I have a 1978 Ford, E-150,v6 ; mileage 177000
Has been well taken care, original paint,almost in mint.
That I got from the original owner, 7 months ago.
I toke the van on a roadtrip(800 miles),got to my destination,everything was fine.Gave an oil change (10w40) before coming home. About 550 miles in to the trip home, as I was entering the mtns.(going up). The engine gauge started going up and the oil presure gauge went up also(that day was really hot).So, I stop for 45 minutes for a brake. Started the van up again and drive a mile till both gauge where in the dangerous level. Stayed over-night for things to cool off, checked all fuilds in the morning, all were full and after starting, gauges were good. Finished the trip home with a few extra stops when the gauges would go past the norm.
I have driven it a little here, and the engine and oil gauges will go up for a few minutes and then go back to the normal spot.
I found out that the original owner switched from 10w40 to 15-40 five year ago(15,000 miles ago).
Could this just be because of a different oil, and why would the oil presure go up if the engine gets hot. Shouldn't the oil presure go down when the engine gets hot.
2 rows in the radiator.
vacuum is at 18in. at idle.
Thank you for your time.
