Hey everyone, hope alls well.
I recently performed a compression test on my left bank of cylinders, and found 1, 2, and 4 sitting at 95 psi while 3 was at 75. I am blowing smoke when accelerating so I think it's time for a rebuild soon. In the mean time, is there any fix for the low compression on cylinders 1, 2, and 4?

Let's see fixes for low compression:
Mechanic in a can ( was a thing in The 70's, some graphite balls and liquid went into cylinders )
Down and dirty cylinder hone and file to fit rings.
And my favorite, a junkyard exploder motor.

Shoot, may be time to hit the junkyard. I love this little 289, but I really don't want to drop the money and the time on a rebuild because it's my daily driver. Sorry but I'm not comfortable putting gasket fixers/sealants in my engine as I feel it'd just gum stuff up in that old of an engine.
