Bypass filter install

It's obvious to me that you have racing car in your background.
This oil mod is a standard one on race cars where we pipe the filter onto the inner fender well.
The use of Red Line is also telling.

If you used Torco fuel, then bingo.

There's not much room for a dry sump system but we could possible use a crank scrapper and lighter internals.

What the Prius needs is a rear mounted turbo kit but again, there's not much room to install an intercooler. All that heat in the front would create a melted plastic nightmare.

Which kit did you use?

If you do the bypass make sure you do oil analysis. I think the loss of the oil additives is important too. For what it is worth. I used an oil bypass filter on a 84 Olds Ciera 4 banger. It was the Amsoil set up. I did not do any UOA's. The car died of oil blowby before the one year or 25,000 mile period. I changed the regular filter in the one year period per instructions. So I'll never go that route again. Maybe if you drive a truck it is worth it or have easy access to UOA's. It wasn't going to save that much money anyway. Car was running great when I put it on with about 115000 miles and died about 7 months and 12000 miles later.

I'm very interested! Which kit did you use?

Looks nice!

I'm curious about how you mounted the system.
Where did you attach the filter mount? Attached it to what?
Aluminum bar stock?
Did you build some kind of mounting adapter or mounting plate?

I always find it amazing how we can have different experiences using the same equipment.
I have a bypass setup on all of our vehicles and I don't notice any significant ( i.e. different than anywhere else on the vehicle) signs of corrosion on the fittings or the brackets on any of them.
I have used the Amsoil cloth braided hose in every vehicle and have not had any issues.
On our four vehicles that we presently own and the dozen or so installs on previous vehicles I have used the cast aluminum remote oil adapters and have not had any crack or leak.

I found a few on eBay for less than the retail price. One claimed to have been used for a few months, another used slightly more than one year. However, I wasn't satisfied with the hardware and plumbing provided by Amsoil in the BMK-13 kit.
1. The steel fittings/brackets were showing signs of corrosion on the fittings and where the bracket sits on the billet aluminum oil filter mount.
2. Steel fittings provided require several additional fittings, not included in the original kit, to form 45 degree or 90 degree bends, thereby increasing the amount of space required to route hose assembly
3. Amsoil cloth braided hose over rubber hose is only 1/2" I.D.
4. Typical cast aluminum remote oil adapters tend to crack or leak over time. And for some reason, the previous BMK-13 owner decided to use locktite on the nipple adapter so I could not remove it to install the 3/4x16 adapter. Or the mixture of steel adapter installed into an aluminum housing corroded and can no longer be removed.
5. The plumbing/mounting hardware are extra/spare parts from my race car. (I have enough parts/kit for another install but haven't decided when or if necessary. I guess I'll have to see what the oil looks like after some miles.)
6. Removing any or all particles or contaminents from the oil should avoid any possible sludge formation. (I would want to have any truckloads of oil dumped on my car...)

Here is a brief list of the parts I used on the Prius
1 Amsoil BMK-13 (used)
1 Amsoil EaBP90 Bypass Filter
1 Toyota 90915-YZZF2 Oil Filter
1 Canton Remote Oil Adapter #22-545
Aeroquip FBN1200 Socketless Hose
(12AN lightweight alternative to s.s. braided hose)
2 Aeroquip FCM1515 (12AN straight connector)
1 Aeroquip FCM1535 (12AN 90 degree elbow)
1 Aeroquip FCM1565 (12AN 180 degree elbow)
1 Aeroquip FBM2015 (12AN straight adapter)
1 Aeroquip FBM2010 (12AN 90 degree elbow adapter)
2 Aeroquip FBM2166 (12AN-8AN AN Male Reducer Union)
2 Aeroquip FBM3725 (8AN Port Plugs)
Stainless Steel safety wire

Mounting hardware;
1"x1/8" Aluminum bar stock
2 1/4"x20 - 1.5" teflon coated bolts
1 1/4"x20 - 1" teflon coated bolts
3 1/4"x20 nylon locking nuts
4 1/4" stainless steel washers
2 1/4" aluminum washers

Notes;
1. These pictures are from the mock up. Actual return line was lengthened since the bypass filter was interfering with the hose fitting on the remote oil adapter.
2. I've added a section of the socketless hose to cover the existing rubber hoses on the transmission that is positioned near the sharp corner of the remote oil filter mount.
3. The only modification was to one of the wiring harness brackets on the transmission. I reversed the bracket from facing downward, to facing upward so I would have more room to fit the 180 degree elbow and move the wiring harness away from that metal tab from wearing into the same harness. (I've seen other users state they reverse the cover plate so the tab will not interfere with the wiring harness.)
4. This modification has changed oil capacity +1.5 quarts. I can fit 1 quart in the bypass filter and assume the rest is based on the hose volume. Oil level now measures 1/8" from the top measurement on the oil dip stick.

(I think this is everything I can remember.)

After installing bypass filter, I haven't changes the bypass filter until now, after two oil changes. I decided to open the filter using a oil filter cutter.

I would imagine my oil filter may look like the other oil filters pictured if I had not installed the bypass filter...

Does anyone else have pictures of their oil filters cut open???

#478 shows the last four oil filters from various cars (l-r)
(1) Bypass filter from Prius after 10k
(2) Motocraft oil filter from Ford Mustang (66k miles) after 3k
(3) Nissan oil filter from Nissan Pathfinder (75k miles) after 3k
(4) Toyota oil filter from Prius after 5k
