Oil psi

[dieseldave]

Is 45 psi oil pressure at 2100rpm ok ?

 

[Tulecreeper]

Yes

 

[dieseldave]

Yes

Thank you

 

[Tulecreeper]

Thank you

It's going to vary between 40 and 50.

I (at 28k miles) rarely see less than 50 fully warmed at 1500-2000 RPM, but 45 does not sound alarming, especially considering that the sensors in our trucks are unlikely to be be scientific grade accuracy...

I had a 1985 Chevy Astro (4.3 V6 - literally 3/4 of an SBC) and 40 was normal at highway operating temps.

Did that Astro van have 17" / 18" or 20" tires on it,lol. As somebody so eloquently pointed out to me a few days ago,this is the 5th Gen section,they don't put GM's little 4.3 V6 in 5th Gens,in fact i can't every remember running into a 4th or 5th Gen Ram with a GM 4.3 in it. So why are we talking about a GM mini vans oil pressure in the 5th Gen section.A GM V6's oil pressure has absolutely no revelance to a 5.7 equipped 5th Gens oil pressure

Same here. Even in summertime temperatures.

what is it at idle? Mine can still drop below 40, even with biotech, increased idle speed, good 5w-30 oil, and the big RP filter. I don't ever let it idle long.

The real question is, would a Ram with a 4.3 transplant still make ticking noises?
