From the Brickboard FAQ:
960 Valve and Head Problems.
Sticking Valves. [Summary of tips from Tom Irwin] To avoid the sticking valve problem in the B6304 engine which causes valve and piston collisions and consequent head meltdown, follow carefully this advice for 960 owners from Mr. Barrington of Barrington Engine of LA, rebuilders of many toasted 960 heads:
1. The Abe Crombie Tune-Up is a GOOD thing!
2. Put a fitting behind the AMM for occasional, brief WATER introduction to the Hot engine...while
running Shatters and blows away the carbon build-up.
3. ALWAYS ALWAYS use PURE SYNTHETIC OIL! VERY insistent on that one!
