Install of Bypass. Motor now "howells" under load above 1800rpm

SOLVED!: Install of Bypass. Motor now "howells" under load above 1800rpm

I've installed my bypass just like this one



https://www.amsoil.com/bypassfilters/2005_ram_cummins/index.aspx



however, I moved it closer "up" in the same spot and my return line rights directly right and follows "up" the valve cover to the oil return



Anyone experience this?



EDIT:

I did drop a fitting some place in the chassis, directly down from the top of the by-pass. if anythig it would of gotten in the spring/shock area or under the turbo. nothing in anyplace that would "move" like the fan. not sure if it came out, not in my driveway or garage

Would need to hear it , I would think that your pressure gage is reading good oil pressure ?
Where in the system is it hooked into ?

Get a piece of rubber and cut it to fit the mounting area of the filter head. I remember guys doing that to help stabilize the noise and humming of their fass units. Jeez its about time you add a bp filter, especially with all the talk on here about them. FYI, don't expect clean oil like gary's truck, it'll still be jet black, but a cleaner black if that makes any sense.

On 3rd gen's the oil pressure gauge is fake. All I know is it's above 7psi or something. They manipulate the oil pressure gauge based on water temperature.



I should get video of it pouring back into the filter cap to show a visual of how much is passing though the filter. . (that's a tinny pin hole! and a lot of oil!)



I may put in an order for an Auto Meter oil pressure gauge. Then again, I'll have to get a new over head pod mount that supports 3 pods. Heck, might as well get one that supports 4 and get an Air pressure gauge and plug that tube into my air tank



Then again, all I need it one hooked up temporarily to see if things are at good levels.



If I hook one (oil pressure mechanical or not) it would would it matter if the sending unit is near the oil filter housing (where I tap into the oil feed by removing that extra bolt?) or tap into the other side of the feed line AT the by-pass filter. The second choice here would make it easier to deal with hooking one up.



And what is the typical "cold" 40 degree out side "cold" oil pressure? what about at water temp of 210?

I'm I can try that. not a bad idea. Tho, I may just un-plug the filter at the feed line and see if the noise is still there.



Don't think I need to pull the filter off the new mount

Slightly off subject but I thought it might be useful information -



I added a bypass filter (different brand, same concept) to my truck at ~ 10k miles and had my turbo rebuilt after ~ 88k by HTT.



Brandon at HTT asked me about my oil filtering. He said the center section (bearings etc) was sooooooo clean and had soooooo little wear (almost no wear at all) for that many miles he was surprised. There was no soot buildup in the bearings at all, just a little surface soot that was to be expected.



I hoped the bypass filter was a good idea, seemed like it would be, but here is proof by someone that sees the results of wear on an oiled part daily.

I've added a Smarty. That's my encouragement to filter the soot out better

 

[p-Bar]

I've had the dual one on since almost new, that's the one they said not to use but have had zero problems.

 

[JasonCzerak]

so I'm going to assuming I'm not running low on oil pressure here? I should I dis-connect an wait till I get a pressure gauge. I could pick up a cheap-ish one from the auto parts store. tho I may just wanna get a real deal installed and running as well wouldn't be a bad idea.

 

[steved]

I ran a BMK-11 without any noise... a quart/minute will look like a lot until you start filling a container.

Are you set up outside to center on the hoses (oil flows into the outside of the filter, then out the center)? Not that it should have any effect on noise...

Short the system working air out, you should have no noise... there is nothing to create noise??? I think you are on the right track, remove the feed line to the bypass and see if the noise is still there.

I would buy the cheapy from the parts store would get you close enough.

 

[JasonCzerak]

I've been able to go on a higher speed/consistent speed run at lunch.



It doesn't just howell on load, any RPM between 1700-ish to 2300. over 2300 I think it's just the motor either blocking it out, or it goes away. above and below those RPM's it sounds normal.



it kinda sounds like I have an exhaust leak at times too. weird, like there's motor exhaust noise coming from the front.



I dunno, just this truck is getting louder and louder. Could it be the cold? it's 40 out this morning?



Even in parking lot you can hear the noise. not as much but you can hear it in that RPM range.



I'll remove it when I get home from work on the way to a buddies. I may pick up the cheap-o gauge and the plumbing as well to get it hooked up tonight as well)

SOLVED!!! but not fixed

That howell I'm hearing is the oil pump. It's resonating though the oil lines



I just called amsoil and explained everything. I need to insulate the lines and some sort of rubber on the firewall between the housing and firewall. 05mxdiesel your assumption is correct, similar to the FASS. I might even do that to my air dog as well. as it's getting colder, it's getting a little louder.





Ohhh and an oil pressure gauges goes as close to the filter housing as possible.



As far as a fix. We'll see about that this weekend.

I must run so much supply line that I don't get that??



I would have figured, as many owners running bypasses on this site alone, we would have heard of it before... definitely chalking it up for future reference.



Did they say why it affects some trucks and not others?

[p-Bar]

That's why mine is mounted on the engine so I don't get the noise out of it.

I suppose it could be where the filter is mounted. most mount it to the motor or frame rails right?



My supply line is about 1. 5 feet I think. the return is about the same. I'll look for some foam (like hot water plumbing in your house) insulation tomorrow at home depot. see if that helps.



I did the firewall for a few reasons.



1. I had the tools and bolts for the mount on the firewall

2. it's in a "warm" compartment. not being blasted by 70mph -17degree wind when February comes around

3. if I mounted on the frame right in front of the sway bar (where #2 comes in) debre is right there and a better change of being hit then my air dog is between the transfer case and fuel tank on the inside of the frame rails.

4. I'd have to make a mount for any other place (don't have the tools/parts/skill/whatever to do that my self)

Following is a copy of a post I wrote last week. Should help:



Buzzing from bypass setup: Had this happen to me the first time out after installing it and got really nervous thinking that I was starving the engine for oil. Parked truck and took Jeep. Emailed Amsoil and they explained that Cummins builds -in their words- "a robust" oil pump that makes a lot of noise normally. When you put on the bypass system it gives the vibrations/sound waves from this noise a pathway out of the engine and into the rest of the truck. The noise was always there. You just created a way for you to hear it. They said it's a coin toss as to whether or not a particular truck will do this. Some do and some don't. I learned to live with it and now I don't really hear it unless I try to.

Hope you fix it, go find an old floor mat or mud flap that has a flat portion and cut out a piece to fit and drill your bolt holes. I'm thinking it will work unless one of your lines are causing the problem. Not to hijack, but what oil pressure guage did you find? I been wanting to add a oil pressure and temp guage but only found the old school black autometers. I would like to match the isspro's I got that match the factory guages. Also did you t off you bp filter line for op guage? Thanks and sorry about all the ?s

 

[steved]

Mine was body mounted... . but it was also nearly 15 feet from the output of the pump and I used 5000psi x 1/4ID line... I also made my orifice diameter different to assure me the recommended flow.

[steved]

I would wonder if you changed the length of the input line slightly, if that would eliminate the resonation?????
