Blow by from oil fill tube

[Seth Swoboda]

I ran a 221 V8 that had low compression once. It smoked out of the breather cap all the time. When going down the highway, you could smell the crankcase fumes. I solved it with a rebuilt engine though. However, you are trying to avoid that.

Maybe do a compression check also. That will let you know the condition of the rings. Sometimes you can find good V8's that are being removed for SBC's for sale at reasonable prices.

How often are you adding oil to the engine?
