    there's something else inside the right hand one doesn't look like trailer stuff. My owners manual says it's under the front right seat , which it isn't. Where it would go in the boot I just have two empty spaces meaning a big boot.

    I've never ran LPG so I can't really comment on it. For a V8 I don't thinks it that bad on fuel , well it's better than my dads l322 4.4 petrol ,fuel gauge moves more than the bloody rev counter.

    I have heard lpg can ruin engines due to the gunk , similar to what comes out of a forklift.

    Which I imagen with a torque cam , it's almost definitely going to need shimming. I may try to contact a local specialist closer to the time , to see wether I could get them to come out and check for me.

    I'm an amature mechanic at best , how difficult is it to do the cam? I've purchased some land rover workshop manuals to try and teach myself, so I have a minor understanding.

    I have a 4.0 1999 P38 , I am looking into getting the engine tuned and was wondering is it worth waiting until I have changed the camshaft for a torque cam would it effect the tune?
