I just started the 89  van today.     This time there was no red light from the oil pressure indicator.   I cranked the engine anyway and ran it at idle for a little while.   Oil started leaking from the oil pressure switch between the pushrod tubes so I have confirmation that that switch is bad.    I will replace both the switches and do some other jobs before I run this engine any more.     Steve
