Hi

Are you getting much extra exhaust smoke?

I had an issue with my land rover a couple of years ago. I lost power when driving along the M5 - dropped down to around 20MPH top speed - which was an issue!

I checked the air filter - fine - and did all of the basics. Eventually I noticed that the hose from the turbo to the inter cooler seemed to collapse under hard acceleration.

When I looked inside the hose from the air filter to the turbo, I found a flap of material had half torn off, and when the airflow reached a certain point, the flap blocked the pipe and therefore reduced the power. It took some hunting for, as when there was no airflow, the flap popped back out of view! So the flap was acting as a power limiter.

A knife, some gaffer tape, and I continued on my way.

Hi henry cheers for the reply. i not long ago changed my turbo hose and it did help, i was actualy get a proper boost out of my turbo rather than half boost.

i noticed that if i was to leave the engine idle you can hear the engin having a bit of a strugle for fuel. there is some smoke but its grey smoke

Have you checked the leak off pipes betwen the injectors for splits, if they let air in it wont run propper.

not from what i know mate, the handbreak seems to be working sound. unless its not coming off properly and its rubbing on the inside of the drum. is there any way i can test it or would it invilv me taking the drum off?

cheers

choke the wheels, hand brake off, and rear wheels up, it should spin freely

landowner · Jan 18, 2011

Just one more thing to check and it's cheap....there is a small filter inside the banjo bolt that bolts the fuel return pipe to the back of the pump. Worth taking it out and cleaning the small gauze filter inside the shank, it's only small.
keep you busy.

when the wheels are jacked up off the dloor i can spin the read wheels freely with my hands. dose this rule it out?

[JP] · Jan 18, 2011

yep, if you can spin the wheels, then the handbrake is loose..... rule it out

Yes...ruled out.
Just a thought, is your throttle cable ok, not come loose or owt, just get someone to press it and make sure the lever on the pump goes all the way

The Mad Hat Man · Jan 18, 2011

no it dont. If both rear wheels are off the floor - if yu spin one wheel, does the other one spin in the other direction?

Your right,...thought someone said one wheel up though.
