    Push rods are even more often changed. This lists only 6 cyl around this time: Type Y: 11 1/4----------D 6 Cyl. except 54, 55 12 27/32------C 54, 55, D 54 55 10 11/16------E 6 Cyl. Type X 12 21/32------H-K-1921 6 Cyl. 12 29/32------1922 6 Cyl. 14 19/32------1923 6 Cyl. So the push rod I gave you is too short for your engine.

    Wow. They changed the camshaft much more often. Here are the different camshafts for 6 cyl: B-54, B-55, C-54, C-55, D-54, D-55 E 6 Cyl. H, K 6 Cyl. D 6 Cyl. except 54, 55 1921-1922 6 Cyl. 1923 6 Cyl. 1924 6 Cyl., 1925-1926 Master, 1927 Ser 120-128 1925-1926 Standard, 1927 Ser 115 So basically my springs are unique and I can only use that one

    I notice that E 6 Cyl has unique springs, that were replaced by a spring for H, K up to 1923, even though the valves and cages were not changed. Why did they change the spring but not the valves and cages? Maybe they improved the spring for the H series and I can use them for the 3 springs in my car that are not original. Let me look and see if they changed the push rods or rocker arms between E and H, or more importantly, the cam shaft. A faster cam would require a stronger spring especially with roller lifters.

So your spring goes all the way back to model F

    I did not know the model 10 was the first 4-cyl Buick with valve in head. The older Buicks had T-head or were 2 cyl. So, I guess the basic design of Buick engines up to the 1920's all goes back to the model 10: http://www.carnut.com/specs/gen/buick20.html .

    Looks like your valve goes all the way back to a Buick model 10. Here is a picture of a model 10 engine from 1909, I'm amazed at the similarity:

    The exhaust valve stems are .368 to .369 thick on my 1918 242 engine Intake are .383 but you don't need that info

    Modern Fluids for Early 20's Buick's??

    This is right on. Steering gears would use grease, but it relies on gravity to keep it from moving up the steering column and getting lost up there, it has to slowly come down.

    7.) Blinker fluid Not used until 1939. None needed in 1922 models.

    I used my more accurate caliper and found that the exhaust valve cages for the 242 engine are 1.685 inches diameter. I also have a couple extra bronze rings as Terry sent me 8 and I only needed 6. Let me know if you can use the cages. They are in the spare engine which you saw, it's also a 242 engine from 1918. Obviously you can't use the intake cages. The springs, according to Gary, are too rusty to use. It seems a previous owner cleaned off the black oxide and spray painted the springs red. An idiotic move. Black oxide prevents rust, red paint flakes off and rust happens. You can use your old springs I think.

    Besides, now my car goes 120.

    I saved the dial from the 1940 speedometer in case I wanted everything to be "correct" and change the face of the 1941-47 speedometer, but I decided to leave it alone and leave it together, taking it apart is just asking for trouble. These things are so finicky, it might start squeeking or something. Right now it works fine and that's good enough for me.

    On my 242 engine from '18 the intake cages are 2.065 inches and the exhaust are 1.685, don't know if that helps if they aren't coming out. My buffum tool is broken, all I can say is, I got my cages out by soaking them in 50/50 mix of acetone and brake fluid.

    Valve springs for E 6 cylinder engine (1918)

    It looks like you are quoting something I wrote in Wikipedia. Very interesting having your own words argued back at you. Davis never made a car and never produced an engine, he just solved the problem of how to cool the head in an internal combustion engine with OHV --on paper--. Rocker arms and push rods were around for 100 years in steam engines but when they tried to use the concept in internal combustion engines there was no way to cool the head. Ford made a car that always overheated, check the history. He got his design out of a magazine written by a guy who never made an engine either. Nobody made a successful OHV engine that didn't overheat, until Marr.
