Crossflow Engine Number

Does the crossflow have a unique engine number - I assume the 711M 6015... one is the block type with a two letter suffix describing month of manufacture - is this correct?

Does that mean the unique one to be registered on the V5 is the 4 figure one under the alternator bracket?

No - that's not the unique number, that's the type code.

Look at the top of the block, next to the head gasket, just next to the exhaust manifold. You will see a little 'bump out' which should have a few letters and numbers stamped untidily on it. That's the engine number.

cheers,

David

The suffix is what size of block m8..

AA is 1.1 or 1.3
AB is 1.6

I assume from that then, the engine number should be
on the horizontal face of the (upside down) bell shaped
lug next to the head, above the alternator bracket.
There ain't one there!!!

1: I know it is a pre 1970 engine 'cause its block number is
681F-6015-JA does that mean that Ford didn't bother individually
numbering the blocks in those days? (I don't believe there is any
dodgy history to it)

2: What does a JA suffix tell me?

3: What is the format of the serial number, should I need to 're-create
one?

Thanks in advance,
Andy

OK - plan B!

If there isn't a number on the top of the block (and it's usually quite plain to see as long as it's clean) it may indicate that the block has been skimmed at some time in the past.

Good engine workshops will re-stamp the number somewhere else, typically on one of the lugs near the end of the block.

Don't stamp your own number without talking to the DVLA, as they keep a register of numbers.

i needed a number on one of my previous cars engine as the number had disapeared overnight

I went to the breakers yard, found a similar engine waiting to be scrapped, jotted the number down and duly stamped that number on to my block

Good idea, visit to the scrappie for me!! Hope I can find a crossflow, suppose I should find one in an early fiesta.....

Can you just use normal punches - no problem stamping a cast metal block is there (it's brittle nature and all that)?
