This might not help given where you are, though I know 3 places in the South Manchester area that would probably do the job: Town & Country Land Rovers (Sandbach) who I know have done timing guides on an LPG 4.4, Land Ranger Services (Middlewich) and I know someone who had it done on a 4.4 that had LPG at a place in Marple I think (could find out if required). I can't believe any of these places would charge more than £1500.

it would be interesting to know, how he undoes the cranknut. you kind of need engine locked, and bolted into the car, to undo it! maybe he has a jig he holds the engine in. but surely it will roll all over the place. might be just an extra thought to check both the rear crank oil seal, and hidden water gasket plate. and be aware he doesnt need to take out the torque converter, it stays in the bellhousing, but is very potentially 'loose'.

as said in previous posts by others and me, its an engine (stays) in job, its rad out, water pump, fan and belt off, alternator off, rocker covers off, upper chain covers off, crank wheel off, cranknut undone, lower timing cover off, and there you are. ready to change all. the whole chain is exposed. lower sump off, to check all particles have fallen down. and then, lock camshafts with toolkit, removed tensioner, then guides, and chain.

Thanks for all your comment and advice everyone. Thanks Zeb for your kind offer job but it's a bit too far away and happy to stick with this engine as it's been perfect so far.

my reference to the torque converter, was just, that, if its badly disturbed, (they can fall out, when engine is out of car...it could start leaking on the gearbox front seal. after replacement. if it isnt at the moment, just point this out, in case it does after. its only a fiver for one, and its easy to fit standing where the engine was. likewise a torque converter, but you dont want to be extending this bill north, so leave it.

I didn't remove the engine or the rad and had loads of room and i would imagine if he is taking it out he will crack the Jesus bolt before removing and tighten after replacing the engine using the locking tool.

Well, after having had my car for nearly a week, the garage finally got started and put her up on a ramp, took the front of the engine off and guess what ?. ... the middle chain guide has shattered.

Was going to get the Valley Pan gasket replaced but am being told there isn't one in these engines, is it completely sealed to the outside elements?

Dolphinboy, if your engine sounded fine up till the chain guide going for dump, then you dont need to change the vanos units. if you had some bad clacking noise, at idling, when cold and still audible when hot, then maybe the vanos SEALS need to be changed. (letting by, as hardened) its a bit fiddly, but the parts and special tool, is £120, and you just need the online guide to hooking them out, and re-inserting. then the strength part, where you have to use a tool, (in kit) to squash the units a bit, (via guide) and then they are good to go again. its quicker but far MORE expensive to just put another set on. but with seals worn, they dont stop working, they just are lazier, and noisier. so, youtube for m62 vanos noise, and rest assured, that you wernt worried before, and your happy to save £900. if you need these done at a later date, its a similar job, to set engine, and remove top half of the covers, but not lower cover, and take them off. chain stays in, but is loosened.

I agree on the vanos, if you were happy before then save £900, they only get noisy and cause start up rattle at worst.
