1919 Chevrolet Engine Run

[kirkconway]

i wonder why chevrolet would let the rocker arm's be open and get dirty?

whereas ford and other's had them enclosed and away from dirt.

Right before watching this video I watched one with a helicopter. Strangely, it's got exactly the same sound.

Hello, I have the same engine in a doodlebug I just bought. I can get the firing order by wtching your video, but I need to know where the positive/negative battery cables go. I also need to know how the ingition/charging system is wired to the switch. Any help would be greatly apperciated!! You can contact me at gettenmymindright@yahoo.com Thanks Jeff

what's the RPM at idle? seems very low

[iggy151]

Eargasm.

[pismo10]

So that's an overhead valve engine? in 1919?

[organfandan]

@pismo10

Yes, this design based on the Mason engine of the Little and Whiting automobiles and used in Chevrolet since the early 'teens.

I wonder if anyone has ever made a retrofit valve cover for these things.

[picapop12345]

fasinating. I heard they were called a 490 because they costed $490.00 to buy/

[vettelover2009]

that is so cool...do you use a non-detergent oil, conventional oil, or synthetic to oil the valve train.

[organfandan]

@vettelover2009

I have a booklet, "Instructions for the Operation and care of Chevrolet Motor Cars Four Ninety and Superior Models", it specifies light cylinder oil to lubricate the rocker arms and pushrod felts. I use regular 30 weight motor oil. Dan

[KapteinOpel]

@organfandan Ehm... The "W" stands for "winter" and designates the viscosity of the oil in cold condition.. SAE30 would be a single grade motor oil.

I really like the exposed rocker arms! take a look as some of the 20's Buicks!

[fourfortyroadrunner]

My Dad and uncle, long before I came along, teamed up with a '25 Chev, homemade wood pulley on one rear wheel, sawed wood around town. I remember the "junker" when I was about 8. No valve cover, I thought then it was missing, maybe not. Never ran when I was alive, Dad sold it for scrap soon. Us kids "drove" a lot of miles in that old car!!

[digitalrailroader]

and to think, Nowadays, Chevrolet is now making engines that make upwards of 600 HP! its awe inspiring to see Chevrolet come from such humble beginnings!

[chopperdavez]

Dan, absolutely brilliant...thank you for this video. I am currently restoring a 1919 also

[sbd650]

5*****!

[atvheads]

I guess that its gonna bee quite messy in

the enginecompartment after a while, with all the oil splashing around.

Or?

Nice engine by the way.

[organfandan]

Thanks. Top engine parts are hand oiled only, so not too messy, although in the old days I imagine dust from the dirt roads would collect on everything!

[douro20]

Isn't this actually a Buick engine?

[organfandan]

No, but they both did use open valve gear.

[BlakeMason2]

Sweet restoration.

[HERodriguezJr]

Beautiful man! :)

[salemcripple]

wow. it's not a flat head. I thought for sure it being a 1919 it would be.

[bobmillerbob]

That's a very nice sweet motor.

[Electra72]

so im guessing you have to oil it before every run...or does a good shot last for a while?

[organfandan]

Original lubrication chart specifies oil on rockers every 250 miles. I usually do it more often.

[chuckkottke]

Uncle Julius's 1909 Packard had some type of device to lift the oil onto the rockers; I wonder if there's a simple add-on that would do it? - I love to see all the moving parts on these engines - thanks for posting this!!

[nomorepigshere]

That looks like a Chevy '490' engine, 490's had no rocker covers only 'Royal Mail' and 'Baby Grand' had rocker covers/with holes to oil the rocker arms.

I had a 1917 'Royal Mail' with the 224 CI four cylinder, it's stroke is one and a qurter inch longer than the 490's 3 13/16 X 4 inch bore/stroke engine.

[rdillon7872]

No rocker cover. Did they make that motor without a rocker cover?

[organfandan]

Yes! No oil pumped up there, so no cover needed to contain flow. Rockers oiled by hand using oil can stored in clip on firewall (you can just see it opposite horn).
