Have a spare 1.6 ford Kent crossflow engine block and trying to trace where it originally came from.

Not sure how to post photos but it's stamped engine number is: UE12493

These engines were stamped with the chassis number of the car it was fitted to.

Any help appreciated 👍

There were casting numbers which can point to the engines age, as I recall, `691` blocks were the earlier MK2 Cortina type , the later `711` block is later MK3 or Escort on, thicker casting I understand, think it was on the r/h side of the block. Can`t pin the dates down too accurately without doing a search.

Thanks for the reply. The year was the first 2 numbers on the block. 691 being 1969 and 711m being 1971 for example.

Mines a 711m hence I know the car it came from was a 70s.

IIRC 681 blocks have a rope rear main seal,anything after has a lip rubber one,711 blocks have more material between 2 and 3 cylinders,am sure I will be corrected if my memory fails me.

Yes, correct, so better for over-boring.

No, not over-boring, it's really interesting.

Are you sure that it's UE and not UB ?

The engine number does usually marry up with the latter part of the chassis number of the car it was fitted to and as such identifies the year/month of build and the specific ID number. What it doesn't do is tell you what model/variant it was fitted in (Capri/Cortina/Escort etc).

From the build dates though, U dates it as 1978 and if it's UB that would put it at September. UE doesn't seem to be a code that was used !!

It could be UB, OB, UE, UB ect it's fairly worn.

You raise a fair point about it only being the build date part of the VIN. I guess tracing the vehicle it came from would be impossible then?

As far as I'm aware no way of identifying exactly what it was previously fitted to, could have been anything in the range with a crossflow engine.

I don't believe that Ford used O or Q as a year code so won't be that. You're probably right with U given that fits for '78

Month codes for '78 were
UL,UY, US, UT, UJ, UU, UM, UP, UB, UR, UA, UG for Jan-Dec

OB was never used, nor was UE in 1978.
UB for Sept '78 most likely as already said.

Pretty much, yes.
