Alex mate, you need to pay attention better
we're on about the 4.2 diesel engine in the Y60 Trols which
will run on anything and uses timing gears, just like the 2.7. It will also transplant almost straight into a 3.0 Y61 Trol if you have the time and money (same drivetrain so move a couple engine mounts and away you go) :naughty
I think you are thinking of the 3.0 diesel in the Y61 Trols like mine. No it won't run on veg but as I've said (until I'm blue in the face
) it's not a normal chain cam engine, it's a hybrid gear/chain, and the chain is so underused that it will never need touched (and that's coming from the guys in Aus who seriuously know their stuff). The cam chain argument don't work.
The (prematurely failing) DMF argument does but you won't get that with a 4.2 Y60... (and you can fit a solid conversion to the 3.0 anyway, like I did).
