Blow by and ring replacement

[dbrahms]

I have a ton of blow by from my 360 puffing out the dipstick tube. motor has approx 1500 hours on it but seems to run ok.

question is, can i replace the piston rings without removing the crank or pulling the motor?

Unfortunately, no. While, technically, you can remove a piston without pulling the crank, it’s still a significant tear-down that requires pulling the engine, removing a connecting rod, cylinder head, etc.

Yeah, while you're at it you might as well have the crank cleaned up at a shop, and replace the bearings, oil pump and seals
