G'Day All,
Anyone come across a valve cover for the 4 cylinder engines produced by Hayes Ionia ?
The attached tag reads as follows:

Hi Ray,
Hope You and Yours are having a Good Holiday Weekend !
The inside looks pretty much like any other one that I have seen. I have other valve covers of the same basic type and i'm not cognizant of what would make one "correct" for any particular year. I have a 25 sedan and have the twin valve covers. This cover was on a 24 Chev engine and tranny that I acquired. I had another valve cover kicking around that had a metal tag from "EATON'S" which you may or may not know was a century old department and mail order company in Canada until they folded around 1990'sish.
This HAYES cover is not in great shape and has actually rusted through in a couple spots on one side. I was just curious about this one.
Thanks for the response and take care..............Joe...........

If my memory is correct, the 4 cylinder engines before 1925 did not have valve covers. Since the cover came off a 1924 engine, perhaps the Hayes valve cover was an early after market accessory to save the driver the nuisance value of having to oil the rockers individually at regular intervals?

Thanks for the responses.
It would be interesting to know exactly when the first after market ones were produced. As Franco eluded to, I wonder how many would have ended up on pre 1925 models, and I'm not sure what stud holes would have been available in the early heads to properly mount them.

All that is needed to install valve covers on the earlier 4 cylinders is to swap out two rocker arm hold down bolts with two double threaded studs and a washer and nut.

Joe, let me make a correction to my statement so I don't mislead anyone. The double threaded stud will have a hex nut in the middle instead on being just a round unthreaded shaft in the middle.
