ok, serious question without any kinda bs behind it.

how did removing that little bracket in the stock pan help increase oil pressure at idle? regardless of oil temp, in a stock pan vs ppe pan at the same oil temp, will the PPE pan supplied truck show a higher oil pressure all else equal? or am i just reading it wrong?



No one is perfect here but Dan has help a ton of people with a whole lot of other parts and issues. Im by no means a PPE nut swinger, most of you all know that but when i need things i cant get else where or they just flat out have the parts to have, Dan helps me out. the crap questions are out of hand. there are better ways to go about it.

Ask a question about a product being sold by a company, get the Hilary Clinton run around with no definite answer. Sign me up 10 and just take my money. :rofl:

Provides answers to questions, being asked by a potential customer, who are unable to comprehend....:hug: PM your cc info and shipping addy... I'll get them sent right out!!!:thumb:

I plan on buying and trying one of these once temperatures stabilize around these parts and will provide oil temp logs from before and after the swap. This will be done with same ambient temps, same drive, load, speeds, etc. to keep the test parameters as even as possible.

Regardless if there is/isn't a marked improvement I will post up my results.

Sounds good to me/us! For your specific testing, I will refund you once we get the pan back, if it doesn't do what we say it does!

Yes! I don't think the bracket being removed is what is giving the gain is PSI. I feel it has to do with the humps and ridges that are partially shrouding the oil pump pickup on the stock pan. PPE's does not have these on the inside, also provides just a little more space between the floor of the pan and pickup. This reduces the inlet restriction (less vacuum in inches) and allows the oil pump to work more efficiently.

thanks Dan, i was wondering if thats what you meant by "unshrouding". :D

Dan, what are you trying to hide from us. Where's the proof this even holds oil.:roflmao:

No kidding!

Jokes on us, can't even pull the pan with that cross member in the way. Guess I'll have to pull the engine for this mod :confused:









*That's sarcasm for all you idiots*

Nothing new to the Duramax world It is now special because dan sells them also.

Yes, I realize that, but it's nice to have competition on products. If only one manufacture makes a product them seem to charge what ever they want for a part, but if they have to compete with other companies it helps keep prices in check.

I don't understand why you guys are bustin Dans balls about this pan!

Dan, go to any decent hydraulics engineering site and read about pumps, suction and discharge and you'll find that you're correct. You'll find the less restriction cavitation around the intake the better the suction and the higher the volume and pressure on the discharge side depending on the size of all related components. Yes we would like to see real world testing but you have seen differences in 5 trucks and from all the hydraulics engineering sites I been on in the past the change you made would make a difference, the additional clearance (1 quart) between the pickup and bottom of the pan and the flat bottom

Lift pumps have the same problem, the intake/pickup inside the tank is smaller than the discharge of the pump, and guys rarely if ever question why the pump burnt up and never look at the beginning of the supply which is anemic at best as is the case of the oil pickup being in a real bad spot...

IIIRC the Duramax pan like the drivers side manifold was "manufactured" for the test mule truck and these "indentations" were incorporated for the mule and never changed for the GMT-800 truck chassis and GM never thought it to be problem for the stock truck and has not been. The manifold indentation "appears" to line up with the GMT400 steering shaft and the oil pan for the cross member.

If it was on my plate to purchase I would be inclined to do so, but my yearly maintenance and small modifications monies are maxxed for the year....:thumb:

PPE offers some of the best products... Looks like I'll be getting one too!!





Fixed it for ya...:roflmao:


You just can't ever say anything positive, every post you make in any thread is always negative. Just keep your comments to yourself.

LOL... are you sure? look at the nice stuff he wrote in this post... :rofl:



I don't read every thread on here, but is this "par for the course" for him? or do I just rub him the wrong way????

Way to use your admin privileges to help boost your product by erasing people stuff and editing. Real mature

Maybe stop being such a douche.... and have a real conversation...


I think I should just start calling you Nancy...as in Negative Nancy... as this seems to be your "calling card" on here.... :baby: :spit:

ive taken many a burnt lift pump apart. 95% of the time, its seals gone bad and filling the motor with diesel. i dont think a bigger suction tube would hurt one bit but its not the main reason you see AD pumps or the few FASS pumps failing...

no its par for the course. 9/10 times he has a disagreement or feels someone else is wrong is damn near all his posts.

That is funny. Everything I brought up is legit but since you have nothing to back up your project you just delete my fax.

Restrictions on the inlet of a gear pump do reduce its output pressure, but won't damage it. In fact, that is how the CP3 regulates fuel pressure: by starving the inlet of fuel. They last hundreds of thousands of miles. So I also doubt that failed lift pumps are due to inlet restrictions, at least if they are gear pump style.

So if the stock pan is effectively restricting the intake, it will lower oil pressure (conversely, this pan could well increase oil pressure). However, I am not sure I believe the restriction on the stock pan is enough to affect oil pressure. I don't doubt that Dan / PPE saw improvements in oil pressure with this pan, but I would postulate it comes from the reduced average oil temperature due to increased oil volume (more thermal mass) and potentially increased cooling due to the pan design.

I am looking forward to the results by LBZ when he tests the pan. Even if he shows that at the same oil temperature you get the same pressure (I suspect this is what will happen), but you get lower temperatures on average with this pan (which I can easily believe), that is still a win in my book. Is the value proposition there vs. adding an oil cooler? I am not sure, but it can't hurt.

That all said, if I was building my engine now, I would probably get one because it just plan looks great compared to the stock pan, and the rest of the features are just gravy. But since my stock pan is already powder coated to match my motor, and I have an oil cooler keeping temperature/pressure happy, I am not sure I can justify the purchase to myself :baby:

Imagine that color with the aluminum fins and PPE logo machined & polished. Awww yeah.

Compared to the cost of a cooler, if the end result is the same, the pan is the cheaper and easier route.

I know a for sure fix is a higher flow oil pump, but I'm willing to try this as it's an exponentially easier thing to do than swapping the pump.

Also if one looks at the air intake testing that was done a few years ago (albeit flow dynamics between oil and air are different) the end result is the same. A lower negative pressure on the inlet results in higher efficiency and better output flow.
