A jumping chain would certainly explain why it appeared to run OK and then suddenly developed issues again.

The oil in that engine looked pretty manky. Maybe the chain tensioner didn't operate correctly on initial startup, it jumped a tooth, corrected by your tweaking of the pump timing, only to jump again...

You need to have a look at that chain, methinks.

Both nightmare jobs. Either way, you have to take timing chain off, so my bet is scrap it and call it a day.

I feel that way. But I have £1500 tied up in this - more than I can justify writing off -  so need to minimise loses now, which I guess means fixing the thing.

according to oracle, pump is easy to replace as pump has master spline which means it can only go in one way. pulley stays put held by special tool  which i can get.BUT my vote is remove engine swap heads and reinstall

Could this be same thing?

Dunno if Disco's have the BMW lump in them  :-/

But my bro's 2.5 TD did the same as that article......it wasnt the timing chain....it waz summat to do with the pump and had a new one fitted.

Well it might not have needed one  :-/ But thats what you expect when he had it recovered to a main stealer!

Chains/Sprockets/Guides appear to be dealer only.

Just rang the dealer....   ...assuming tensioners OK, looking around £235 + VAT....  

Tensioners an extra £62.50 + VAT each if they are gone.

I'm still hyperventilating.

Either 4 cyl descended from the early Diesel or the TD5

Eurocarparts are cheaper......

Going by their website, might be able to nearly save the VAT, though nothing in stock....

do yourself a favour, how much is a head gasket (not set just head gasket)?

That must be a Wiltshire/Avon term for something, coz means nought to me, but think I can guess the meaning....

Just rang the same place I got previous HG set quotes from.  HG is around £60/£65, but need to know how many 'notches' it has, which is something to do with thickness??  They are now saying they don't list bolts, which usually mean they are not stretch bolts
