    That's about 75 lbs/ft I think, in old money.....pretty high really! Is there another mounting that bolts on to this one? Can't say I recognise it.
    Thanks for the pic! We await the results with anticipation - but I guess the belt is on now?

    Maybe, maybe not Motman.

    I can send you links to the parts and tools I've bought if its any use to you.

    If you look at the logbook and get the engine code, I can post the diagram of the belt change procedure if its listed in the app I have.

    Job is on hold til the replacement bracket arrives which I'm advised, has been shipped.

    Here's a picture of the full engine mount assembly -

    Looking at those first pics again, I'd guess there had been some sort of electrolytic corrosion set up between the steel bolts and the alloy casting, causing the alloy to 'pick up' on the bolt threads....the stripping actually takes place when the bolts are undone, and there's nowt you can do to prevent it, unfortunately.

    Perhaps coat the threads of the new bolts with thread lock?

    Sure - although I've never had any come loose the new bolts may be treated for you already......often a blue or red dry substance on the threads. If not, it sure can do no harm!
    Do you suspect the car has had interference in this area before? Just wondering if it had a clutch job or whatever in the past.

    I was thinking of thread lock to impede electrolytic corrosion as I'll have to take the bolts out for the next belt change if the car lasts that long.

    The bolts I took out weren't the originals as confirmed by VW when I took them along for matching against the new ones.

    The service book has a record of only one belt change at 27k so the belt I've removed has done well to get to 104k.

    So, those bolts have been tampered with before - but 27k is a bit on the cautious side!
    I reckon around 70k, and the ones I've seen showed no distress at all.

    Thanks for the offer DIYspanner but I have an Autodata cam belt book and a whole workshop of tools at my disposal. I have done literally hundreds of timing belts in my time but I always seem to have trouble when doing anything on my own cars! Ours has only done around 25k since it was last changed (inc. water pump by a main dealer before we got it) but that was over 5 years ago and they do recommend every 4.

    Our Evoque has a recommended timing belt life of 10 years/150,000 miles!

    My old Citroen C5 2.0 Hdi had the same intervals but no-one dares to test it out .

    One thing about doing this job is that the camshaft pegs in the tool kit I invested in didn't fit in the camshaft sprocket locking hole. Slightly too big.

    I had to use a drill bit.

    What do you expect for £10.99 ! The basics are there though

    What I expected was that the kit would do the job.

    It may be a diy priced and not up to daily use in a garage, but at least it should fit.

    Ironic how the more complex tool, the crank lock does fit but a simple pin tool doesn't.

    Might I ask where you stand on motors with unkeyed crank/cam sprockets? Ie, do you loosen the sprockets and time up fresh each time, or leave the sprockets bolted on and mark them up? The differences in opinion seem polarised, to say the least! I'm leaning towards loosening the sprockets as the best method, but I haven't done hundreds of them.

    Just butting in here but I lock everything up - and I mean everything - and then its sprockets off. I'm fortunate that I can borrow some locking kits but its not a job I can make money at so I rarely bother now.
