Kick down cable may need a tweak... is it seeming to have a delayed

If it is kicking down but still pants it could be just wear.

Any camshaft noise...ticket tick when cold was the give away on my
first V8.

Other thing would be to run a compression test wo see if all is
well.... I can't recommend these enough at the mo...endless fun!

Snot got the diff stuck on has it? May explain both problems.

Yup, if all else is OK I would suspect a worn cam. If they are not properly
lubricated, they can be scrap (performance wise) in 80K miles.

Fitting a new one is a reasonably easy job and not too expensive.

Would cam wear bring it down on power? Had the horsebox on yesterday and
didn't notice it was on - which compared to the L200 (mitsubishi) which
struggled is rather good.

Yep, sure would. I had a 3.5 fitted to the 90 and it wasn't very much
better than the 2.5 n/a it replaced. When I rebuilt the 90 as a trialler I
did the whole top end of the engine and fitted a 3.9 cam. BIG difference.
The old cam was like a steel bar with a few lumps on. The 3.9 cam (same
quoted power, but supposed to have better low-speed torque) had actual cams
on it. :-) If the cam's worn (and they do), then the valves don't get
lifted up far enough or quickly enough, and the engine breathing suffers.
It's a known problem with high-mileage/badly maintained V8s (I suspect mine
was both).

if it's working right, the viscous is only noisy for about the first 30
seconds anyway.

>kick down?


drive it at about 55, and floor the throttle, see if it changes into 2nd. If
not, then it's not getting enough kickdown :-)


make sure the throttle cable isn't slack; make sure there's not an inch of
mats under the throttle pedal.

have an "assistant" press the pedal to the floor (engine off, natch) then
look under the bonnet, see if the thottle is fully open and examine the
kickdown cable to see if it can be pulled any further.

If you disconnect it and pull it by hand, you'll find that it pulls out
against a spring and seems to stop; if you pull it more it pulls out a bit
further and then really stops - there should be a distinct "step" in the
feel of it. This final stage is the full-blown kickdown and the cable has
to pull that far at full throttle. The only thing you can get seriously
wrong by fiddling is to get it adjusted so tight that the kickdown cable
hits the final stop in the gearbox before full throttle - this is bad, and
can bugger things up internally, so don't do it.

Going back to the previous para., if you can get at the kickdown cable while
holding the pedal down, see if you can pull it further, if so, try
tightening it.
