I have a valve, but didn't want to put it in till I design the rest of = the

What say ye?

Yesterday morning, OAT about 70, water temp about 170 when I took the

The temp seemed pretty stable around 200, but it did climb to 210 one time<= br> for a short period for no reason that I could figure then came back down. EGT I thought was pretty high, around 1600. =A0Mixture about two bars above=
