Question
1950 Chevrolet Pickup
I just purchased a 1950 Chevrolet 3100 pickup truck with a 235 inline 6. The dipstick does not appear to be original to the truck and I am changing the oil. The old oil read about two quarts high on the stick, but the stick appears to be too long. I will replace the oil with the specified amount and scribe the stick until I can get the proper dip stick.
Can you tell me the crankcase oil capacity as i have to manual as of yet.
Thank you very much,
Ed
