My rv-6a with an o320 has about 830hrs since built in 2005. The spinner sits about 1/2" low compared to the cowling. The gap at top and bottom are equal.
My question is, when the motor mounts get old and the engine "sags" does it normally drop straight down resulting in a mismatch of the spinner/cowl but still have the same distance at top and bottom, or do they normally just drop the front of the engine causing a smaller gap at the bottom of the spinner vs the top?
