Good news! I have checked my compression and each cylinder looks good! So happy to rule out a head gasket issue. I think my next step is going to be inspecting the heat exchanger for pin holes.

Just curious, what was your compression? TY

Again, “does she have the 2” or 3” Hx?”


Another method to ck the Hx, is to remove the Hx end caps; pressurize the closed system at the pressure cap (loaner from auto parts,) and look for coolant dripping out from one of the Hx internal tubes.


Again, at that age if it hasn’t already it’s overdue to fail. Replace it.
