mishap...

    Was thinking of it but insurance companies will be involved from Monday, if the matter isn't resolved I'll be happy to. Just know that naming and shaming can also cause more problems.

    He told me he's been in the exhaust game for 40 years and its never happened, as I explained to him, #### happens, it was not on purpose but thats why companies have liability cover through insurance, to cover problems like this. The first thing he did was tell me he's not responsible for it and he will NOT pay for repairs as it was not his fault. 😡

    This is really sad.

    40 years in the business of doing exhausts, says nothing here when such an error has happened and it sounds like he is not accomodating you to solve this issue peacefully.

    Its a shame really and such people don't deserve business at all.
