Well, after owning my 1974 XJ6 since last June for some unknown reason I decided (finally!) to check the engine numbers. The VIN plate and original ownership papers state that the engine number is 7L82393-S.
The stamp on the LH side of the engine (passenger side as it is UK spec) by the transmission dipstick, clearly states 8L92542-H.
Obviously the engine was replaced at some stage in the past. Could anyone please give me any information on what engine I actually have?
I can’t explain why it has taken me so long to check this basic information!
