I'm fairly out of my depth here, but -

• vehicle has been off the road for a while getting turbo rebuilt etc
• does a few short (3-10km) trips
• 4th trip at 17km - problem occurs
• try to turn over engine starter rapidly clicks
• Can be turned over by hand

My guess like others is a flat battery is problem number one, short runs with not enough time to recharge and then leaving ~ 75w of lights going for 3 hours = flat battery.


As for what else may have occurred internally, well that's out of my league - but good luck.

battery was flat. Got it to turn over once or twice with some sub par jumper leads and the neighbours truck. Battery is now on charge, thanks to the neighbour. I dont own either jump leads, charger or a multi meter.....

I wont get a good go at starting it till the morning.

I can understand why Dave said "incorrect adjusted turbo" as he knew I had just taken mine off to fix the actuator to vane control rod/pin/plate. With what I have to go by, it was pretty close to stock setting(as close to I could get it with the info at hand) The car drove well and "as normal" with this setting.

but why would the throttle be stuck?

It is however 100% that there was a minimum of 2 litres more oil in the sump than MAX on the dip stick.

as for why didnt I brake it stop......well lets see, why didnt I fill it correctly? Why didnt I drain some oil when the dip stick was indicating it higher than Max? Why did I choose to do an oil change instead of doing the Stand Up Paddle ocean race I was going to do? Why did I date that crazy scotish girl with fake boobs???.....well i guess that can only be answered by those with more intellgence than me as im just the stupid guy right......

btw, would braking to stall it out really have stopped it.....I dont think that will ever be known and Im not going to recreate it to find out.

The turbo time will be removed, it is not needed.

If you had it in 5th (even 4th) and the clutch was in good nick and the brakes were good yep you could have braked it to a stop

I think you mean you dont want to recreate it to find out. A runaway diesel is something you need to know how to deal with and anything goes dropping it into a tall gear and jamming the brakes, firing an extinguisher down the inlet, hosing the air intake or just running away.

By the time you get to dealing with a runaway you're no longer really trying to save the engine, you're trying to limit the collateral damage.

Have you checked the condition of the lift pump? you may find that part of your original lack of power problem is a leaking lift pump thats gone from aerating the fuel to dumping it in the sump, the fuel pump on a landy shifts in the vicinity of 1.5l/min@7psi@1000Rpm if you were leaking even 1/4 of that into the sump it would only take it 8 minutes at just over idle to cause enough dilution that the oil begins aerating on its way out of the big ends and main journals not to mention the additional fuming it would receive from trying to cool the under side of the pistons get it juuuust right and you can wind up with an in crank case fire which is nothing much in a small turbo diesel but its not doing any of the metals inside the block any favors. After about another 8 or some minutes in the same conditions the balance weights on the crank and the bottom of the big ends will begin splashing into the surface of the "oil" from here disaster is pretty much inevitable.


(I have always wanted to see a cathedral diesel do a runaway)

Ive got plenty of schedule shuffling going on and ATM am starting to stuff things into the W/D evening, if you want I can clear you a spot, drop me an accurate location and if something is on near you I can come out and lob the MK II's around if you need it.

Obviously "Idle Holds" would be as well then!


Cheers, Mick

partially because of the number of incidents caused by people who were not aware of them dumping the clutch with the engine running and the vehicle in gear, partially because some installations bypassed engine safety gear so the inertia cut outs didnt.

I don't know if Serg could've braked/stalled it at 80km/h/full noise ?

I know I couldn't with a throttle jam on a race car once.

Big stab of the middle pedal did eff all, but I was at 6500RPM in top gear at the time.

not quite the same amount of power available from the rover diesel though and brakes rated to pull up nearly 7t from highway speeds... at the bare minimum it would have bought him time.
