Anybody use or see this bypass oil kit

What are your thoughts guy's?

If done correctly it can't hurt but their claim that the oil will remain "analytically clean" is a bit off. Assuming you have a good filter the thing that you see in oil analysis is that the additives break down. That isn't going to change with this.
They don't have a diagram to show what exactly this system does so had to piece it together from the install information.
- It does not replace the stock filter. It is in addition to the stock filter. It connects to the pressure side of the oil system and dumps to the oil reservoir.

Obviously the aircooled engines don't have a problem with contamination related engine wear so I see this as a real limited benefit idea. If I wanted to plumb in a system to go after a known source of engine wear I would look at an Accusump.

The quantity of wear that comes from the startup portion of the engine's use is sizable. The first big example I saw that demonstrated this was in the early 70s when the Alaskan Pipeline was built. My dad was the only GM certified partsman in the state so he got to see a bunch of examples. The Chevy big block of the day was pretty well known for eating cam lobes at 60-80k miles but they started see a large number of big blocks in trucks getting their first internal service at 250K miles which was completely unheard of. All of these trucks were from very far north being used for pipeline and oil field work. Even though they were being used in extremely harsh conditions the engines were lasting 3 to 4 times as long as normal.
Why? Because they never shut them off. They were run 3 shifts a day and weren't shut off even for refueling. (When it can commonly get 70 below you get used to leaving a car running.) They only turned them off to service them. The result was the trucks run under this kind of "punishment duty" weren't being punished, they were just loping along and never seeing the wear from a "dry" startup.

Really makes a strong case for a preoiling system on an engine.

These things have been around for 50 or 60 years with all sorts of extravagant claims being made for them. Rolls of toilet paper were never intended to filter oil and can vary greatly from one to the next. If you are the sort of person who thinks wiping his ass with an oil filter is a good idea then filtering oil with toilet paper might seem OK. Just for the record, there have been documented cases of bits of TP breaking loose, clogging oil passages, and ruining engines.

you can't be serious? soak a roll of toilet paper in oil and watch the results.

This is not a toilet paper roll filter.

Respectfully please tell me why it's a bad idea?

[gomezoneill]

I'm not supporting the product but it's not a toilet paper filter. Just wondering if it's a viable product.

For one thing, the oil analysis in that example is from a diesel engine. Used diesel oil is loaded with soot particles that wouldn't be present in our oil. Notice their specific kits are for diesel trucks. There may not be that many particulates in our used oil, but I haven't tried looking for a particulate count from a 911 oil analysis.

I'd also be worried about how much flow this thing can handle and where it would fit in the oil loop. You don't want to starve the pressure side of the pump. I don't think there is a lot of pressure on the scavenge side that feeds the filter, so if flow is reduced through the filter, then you may not get enough oil to the pressure side of the pump. At least I think that's the way the system works.

Good points there.

Toilet paper filters are what this company has always made, and a roll is pictured in the link you provided. Don't mean to be a wet blanket but you asked.

I know it looks like a toilet paper roll but It's described as a cellulose filter.
Don't take offense guy's I just like to know if it's a viable product or not.

Paper is cellulose. They can call it "filter medium" if they want but it's still a roll of toilet paper.
