(similar to what LR did with the RV8 crankshaft on the change from the 3.9 to 4.0 engines where crankshaft journals are larger in the 4.0 even though the 3.9 and 4.0 have the same engine capacity.
So clearly PSA/LR/Ford knew of the issues of the crank in the 3.0 and took steps to remedy it for the engine to go into a US stateside product with their Lemon Laws.
I see you own an E Type V12.
Noice car!
Are you aware the early V12 engines had faulty crankshafts and Jaguar had to re-engineer?
Spun bearings often, I replaced 2 in around 1974/5 and they didn't have big mileage on them.
Out of warranty and no 'real' Consumer Laws in those days!
One E Type and one XJ12 Series One.
Never found the reason as I wasn't working for a Dealership, had my own Jaguar/RR business, but heard it was probably faulty nitriding/tuftriding during manufacture.
