Hi all, =

Way behind on email since power has been off for several days= and could be off another week or so.

But on oil temps, I NEVE= R run it over 210 and it runs 180 - 190 on hot days at low altitude = (hot muggy air) at cruise. If you want long engine life I don't th= ink there is any other choice.

Will not be a= ble to read all back messages but in case no one has mentioned this, evap= orator cores see 120 - 180 psi when the car is PARKED (not running). = ; The pressure goes down to around 32 psi when the compressor is ru= nning.
