Just wondering where the engine code is stamped on the focus rs mk1 engine, im reading online and after searching here its either on left or right side of cylinder head, looking at the images some have it stamped some dont? should i be worried if its not stamped?

cheers guys!

 

Isn’t it on the flange near the crank sensor ?

Should be the engine code then the engine number.

So somthing like Hdma 4b1234

 

on the ones ive seen stamped its just above thermostat housing - im guessing its been rebuilt at some stage as head gasket looks new...

yes that engine code format is correct...ill have a closer look...

 

Like Wasa says it's on a flat area close to where the bell housing attaches just above the crank sensor.

 

Yep def no stamp...someones just scraped a 'H' in to the cylinder head

Head gasket looks new, im guessing, well praying, it was rebuilt and stamp was lost during clean OR its an uprated cylinder head .(im dreaming now ) ...i hope n pray it isn't fake..., block looks, fine it has RS plugs, and the bottom end has all the correct fixings, oil return etc....im sure there is a simple explanation

 

Late engines where laser etched in a dot matrix style. They fade / rust easily. They can some times be seen with a camera

New crate engines never had a number. The dealer was meant to stamp the number in on exchange but time is money and the punter is non the wiser anyway.

Never seen an Rs crate motor.

Factory recon, as above.

Only other reason would be dubious providence.

If it has the Rs water pump, larger Rs modine oil cooler, Rs oil seperator heat shield it’s likley to be an Rs engine. Yes you can bolt these to a Zetec but they don’t come up for sale often. Only other way would be to tare the engine down and check the important bits.
