Timing chain broken on that side, lack of compression, also bent valves, lack of vacuum assistance to brake servo.
very suprised they cant pick that up, mind you I bet no one ther has ever seen one before.

No, which Ford dealer are you using?

Yeah sounds like your chain has jumped a few teeth or broke on that side. If it's broke you would also have very little power & engine would be very rough.

What Ford say refers to the Mk3 24V not the later Scorpio 95+

The garage is called Hartlands ford,but there you go!The engine does run rough so if it has jumped a few teeth maybe it has,nt bent valves.the garage also say the plugs are wet.but if the timming is out maybe they would be.

how easy is it to change a timming chain on these,also I may as well change the timming chain tensioners.

Yes John I saw that.

There is a Granada Scorpio 2.9 24v Cosworth though which people often confuse with our 95-98 Scorpio

Mark

See what damage you have done first & then price it up first mate.
You may be shocked.

If you still want to do it there is guides on the main site.

At the very least a new chain, sprockets & guides for that side is gonna be about £250+

To do a proper job you need to do the other side also, you have to remove that sides chain anyway to do your bank >:(

Alot of money even if you do it yourself.
