My truck is over at Big power diesel getting some new injectors and a air doggII . So i was thinking since im adding extra filltration for my injectors and fuel system i should do the same for my engine oil. So im gona switch to sythetic oil next time I change it and getting a bypass kit to complement the synthetic and the fleetguard free flow i have on the truck now.

Im looking to drive my truck to into the ground and want that date to be a long time away. So what bypass kit is the best bang for the buck on initial purchase and overall ownership.

chris the first thing to do is to change the camshaft out. your 06 has in cylinder egr. by changing cam, adding 35 hp nozzles and smarty jr you can increase mpg by 40% and reduce oil soot by 75%. the soot loading is the determining factor in oil change on 04.5 to 07.4's. you can not get even one more mile out of synthetic verses dino unless you make this change.i run about six different brand of bypass filters. keep what i tell you in mind when deciding the one to go with. the dirtier a filter gets the better it filters. the bypass filter does not have a built in bypass valve. the point where it filters the best is just before it clogs up. run the filter until it is no longer warm after a run. this time interval spread is huge between the various ones. frantz is the lowest and filters next to the best and is about the cheapest to run. if you do not do the mod you will have to change the frantz about five times between oil and filter change. the longest interval filter is the luberfiner 9750. it has very good filtering with the ability to restore the oil tbn. this filter was made tor the common rail large trucks running extended oil change intervals. it will go about 75,000 miles per change. the down side is it is not carried by local part stores Ryder truck is the best source. it holds about one gallon and is best to drain it at every oil and filter change. it is also expensive. it also has to have the restricting orifice size reduced for use on the small 5.9. the other brands are in the middle of these extremes. they do not filter any where as good as these two but are easier to get. and kits are available that has all of the feed and return parts so if you are not technically inclined a kit like the amsoil would be best for you. out of all of them i like the luberfiner the best and when you figure the cost per mile it actually comes out the cheapest. one filter i did not mention is the best, uses no cartridge and is virtually maintenance free is the centrifuge filter. no one was running them on the 5.9 because of return oil problems. they just now started to add a small return pump making them practical for our small 5.9's if you chose one like the luberfiner pm me and i will help with getting parts and mounting.

 

I have Amsoil on one of my trucks and Frantz on my CTD.

 

Carl,

Would one of the 9750 filters screw into the Amsoil base? I am looking for an alternative filter to the Amsoil EABP. Do you got any reading material on the specs for this filter?

Also the site says they do not reccomend returning oil through the valve cover, why is that?

Edit: I found some info on it.

• Rated Flow: 5 – 8 L/min (Inlet pressure dependent)
• Flow Loop: By-pass/kidney type application
• Diameter: 135 mm
• Height: 320 mm
• Media: Co-pleated louvered Zn and synthetic/blend
• Zn surface area: 2.36 m² (two sides)
• Mass of Zn: 635 g
• Media surface area: 1.18 m²
• Efficiency of base sheet: 98.7% @ 2 micron
• Volume of oil additional: 3.785 L

 

Im into getting rid of the incylinder ERG but i doubt the helix cam or other brand would pass emissions or would it. CA has the snap test and smoke is the biggest problem or concern for me. I can turn the smarty down to halh power but im not sure that will work.

 

Tell me more about this in cylinder EGR. I have a Cali 06 as well.

 

All u need to know about in cylinder EGR https://www.dieseltruckresource.com/...t=cylinder+EGR

 

the 9750 will not fit the amsoil base. the luberfiner base is LMB451. the best place we found to mount them is horizontally on the frame. the orfice is in the base but is to large for our trucks. i make my own and place it in the supply line fitting at the stock filter housing. with the reduced flow to the valve cover it is no longer a problem. the helix cam is more suited to the younger generation. the pdr cam is best for readily available cams. if you have a little time colt, hamilton or f1 will custom grind you one. i never figured out how to post pictures but if you want pix of install pm me with your email address and i will send. the cam change does not effect the snap test at all. it can not be detected in the California test

 

Oh ok thanks. I already have the Amsoil bypass. I will just stick with it. And hope I can find a cheaper 2mic alternitave at some point.

To post picts you can upload the to www.imageshack.us It will allow you to upload multipul and then resize them. I used 640x480 to resize. Then you copy the direct link on the right size of the picture. Click the botton on here that has th mountian thing on it, and paste the link and it will post the pict. Or you can just paste the link to the album and we click the link to see all the picts rather then each one eing posted here.

 

A bypass filter does not add to the longevity of the engine.

It allows you to run the oil longer, though. If you're on the road a lot, changing oil and filter every 7,500 miles is not very convenient. For those people, getting 12K-15K miles between changes is a real time saver.

To get the most out of your engine use a good diesel synthetic, the best filter you can find, and change them according to the UOA.

 

I don't quite see how running a bypass wouldn't extend the motors longevity. If you are filtering out more particles that would typically be floating around yor motor causing damage to your cylider walls and rings, would that allow your motor to run longer?

 

Hi boB,

You said this:

Would you care to elaborate as to why a bypass filter does not add to engine longevity?

 

Engine longevity depedns on clean oil - among other things. How you keep the oil clean doesn't really matter, as long as it's clean. If you drive a lot of miles and don't want to take the time to change the oil, then extended intervals with a bypass filter is really a good idea. Otherwise, jsut use whatever oil you like and change it at the appropriate time. The end result will be the same.

 

Wouldn't the bypass clean the oil? Thus increasing longevity?
