I’ve got a turbo diesel 5l hilux - A 3.0 litre with after market turbo.
The setup has run well for many years but I’m now on a trip and something is amiss.
The car is down on power and is sluggish right through the rev range. There are very few other tell tales. It was ok last week and I’m out of ideas.
It’s not getting hot.
Doesn’t appear to be blowing smoke.
No new noises
Still boosts ok - at least to about 9psi which is all I’ve ever asked of it.
The only real difference that might be a clue is that compared to previously the boost is higher for the same speed. So it’s like the motor is working harder. It does feel like I’m having to be heavier on the throttle. Previously at 100kph it sat at 4-5psi. Now at 85kph it’s doing that.
I did have a new free flowing muffler installed last week but I can’t imagine that is it. I’ve checked the air inlet and no issues there. Fuel filter recently replaced. Fuel tank run to empty and refilled. It just feels restrict.
I have a new fuel filter to put in to rule that out but 99% sure that’s not the issue. I’m thinking it’s either fuel or compression related but just guessing really.
Any ideas very much appreciated.
