Identify this WW2 Luftwaffe engine valve

[tracer.smart]

When I was a kid, my dad acquired a bank of engine cylinders from a wreck of a WW2 Luftwaffe bomber from the lifeboat coxswain in Whitby.
The coxswain I believe collected crash relics and trawler crews who brought them up accidentally in their nets knew this and would pass them on to him to show goodwill.

There are plenty of a German aircraft wrecks around the north east coast - the Luftwaffe would often attack shipping and the RAF became pretty good at intercepting them.

The engine block my dad acquired was an incomplete bank, only five cylinders out of the six. It had the manufacturer name Jumo cast in to the block with some other numbers.

Question is, can anyone identify the engine model and therefore what aircraft it likely came from from the valve? Picture below, the valve in question is on the left. For comparison next to it on the right side is another valve which I found inside a single engine cylinder at a Junkers 88 wreck site on a beach, so it’s definitely not from this type.

It might still be from a Jumo. There were quite a few variations in the Jumo 210 family and they were used on a variety of bombers - He111, Do 17, Ju88 and its variants.

He already knows its a Jumo engine.

I just found this image amongst pics of the Dornier 17 restoration. This looks the same as the valve I found at the Ju88 wreck site, which I guess means the Dornier had the same Jumo engines.

Does this rule out the Do17 and Ju88... meaning the valve on the left is from a Heinkel 111?

I suspect he meant ju88. There are a range of jumo engine families, several of which found their way into the ju88 family of aircraft.

I've just been reading up on Ju88s (I'm thinking of building a model Ju88 sometime). Most had versions of the Jumo engine but some had BMW air cooled radials.

Could be from a He111 or Ju88 which both used the Junkers Jumo 211. Unlikely; to be from a Do17 as they mainly used Bramo engines.

The Jumo used solid steel intake valves and sodium filled exhaust valves, so they could be from the same type of engine despite looking different.

You could try contacting the Wings Museum in Sussex, and ask them, as some years ago, they restored a Jumo 211 for the Norwegian Airforce Museum Ju-88.

Im pretty sure they're both exhaust valves, and its the valve guides that are obviously different, from the image. Shouldn't be a difficult task to identify for someone at a museum that has one or other of the engines.

You could always try the Luftwaffe section of 12 O’Clock high, friendly bunch and very knowledgable if you ask nicely

Bloody love Junkers 88s....genuinely one of the most amazing multirole aircraft of the war and almost on a par in the versatility stakes with the much later Mosquito. I’m biased though...my great-uncle flew and died in one.

Such a shame that there's never been any serious attempt to re-create an airworthy in the past few decades. There's been a fair few remains dragged from the northern tundra and a few fresh water lakes, on top of which, with the Flugwerke 190 new-builds using the Ash radials, a viable almost new build late model Ju-88G which used the BMW801 radials should have been possible in the same way using the Ash's in the same way......

Crikey look at the size of that valve, 3 house bricks tall!

It is quite amazing the progress made when WW1 aircraft engines maybe kicked out 100HP then WW2 aircraft engines did maybe 20 times that.

The Dornier Do.17Z doesn't use the Jumo V12, they were fitted with a pair of Bramo Fafnir 323 radial engines.
