oil pressure woes

[snowman89]

Wats my oil pressure suppose to be on a 7.3 idi at idle . Hot and cold

 

[hesutton]

Cold idle I see 50 psi.

Hot idle I see 25-30 psi.

my "worn out motor" sees 40-50 cold, 15 at idle warm.

211000 miles on it. lol

I ran the Bronco with 6 to 10 PSI hot at idle and 30 to 40 at highway speeds for years.

 

[snowman89]

Well mine shows 15psi hot and 40psi cold. Is it safe psi _

 

[Dieselcrawler]

yep. ur still good.

snow,,its not the pressure,,so much as the VOLUMNE that the idi oil pump puts out----

Mine holds like 8 idling, and 20 going down the road

mine just says o driving down the road and o driving

Mine is also something like that, a little bit under 25 when hot and cruising, and the needle barely bothering to move when idling.

Cold idle -> 48 - 50 PSI

Warm idle -> 18 - 20 PSI

Warm going down road at 65 MPH -> 45ish PSI

This is also on the engine that has seen 4500 rpm alot!

Where you are reading pressure varies. I've taken pressure from the stock sender location, and it'll be around 10 psi lower than when taken from the spot by the oil filter housing. I see 50-60 cold, and around 30 warm in mine generally, at idle.

I really wish gauge manufacturers gave an uncertainty. A good gauge might be +/- 2-3 psi, but cheaper ones are probably more like +/- 10 or even 20 psi.

i run a cheap autozone sunpro mech oil pressure gauge and my 6.9 shows 45- 50 psi cold and 20-25 warm and goes up from there when rev'ed
