I am looking for an Arnage and there seem to plenty of T available. However, I am aware that there were tappet and head gasket problems in the T versions. One seller is suggesting that these problems only affected the early T, but my own research suggests that the problems were not eliminated until the 2007 model. Anybody know the full story ? Finding a car where the remedial work has been done, with receipts, is proving difficult.
Many thanks for any help you can provide.

Yes, tappets are (or can be) a problem on all cars prior to MY2007.
Bentley re-engineered the complete system from 2007 on together with lots of other major improvements.

From the press release :

Overview
-Uprated 6.75-litre twin-turbocharged V8 engine in Arnage T produces 500bhp and 1000Nm torque, thanks to new low inertia turbochargers and roller tappet system. Arnage R and RL models uprated to 450bhp and 875Nm of torque.
-Latest six-speed ZF automatic transmission with sophisticated locking torque converter provides fast yet ultra-smooth gearshifts.
-New Electronic Stability Programme (ESP) logic system improves dynamic response and handling with less intrusive intervention when a reduction in grip is detected.
-New Tyre Pressure Monitoring System fitted as standard to all Arnage models.
-Improved driver ergonomics thanks to 25mm increase in length of steering column and in vertical steering wheel adjustment.
-Exterior design styling changes includes new dark finish to Arnage T front radiator and bumper grilles, standardised bright chromefinish to R and RL grilles, and Bentley ‘B’ badges on the D-pillars.
-Underbonnet styling now features a black crackle finish to the Arnage T’s inlet manifold, embossed Bentley logo on plenum chambers and new ‘6¾ LITRE TWIN TURBO’ engine plaques.
-Interior design updates include new hide-trimmed gearlever and chrome gearlever bezel providing access to semi-automatictransmission function.
-New Thin Film Technology driver information panel displays more comprehensive and clearly accessible information.

Thanks Denis, this is much as I thought. I don't think the Arnage R had the same head gasket and tappet problems of the T, and I'd gladly have the R if I could find one. In that way, I'd avoid buying a car with a looming problem.
best wishes,
David.

You are most welcome. However please note that R and T prior to MY07 have the same problem.
Engine layout is the same.
If possible you should go for an R or T from '07 on. That's what I did and could not be happier.
