Subaru EH72 FI Rocker Arm Failure
Just had one fail on my Engine. 160 hours total time. Subaru said that the rocker arms are designed to fail when the valve sticks. The say the valve sticks because of one of two reasons.
1. Old fuel (not my problem, never sat more that three weeks without starting and I use Seafoam in the fuel)
2. Over revving. Cant do it on this engine because the EFI unit limits the revs. Tack has never been above 3980 RPM
Anybody else have this problem with this engine?
