Landcruiser turbo diesel lack of power

I once had a blocked muffler sounded good and went well at low revs but under load or at speed just did not go, might be worth checking. Will be interested to hear what the outcome is.

Yep.
My 1HD-FTE had gradually been getting gutless. Then it started making a funny noise when you put the foot down at 3000rpm. The exhaust to dump pipe flange is sprung and was popping open from backpressure - could see black marks from this.

What has happened is the cat converter can block up with carbon. Three weeks ago, I replaced the whole system with a 3" exhaust and it has made a huge difference.

Mine did that after a service that included tappets.

they had left off one of the little rubber tubes that run across the rocker cover.

Felt like a 1 HZ Hooked it up and no more troubles

Worth checking as only by pulling gently at each one did I find it.

I had an 80series TD that I took in for an RAC check for a prospective buyer. The guru's that inspected the vehicle disconnected one of the turbo hoses and didnt reconnect it. After this, the turbo didnt kick in and the drive was gutless. Just like yours, it was driving like there was no turbo.

Once I found the loose hose under the bonnet, I reconnected it and the cruiser drove like a dream.

Maybe have a squiz around for any loose hoses.


Good luck

Would be nice if on these type of threads the original poster would come on and

say how they fixed it, if in fact they did.

Rather than leave us all holding our breath waiting waiting waiting..............

i had the same problem with a hzj79. non turbo. it was more gutless than a hj45. the problem was that the previous owners used poor quality fuel filters and buggered the injector pump. reconditioned the pump and injectors and goes much better now. its very costly though. it was so gutless it couldnt run the air conditioner at idle, it clonked out.
i recommend taking it to a diesel specialistl like denco diesel.
