Hi list,

About 2500 miles after I installed a new clutch and
replaced most cooling hoses and O-rings, a small leak
developed at the O-ring between the cylinder head and the
thermostat housing. I noticed the O-ring was fairly thin, are
there thicker replacement rings? Any recommended sealing
compound I could add during assembly? I cleaned the Al head
and O-ring groove carefully, but the plastic part showed some
degradation. What is the O-ring material - we purchase many
different kinds at work (Viton, Silicone, EPDM) and might get
one if I knew size and material.

Many thanks,
Wolfgang
