I was doing some control on my OS 50 Hyper, and I was turning the motor by hand near my ear. I listened a "pshit" coming from the glow plug at the compression. Very quiet pshit...
What can I do? Is it a problem? My engine has 17 flights, like new...

Make sure that the brass washer is on the glow plug. If it is and the glow plug is tightly secured, have you tried another glow plug? You may also need to tighten down the head bolts; they are somewhat prone to working loose.

Yes there's the brass washer. I will try to tighten the head. But the strangiest, is it's only making a noise only in reverse direction.:arggg:. And I tried with a new plug with no success.
