1988 corvette Oil pressure

[Harry Nye]

Hello folks, can anyone tell me what the oil pressure should be in their 1988 corvette when hot at idle. I have a friend that has a 40K mile car and is the original owner and when we took his car out for a ride in about a 95 degree day, the pressure when hot went down to about 17-lbs at a stop. At cruising speed about 45 to 55 the pressure was about 45 lbs. Does this sound normal for the 5.7 tunedport motor. Thanks

It sounds about right to me. Keep in mind that even on an 88, the oil pressure gauges are not 100% accurate.

Idle pressure as low as 10# was still considered normal by Chevrolet when new on my mid-late 80's C-4s
