Title: Oil Pressure/Check oil on 1919 Chevrolet 4 Cylinder
Post by: Chevy490 on February 14, 2016, 07:54:28 PM: I just got a 1919 Chevrolet model 490 with the original engine. The engine runs good. It has no dip stick. (and apparently never had one) There are 2 drain spigots on the pan, one higher than the other. I am guessing the lower one is used to drain the oil. The top one is used to check and see if any oil runs out of it?
(Fill it up until oil just barely runs out of the top spigot to check proper oil level?)
The oil pressure gauge only shows about 2 lbs pressure. I don't have the service manual yet but I am guessing this engine runs on pretty low oil pressure at idle. Thanks for any input

This engine never had a valve cover, the oil can is to lube the valve train every time the car is used!

Looks like approx 4qts, bottom drain and top petcock to check fill level. Another fella on there was talking about waiting for the pressure to reach 2psi before driving.

You can check them out @ Vintage Chevrolet Club of America(VCCA) at the link below under "other forums".

Some of those guys might know about the earlier engines. I'd like to see pictures of your car. I'm working on a '26 roadster with a newer engine and I have a couple of '28 engines. A friend in rebuilding a '25 dirt track car. I also have a 1919 Essex 4 Cylinder I'd like to put in something racy.

Post by: themoose on February 14, 2016, 09:58:39 PM: Welcome aboard...Here's a link to a pretty interesting discussion about the oiling system on VCCA chat where one of the guys mentions 2 lbs of pressure so it would seem that's what they run.

Post by: sixball on February 15, 2016, 10:55:00 PM: That is very nice. I bet it is a lot of fun. Even the later Chevy 4s up to '28 didn't have a valve cover like we expect. It was a dust cover and the bottom did not seal. There was a felt pad that was squirted with oil and oil from it oiled the rockers. You find a lot of worn out top end stuff.
