Good afternoon all, i normally reside over in the X350 section where i have for 3 years loved and modified this



My reason to disturb your peace within, i have seen for sale an R100 XFr, 2011, 75k sale cheap with a cited chain issue but running and driving.

With it driving i am assuming its not got the jumped stage yet?
The bill for the full mashing chain and guides would be circa 3.5k?? Some chat with the owner of the 351 in the picture indicate this to be the invoice figure.

What did the R100 bring to the table over the standard car?

Has any body done this job there self?? im quite brave with the spanners.

Please comment,critique or add to any off the above.

Many thanks

F.C

I think the XFR 100 was a runout model for the Mk1 XF probably just trim and colours.

Sometimes the supercharger coupler rattle gets misdiagnosed as a timing chain rattle.
There was a chap with an XJR x351 which had a skipped tooth chain on one bank. I think the bill was over £4k for that, doing both sides with the newer parts and the extra head work on that one side too. I bet the parts are £1k because I think the newer setup is a wider chain and obviously all the associated sprockets and guides.

A good project though.

Quite a few reports and posts over on the Yank forum about replacing the timing chains and associated parts on the 5.0 V8 across a range of Jags including the XFR.
The general consensus is that it is doable as a DIY but only if you are reasonably skilled with the spanners and have all the correct factory tools and have plenty of time to take it slow and careful.
Also beware it's not just a case of replacing the chains, you also have to replace the chain guides, tensioners and cam sprockets as the old versions are not compatible with the new chains.
Some prefer the old chains as being better engineered than the new ones but it is now impossible to find "new old stock" of them and the associated parts.

Also, while you are in there and especially this deep on an older XFR you should replace ALL the plastic coolant system pipes, tubes and hoses as one or more are bound to crack/split/leak, it's not a matter of if but when they do. Same goes for the coolant pump and thermostat.

I have previously done some research on this when I was looking at early cars using the supercharged 5.0.


Problem seems to be on cars up to about 2012 onwards but doesn't seem to be a definitive way to tell from chassis number.

It would seem that the usual quoted cost to get it done by a specialist is between £3,500 and £4,000, some of this is due to the cost of the 'new style' parts.

The XFR 100 was an 'end of line' special edition prior to the facelift XFR being launched, nice car but I don't think they will become collectable in the true sense.

The dilemma is whether to buy one with the potential issue, pay for the repair and then you know it has been done, pay more for one of the cars the may potentially have the issue in future (unless it has already had the job done) or spend a lot more and get a later car that already has the 'uprated' parts from the factory ?

Out of interest, my friend John is one of our Jaguar 'Master Techs'

He tends to buy Jaguars with mechanical issues that he can fix in his own time and then sell on, making a profit.

Messaged me today about the white XFR 100 that is the subject of this discussion, seller has offered it to him for £7,000.

John already has two XFR's at the moment that he is working on when time allows, so probably not in the market for another.

Information on the sellers 'best price' might be useful, if someone on here is interested in it.

Quite tempted myself at that price but if it needs anything more that the cam chains replacing, it stops being a bargain !

Can't imagaine it would be that hard, the 4.2 S/c is a doddle to strip down, so I'd imagine the 5.0 wouldn't be too difficult.

I'm gearing up to do the chains on my L322 with same engine can't see it being too uch of a ball ache to be fair, you just need as said above all the right kit. ;)

This is the car


I am a little bit dubious about why he doesnt as he says "Book it for the Chain" if this is all it needs,i managed to find another similar car with 6k less miles on auto trader at a trader asking 17k
And now your new best price information makes me even more suspicious,



Im tied atm as i need to sell another orphan just to keep my affairs in order.

Up to £4.5k to do in a garage. Easier to drop engine out and do. Updated kit has a hardened insert on the guides to stop the tensioner wearing through.

Not sure but its no biggie if they can prove they own it

Was speaking with The Jag Specialist in Doncaster and they feel it would be a good bit less.
