Hi,

Just looking for some answers to a problem that I am having with a 1HZ 2001 100series standard diesel Landcruiser. Or if anyone else has had a familiar problem.

The problem is a loss of power occurring when you give the car a bit of acceleration and it generally occurs at around 2500 r/pm through any of the gears. It is really noticeable travelling up hills. There is also a bit of a smoke smell associated when trying to keep the revs up going up a hill or through sand etc. So far i havn't visibly see any smoke, but am sure i have smelt it. I have taken the vehicle to my local mechanic and he believes its a fuel pressure issue and wants me to take it to a diesel specialist. The car has been brilliant up until now. I am not sure when exactly the problem started. I only recently had the car serviced and havnt taken it anywhere since, other than down the road to the shops etc where the problem is not really noticeable. It only really becomes apparent when you are giving it a bit of 'stick'.

Any advice is appreciated. The car has 277 000 ks on the clock. So far all in line filters(that i am aware of) and lines have been checked and are clean.

Cheers in advance,
Matt

Mat, have you had your clutch checked. Sounds like it could be slipping when you give it the stick.

At 270,000 odd km you probably need to have the injector pump overhauled. It will cost about $2000.

Matt,
Have you ever had the injectors replaced or serviced?

No they haven't had any attention since I've owned the vehicle for the past
40 000k's. I think thats about to change! Could they be clogged or dirty enough to cause the power loss?

Yeah Matt,

The pintle style injectors fitted to a 1HZ or any other pre-combustion design diesel seem to lose their ability to atomise the fuel sooner than direct injection needle types. I'm not saying the pump may not be in need of attention but I would get the injectors at least tested first.

I had an unusual problem with mine with similar symptoms which ended up being a blocked snorkel. Sticks & leaves had got caught in a bend which allowed sufficient air for normal driving but when under load the restriction caused reduced power & excessive smoke. Not till we had it on a dyno was it noticed the intake hose was collapsing under accelleration. I asume you've checked the air intake & filter?

I had aproblem with an almost identical motor. My whilst in low gears and giving it stick the revs would suddenly 'collapse' and then slowly pick-up again.

The suction side of the aftermarket turbo - rubber pipe lining would get 'sucked in' a new rubber pipe section solved the problem.

Yours sounds like a clutch slip - particularly with the smell.

Hi all,

I certainly used to have an issue similar to this with my old 60 series and its 2H motor, when it dropped off the top of the torque curve as the revs increased.

Engine speed would keep increasing, albeit slowly, but the old girl felt like she wouldn't pull the skin off a rice pudding!

Other possibilities might be a partial blockage of the fuel line - possibly solved by blowing air backwards through the line back to the tank(s) and re-priming everything - you can clean the tank then, at your leisure, if this solves your immediate problem. Or possibly a problem with airflow to the pre-combustion chamber, like a soft air intake hose sucking partly shut - happened to me with an old 4 cylinder Chrysler Centura.!

No expert, here, but have had all three issues at different times.

Regards,


Charlie
