Car Forum / Dodge / Dodge Trucks / March 2007Std Oil Pump vs High Volume vs High Volume/High Pressure
I have a Dodge 5.2L (318) and they list 3 oil pumps for it. Of course the standard pump and then a High Volume pump that is recommended for higher mileage engines which says it pumps 20-25% more oil and then they list a high volume/high pressure pump. I was thinking putting a high pressure pump in an older motor (100,000mi) would be asking for oil leaks to develop. I was thinking about the high volume pump, but are restrictor plugs required in the block like chevy small blocks are required or a higher volume oil pan? > I have a Dodge 5.2L (318) and they list 3 oil pumps for it.

One other thing, high volume and high volume high pressure pumps take more power to run. I've seen them eat the cam and drive gear. Al > I have a Dodge 5.2L (318) and they list 3 oil pumps for it.

If you're having trouble maintaining proper oil pressure in an old engine, then a high volume pump is a good idea. The trade off is that they take more power to run. On newer engines, they can eat cam and distributor gears. One of the inherent "problems" with a high volume pump, is that you often need a high volume pan to with it. If it's just a street truck, and you drive it gently, it will probably be OK. If you're replacing the pump to get better pressure in an old engine, it's probably a worth while delaying tactic. Eventually you'll have to rebuild the engine (or sell the truck) High pressure pumps are for racing only.

If it's just a street truck, and you drive it This is all bull pucky. The extra power is minute and maybe if you have a tight engine and it is zero and you have 50 weight oil in and a rev the snot out of it cold you might strip the gear out. In a worn engine a higher flow pump is a very good idea because it floats the bearing a little bit better and cools then a bit more too and helps extend their life. The higher volume allows you to use a lighter grade of oil in a worn engine and still float the bearings properly. The only cooling the bearing receive is from the oil flowing through them and there is heat being made in them from shearing forces and a increase flow will tend to reduce temps in them a little bit too. ----------------- TheSnoMan.com > > If you're having trouble maintaining proper oil > >pressure in an old engine, then a high volume pump is a [quoted text clipped - 18 lines] > ----------------- > TheSnoMan.com You should stick to something you know about, like plowing snow.

Ok Al, please show us exactly where he is wrong.

LOL, I was going to ask you to explain what this meant until I say the thread that you were talking about.

Did I say he was wrong? You didn't say it but you sure implied it and if you don't think so, then your command of the English language is a bit on the weak side. > Or, did I say he should stick to something he knows? Which means exactly what? Since he was correct here, he appears to know this subject or at least this much about it so what exactly is the point of your post?

Even I have to say "Huh" at this one Tbone.

There you go again. Everyone else is wrong, and you're right. Even if you say the same thing with differant words, the other words are "bull pucky", and yours are not. Good thing you're around to set everyone else straight. If we were in a bar, I think I could stand about 90 seconds with you. I'm a very patient man.
