so theres no real reason that i should do this mod ?

 

The SAE just did some papers on the benefits of bypass filtration. Very impressive figures on how much longer your motor will last. Check out this post:

As he said above it provides better filtration, but also increases oil capacity so on our Diesels it keeps the engine in a happier/clean state between OCI's. It is also supposed to provide a longer times between OCI's.

I personally don't think it's worth the cost of the extra oil, filters and cost of the unit. Possibly on Fleet vehicles that are used/abused and the OCI is erratic. The stock unit for the normal drivers are plenty as long as you go by the book on OCI, Fuel Filter changes and Air Filter not to mention quality fuel and additives.

The little 3cyl Diesel on my mower came with an oil-bypass mainly because the filter was in a horrible place to change out. Now it uses two of the same filters and more oil, but this is a totally different beast. I only change the #2 filter every other oil change. It's only $3.50 a piece.

 

Yes Jocaren the is no reason you should not do this mod. BUT...You should be aware that you are bringing in a system that can actually do you more harm than good it not installed and watched. There have been very lengthy discussions on this and if you are going to base your decision on this discussion you have a 50/50 chance of being happy.

My advice is to read mrxlh's post and then do some heavy searching on this forum and some of the other forums to make a decision. Remember your truck will be fine in it's stock form as long as it is taken care of by you. Adding the Oil ByPass brings new things into the equation.

Good Luck and Good Searching!

 

....hum...Welll I have run and will run an OilGuard on every truck I own.
Never one problem, never any issues with the dealership or Ford.

 

My Blackstone reports since day one have been between .2 and .4 insoluables and as my mileage went up... I now have a consistent .2 - .3 insoluable reading... which no one with a by-pass oil system can beat with consistency?

Over the past 3 years (since owning my '03 6.0L Excursion) I have tried to have people post their oil analysis reports and "prove to me" with oil analysis that their reports are better than mine with just the stock set-up. Only one person has done so and his insoluables (soot reading from his lab) was only 1/10th better than mine.

I ran Motorcraft 15W-40 for the first 50,000 miles and now use Rotella-Syn 5W-40. I use only Motorcraft oil filters (Racor made) from my local auto parts store. I change oil & filter every 5,000 miles like clockwork.

How is it that my oil analysis is as good as 99% of those running by-pass oil filters? How come the by-pass oil filter people do not publish side-by-side before and after reports of analysis to prove what we think happens in therory?

We can debate all day long if by-pass filtration works... but the idea of possible reduced line pressure and the fact that not may post their oil analysis for comparisons leads me to think that there are more "smoke and mirrors" to this mod.

Keep in mind, I would like to buy as I believe in the therory... I am just looking for the hard "statistical proof" that it is money well spent.

 

I guess I should have said earlier the OilGuard was not the system that was on our fleet vehicles. I just know they are all sitting on a shelf now.

 

How about documented proof from SAE on the effectiveness of bypass filtration:
I quote another Forum member:
"Thought I should report something from the Society of Automotive Engineers technical papers on bypass filters.From SAE #710813 we get an increase in lifepan for the following components switching from a 60 Micron FF to a 60 Micron FF with a 3 Micron bypass: Top ring +900%, second ring +562%, oil ring +422%, rod bearing +300%, main bearing +261%. This was from a Cummins motor test, not a filter manufacturer.From SAE # 930996 we get a test comapring a 40 micron FF to a FF with submicronic bypass (centrifugal):top ring +792%, second ring +1000%, oil ring +229%, connecting rod bearing +750%, exhaust valve components +282%, piston pin +1000%, turbo bearing +1000%.This was from Glacier, a filter manufacturer.According to SAE 2001-01-0867 we can expect an absolute 2 micron bypass filter to remove several orders of magnitude of transmission fluid contaminants compared to a conventional automatic transmission.If I read the charts right this implies a 300% improvement in the lifespan of the transmission. There are about 20 papers relating to filtration efficiency in engines. One of the most important was done in 1946. This paper showed that full flow filtration cut engine component wear in half compared to the bypass only filtration that was common at the time. They should have kept the bypass when they went to full flow!Several other papers stressed that filtering below the 5 micron level , and even into the submicronic level resulted in large improvements in the lifespan of most engine components including the timing chain, and seals. "

 

Does anyone know what the Racor/Motorcraft oil filter micron rating is? Is their a website or has anyone ever called Racor? Just curious because I believe (no proof) that the Racor/Motorcraft oil filter filters at a better rate than 60 microns as tested in the above test. I know that this isn't an apples-to-apples test, but I believe that a 60- micron filter is not that good of a filter... to start with.. so any improvement will yield better results.

 

To filter submicron you get too much restriction to be a full flow filter. Filtering sub micron is the best for bypass filtering. There are many folks out there who have taken gassers to upwards of 350k miles without changing their oil at all.
Proof of the benefits of bypass filtration. Only adding make up oil when the filter elements are changed. The full flow filter u use probably filters to the 20 micron
level as it is limited in size to filter much lower.

 

OK guys.... I will now change my mind on by-pass oil filters!!!!

So listen up....

I called Racor/Parker just now and spoke with a gentleman by the name of Dave Kline. He was a big help and knew his "stuff" about oil filtration and knows the 6.0L motor very well.

In bullet point format for easy reading here is what he stated:

1) By-pass filters work.

2) Racor makes a by-pass oil filter kit for the 6.0L motor.

3) Their kit (could not speak of others) filters about 5% of oil at any one time.

4) Ford does not use a by-pass oil filter due to the "average person" not needing it and cost - Ford is trying to reduce costs!!

5) The Racor set-up seems simular to the Oil Guard set-up just by what he described on the phone. Purchasing must be through a Racor distributor.

6) Ford is aware of by-pass oil filters and has tested them... but due to cost, they do not offer it from the factory... but they use a 2 filter set-up for the fuel and they use a by-pass filter for the tranny.

7) Racor makes the OEM oil and fuel filters, but NOT the tranny by-pass filter.

Now the kicker... traditonal oil filters filter between 30 - 40 microns.. and the oil filter IH and Ford picked for the 6.0L motor filters at 20 microns right out of the box!!!!

He stated that "normal driving" and regular oil changes will yield good results due to the lower than normal micron rating of the stock filter... but if someone wants better filteration than stock.. then a by-pass is the way to go.

He stated that due to the capacity of the oil pan and system (15 qts), that line pressure is not a problem. There is no drop off since it is by-pass system and if there was... the injectors would not fire properly... hence you have other problems.

The Racor kit for the 6.0L motor (from Racor) is LFSRK860F. The replacement by-pass filter is number LFS801BPE.

The stock OEM oil filter (that cleans to 20 microns) is filter number PFL2016. This is why non-Racor non-OEM filters have problems... since they do not filter to the 20 micron level that a Racor filter does.. for a stock filter!!!!!

I was sent a PDF file of their by-pass set-up and a graph showing the effects (improvements) of their by-pass set-up. The by-pass filter they use is a 1 micron filter. What I did learn is that they do oil testing analysis as well as other oil testing instruments.

Can't send emails to everyone, but is there a way for a MOD to post a PDF file to this site or thread since it is relevant to this thread and is another option for by-pass oil filtration.

So with that... I now proclaim that I will now endorse by-pass oil filters (at least Oil Guard and Racor) and the use of Racor made OEM filters for optimum performance... with or without By-pass oil filters!!! If Racor, IH's and Ford's OEM supplier endorses their usage... then I will too!!!!

Thanks,

Jeff

 

I am very pleased that you finally filtered through all that information and will no longer bi-pass the secondary oil filtration issue.

 

I'd like to see their setup...I went to the site, but it's the same nightmare of navigation that I remember before.

Beach...Can you provide a partial link. The part number for the bypass doesn't show up on their site.

 

The planets have realigned! Call Keith 'butter' cuz he's on a roll. Mr. Lamkin is smiling as well....

 

I told you it worked three years ago!
