Just got my truck up and running finally and was having some issues with water leaks etc. but got them fixed thanks to you guys on forum. I am still have one problem and need some input. I have a 54 truck with the 239 ohv v8 and I have a pretty good size oil leak after a run the truck for a few minutes. It is leaking out of the crankcase canister out of the tube on the left side of motor. I was wandering what could cause and is there a fix.

 

Are you talking about the road draft tube? Maybe overfilled the oil. check the fluid level. Also make sure you have the right dipstick.

 

What is the overall condition of the engine? Have you done a compression test?
Worn rings can cause excessive blow by.
