I have been researching Oil By-Pass Kits, but I am not getting very many options.

What brands are recommended the best quality?

I have researched Amsoil, Frantz and FS-2500.

• Not great reviews on the Amsoil.
• Frantz seems ok, but still looking for an alternative.
• The FS-2500 seems way over priced compared to the others.

 

I bought an OilGuard system myself for my truck, then built my own using the same parts from Racor for my second system. I would research and buy the Racor parts again for another system.

The Racor initial parts prices and replacement filter prices for the LFS 801 and LFS 802 are nearly identical, but the 802 is almost twice the capacity and can be used for twice as long. You just have to orient the 802 at an angle which is no problem, and it's how I'm running my 802 system on my truck right now.

The OilGuard system for the 7.3 is the exact same as the Racor LFS 801, but you can part it together yourself for less money. Again, go with the larger 802 unit for longer filtration life and less expense on oil changes.

 

I built mine using Ken's (wood-n-things) plans. Got the parts from Grainger and Parker. Really liked the detail drawings and part numbers included. Do a search on here and you should find it.

I like the bracket that mounts to the transmission right near the full flow oil filter.

Can't remember whose kit has that bracket, but if I had an oil bypass system, I think I'd want to make one of those types of brackets that sandwich mount with the transmission torque converter inspection cover plate on the driver's side. I'd size the filter canister accordingly.

 

I did the same Oilguard Bypass as Pete mentioned above back in 2006. I had the Amsoil one prior to this but I prefer the Oilguard type setup. The Oilguard filter housing is solid and can take the hit from just about any type of road debris.

 

I have NUC system from EBay. I have been very happy with it. It uses Amsoil EaBP100 filters.

Seems this is a good investment for those that drive their trucks daily or a LOT of miles over the course of the year. In my case, I may drive 2-3k miles a year...which equates to an oil change every two years. While this kit may extend the interval to 10-20k miles, I can't see leaving the oil in for 5+ years. So doesn't seem this would benefit me...no?

 

I have the Oilguard sytem also. Only complaint is the cost of the filters has shot up. They used to advertise the filters being much less expensive than the competition. Have you considered running the Donaldson ELF 7405 oil filter? Filter and by-pass filter all in one. Cost would be about the same as changing oil filter and by-pass filter.

 

That depends on how many miles are already on the truck. I put up to 20K miles on Stinky each year, and he's nearing 300K. An oil change every three months. I don't think I can extend my oil changes, but I can make the oil cleaner for those 5000 miles. High-mile engines are more likely to soot the oil from exhaust valve guide and piston ring blowby. Soot in oil is akin to Soft Scrub.

 

I'm at 165k miles....do you consider that HIGH mileage for a 7.3L I guess from my perspective it could be a good investment to provide more/better filtration as opposed to extending oil life?

 

I don't really consider 165K on a 7.3L high... but the line is fuzzy because of the varying lifestyles these engines lead. It's not like I could say it doesn't need it at 198,237.5 miles, but it does at 198,237.6.


Can you imagine that? Uh... honey? My odo just hit 198,238. We have to stop and install the oil bypass system - so as not to blow up at 198,238.5 miles.


It can't hurt at any odo reading.

 

That would be why I would use a bypass filter... for better filtration, as opposed to longer oil change intervals. Since the injectors are hydraulically actuated, keeping the hydraulic fluid free of soot would be my motivation.


I guess it hasn't been enough of a motivation, because I still don't have a bypass filter system. But that is because I was changing the oil every 3,000 miles... which amounted to once a year. Oil still has dark amber tones when it is dropped.


I finally switched to full synthetic. Last oil change was in 2012. I have less than 1,700 miles on that oil. That's hundred, not thousand. Do I drop 3.5 gallons of T6 at between $22 to $39 retail per gallon, just because it has been 2 years now since it was last changed?


So yes, I understand what you mean.

 

Seems like a wise, "preventative" investment I guess....just like I did recently with the Coolant Bypass system. I guess I'll buy a kit over the winter and put it on along with my quick drain plug that will go on during next Springs oil change :-)

So probably a silly related question....when you have a bypass filter kit, do you change both filters at the same interval when doing an oil change? Or in my case, each couple years?

 

With my classic Mustangs (82 GT 13k mile survivor and 85 GT 15k mile survivor), I run synthetic and the 2-yr rule no matter the mileage. Some say it may last years longer, but I figure what the hell....they are classic show cars that deserve some love every couple years regardless of the miles. It's just simple preventative maintenance IMO at a low cost every two years.

I've always treated my 94.5 PSD by the same rule of thumb, and will do so with this truck, along with the extra filtration.

 

DIY system here...fleetfilter.com for the base and filter. Piece of angle iron to mount base to existing holes in frame. A few "AN" fittings and push-lok barbs, some fuel/hydraulic or whatever lines you prefer for plumbing, and go at it, at the install...about $30.00 total in parts.

Once you do this, you'll then pheen to do the trans by-pass..lol
