Hi, Sounds to me like the oil ring spreader or spreaders were incorrectly installed. They must butt together, sometimes when putting the piston back into the cylinder the spreader slips and overlaps.If thats the case, the oil ring or rings are not being pushed out against the cylinder walls. Thats one scenario. How about the heads? Were they reconditioned too? Email me with all the details on what was done to your 327. I will try to help out with the info you provide.
