hey all: talked to Hastings ring co. about the massive oil problem. "Read" the rings to them over the phone to what they look like. It sounded to them that the compression rings were spinning in the grooves. Finally got two people to think maybe the grease wouldn't let the rings catch right away and the rings were free to spin. By the time the grease was gone it was too late and the rings continued to spin and ruin them. The 2nd compression rings tapered "edge" that contacts the cylinder wall to scrape oil off lookes to be "rounded" off. Some feel the spinning ring could of ruined the ring(s) by "filing" them down by wearing the wrong way across the cross hatch pattern. Any thoughts on that one? We sent a pistion and rings out of the first rebuild to Hasting's to analyze for us. I'll let you know what they say. We haven't taken the motor apart yet. We're going to wait for their response. The top comp. ring on both sides are polished off with circular "cut" marks around the entire sides surfaces. Compression rings on all 8 cylinders are worn the same. Detonation was the only common thing associated with ring spin. (there are other reasons, but we feel they don't apply)
We don't feel the engine has a detonation problem. Any thoughts on this? Let me know. Thanks
I NEVER PUT ANY THING ON THE CYLINDERS EXCEPT SOMETHING LIKE WD-40.YOU WANT THE RINGS TO (DRAG) SO THEY SEAT.THERE ARE MAKERS OF A PASTE/POWDER THAT YOU PUT IN THE BORES TO FILL THE CROSS HATCH MARKS UP SO THE RINGS WILL SEAT FASTER.YOUR PISTON RINGS HAVE TO SPIN FREELY ON THE PISTONS.WHAT WAS YOUR CYLINDER BORE TAPER?WHAT WAS YOUR RING END GAP?WAS IT THE SAME ON THE TOP AS IT WAS THE BOTTOM RING?WHAT WAS THE FINISH IN THE CYLINDER BORES?DID YOU STAGER THE RINGS?
