And do you want to run those gears inside your oil pump, of which the life of your engine depends? What material are they made from? How long will they last? Do you want to find out?

 

I said the same thing and it's quit the trick to install them. But....you have to admit this guy is really passionate about these engines !

 

This is one of those "playing with fire" ideas. Much more testing needs to be done. There are lots of unknowns. His gears flow more oil, what is the possibility at 5k rpm the pump will suck the sump dry? What happens when the engine is a quart low on oil? All for a noise, that every m113k makes, and only at idle.

 

I came to the conclusion that it had to be the front scavenge as well but you would think that if it is full of oil from drain back with engine off that it should be quiet on start up than possibly suck the front pan dry and make noise when running. Mine is there all the time and when it's REAL hot after a beating gets very quiet. And again oil type makes a huge difference.

 

I like the fact that the guys is trying to improve on an old platform. He doesn’t seem to be afraid of trying new things and figuring out problems or issues.

I do agree though, it would be nice to see what’s going to happen to an engine after 50k miles or so.

 

I'd be more worried about running the rear sump dry than the front. Nice design though. They do look very familiar from my days with dry sump pumps. The aluminum should be fine as long as there is a fine enough filter on the front pickup and the press fit tolerance is tight enough. He said that he took a torch to it until it started to melt and it still was tight on the shaft. The tell will be long term for sure.

 

the dude has genius level intellect, no question. but the oil pumps used in the 113k(in the 211/219) chassis are off the older diesel motors and will last forever. personally the noise to me is part of the cars character and doesn't bother me.

 

I don't think the pump is going to run a 9 qt sump dry with the slight increase in flow. I also don't think wear is an issue as the gears don't touch each other. BUT when you start modifying stuff other things happen. I think this guy knows what he's doing I just don't know if a little oil pump noise is worth the work.

 

I don't think it's worth doing just for the noise. But if I'm in there anyways I'd consider it just like I would the o-ring. If I don't feel like installing the gears myself I'd just have it done locally or send it to him to do. I'm sure he'd do it for a fee.

 

Gears are 200.00 US and 120.00 to install by him.
Interesting concept though for sure !!

 

The sump in question is run dry all of the time. The gears only affect the forward of the two sumps, so that part is not an issue. If you watch the whole video, he does a decent job of explaining it. That said, there are still a lot of unknowns and installation issues that would need addressed before I would personally consider taking the plunge.

Also, I did the o-ring replacement over the past two days. It's a ***** of a job, but made a drastic difference in the amount of pump noise on my car. I got some before and after video I will put together later, but it's really night and day. Can't really even hear it from inside the car anymore except the normal startup whine.

Edit: Here is the above mentioned before and after video
