Early MGA Valve Cover Oil Filler Cap

Dear MGA Owners,

In the early MGA 1500 Owners Handbook AKD598, the illustration showing the valve cover in the maintenance section, shows a painted/printed oil filler cap, not anything like the common pressed steel one with RAISED LETTERS fitted to most MGA models (except Twin Cams.)


I recently came across one that came as a spare with my 1957 MGA.
Does anyone know when they stopped fitting these?

Cecelia,

I have seen a valve cover cap like that only once.

As far as when the factory might have gone to the later Wingard style valve cover cap: In March of 1957, at car #18418, the factory (per Clausager) changed the valve cover to improve sealing. Maybe they changed the cap at the same time? Don

Dear MGA Owners,

I had only ever seen one other on an early 1955/56 MGA, took a picture of it, and never have seen another one, until this one. Anyone else have any ideas?

I had one fitted to a rocker cover on an MGA 1600 engine that came with my car an MGA MK11, it was the same as the oil cap fitted to my grandfathers Austin A30 so it could have been a generic part fitted at the time or a replacement part.

Dear All,

Upon further research, I just looked in the first edition MGA 1500 Service Parts List (the green cover one) to check the part number for this cap. It is 8G612 the SAME part number as the later all steel 'Wingard' style.

So, who knows!

I'm not sure I would take an illustration in the Owners Handbook ( or Operation Manual, as my AKD698, First Edition, calls itself ) as a definitive indication of any such small details etc.

The Handbook might have been in preparation before series production began, and/or used drawings already existing in other manuals with only minimal changes for the MGA manual..

I suppose the only way to know is from someone who was there, or a car with a completely known history; not many of those after 60 odd years.

Cecelia, Here is a picture of mine when I got the car. Kind of looks the same without the print. I have since replaced it with the newer style. March 9th 1956 build.

Dear Ron,

Yes that's the same one (but without the printing).
So, we know at least the month & year it was still fitted to. The one I have came with my car, but not installed on it.

Cecelia, That oil filler cap is exactly like the Original cap on my 1956 ZA Magnette with the Original 1500 cc engine in it. The engine is unmolested, so the cap would be original as well. The printing has rubbed off to quite an extent, but still readable in places. Their is no question that it is the same.

BTW that Ice Blue tonneau I got from you still looks great on the MGA.

Picture of the Oil cap on The ZA Magnette, and the engine number that is correct to the car. The Magnette Serial # is 15415.
