Sorta good news?

Yes, finally an English made engine with timing marks! They line up within a link, so can't get any closer.
Got all the valves apart, none were in the right location, nice for each to be numbered tho, more best of British ideas! Funny that one exhaust had only one spring, the other 3 had inner and outer springs. Tommorrow I'm going to see if ones from a continental will fit.
And the exhaust ports were rather rusty, a tan rust? Ran too lean or ???? The ends of the exhaust stems seem worn, I bet not having those rotors was something to do with it.

Stem wear due to missing lash caps maybe? Not sure if the engine had them originally. What do I know, my 23C has Deutz valves in the head!

Yes, the stem rotors mentioned they were built with, but now 'unavailable'... so now thanks to John UK, the cross reference is now 'British Sports Car Spares'.... are there any British sports car parts left in the US? I suppose that's what craigslist and Sam's suitcase allowance is for is for....

Tooonee go look thru that post of mine called interesting items, I think the stem caps were in there maybe the rotors.Dont remember seeing any on mine.

Not all Standards had the exhaust valve rotators. The "EVR" after the serial number denotes exhaust valve rotators.

My 1953 Standard engine did not have exhaust valve rotors. I'm guessing your 1953 TEA20 also did not have exhaust valve rotors.

Seems you're the one to ask this one John... how the heck many valve springs we suppose to have here? I am looking at 7.... do I have one to few? Or 3 too many? I get differing answers from different books and sites.
I will look for those intials, but the tops of the stems sure look pounded, maybe just years of use? Fawcett's hasn't got back to me yet- any old Fergie bone yards in eastern Ontario???

Tony this is from my parts book which is dated 1957. It shows a single spring and no lash caps. It does show another spring that was used with roto caps but that's it. Mushroomed valve tips doesn't suprise me if it's the original valves. I've taken apart many engines from the 1960's and they still were using soft tipped valves then.

Tony: Mine only had one spring per valve. Broke one exhaust spring which is why I had to replace it. Got spring through MF dealer at Springbrook, Ont. Did not find valve rotator listed in parts book but did find it in the engine. With John(UK) assistance discovered that some engines were equipped with them mainly for testing for the upcoming (at the time) 35 engine. The serial number suffix indicates if they were installed. I had no knowledge of them until I went to repair mine and found the small springs and balls on top of the head. Sure glad they did not fall down the push rod side. Got all springs and balls and put it back together. Took photos and measurements of the pieces and sent to John(UK). That's about all I know about them.

In my parts book the roto cap and spring is not illustrated but it is in the parts numbers. It starts at #37.
181851M91 1 Rotocap Kit, Exhaust Valve
181849M1 4 Spring, Valve
181850M91 4 Rotocap Assembly
825483M91 1 (C) Decarbonizing Set (85MM)
(C) - Order (1) 825003M1, (2) 825194M2,
(1) 825836M1 And (1) 829029M1.
Personally I wouldn't mess with the rotocaps.
