Hi all,
I was just reading one of Lockwood's "Power On" aricles titled Keeping
Cool. The paragraph "Signs of an Overheated Engine" gives some telltale
signs, one which is " The cylinder head bolts suddenly become loose."
Garry, has she gotten too hot maybe? Do you use waterbased antifreeze or
Evans NPG+?

I would like to remind all Rotax drivers to periodically check the
torque on the head bolts of their engines. This past weekend I sprang
a major in-flight oil leak necessitating an emergency landing. Oil
was gushing from between the head and the cylinder. Upon landing I
checked the head bolts on that cylinder and found two of the four to
be less than finger loose. After tightening them up, I checked all
the other cylinders too, and found 3 of the remaining 12 bolts to be
slightly loose. All should be torqued to 200 inch pounds. For
reference purposes, my 914 engine is 7 year old with almost 500 hours
on it.........and I never checked the head bolt torque before.
