I agree that 220-225 deg.F isn't the normal operating temp. for these engines since the standard equipment thermostat is 195, but it's not unusual to have coolant temps increase to 220-225 during prolonged idling under hot conditions without damage to the engine. Normal operating temps are 190 to 200 with oil temps generally about 10-15 deg. cooler (at least that's the readings I see on my L83). Since engine life is a function of wear which depends largely on oil viscosity, oil temps. are the most critical measure when gaging engine longevity. Most modern multi-viscosity motor oils can tolerate these temperature excursions without seriously impairing their performance or the service life of the engine. Maybe we should start a new thread on oil temps and engine wear 
.
(BTW, it's 90F with a heat index near 100F here today in central NJ).

Pretty much 98-100(real temp)every day here ! Well, hot engine --- hot oil I don't want an engine that the oil has to tolerate the engine temp. Everything I'm hearing is "can stand the temps." or "can tolerate the temps"' and it's normal to run just south of boiling ! None of that sounds normal to me ?
I've always thought Vettes should have an oil temp. gauge anyway, actually, all cars ! Drain plug for the trans. too ! But thats another story. Well I guess thats my 32 cents,
Later folks
The guy with the ping should open a new thread, should be an easy fix, not that many things it could be ?
