Amsoil bypass best option for my Toyota?

[Muffin Man]

I'm looking at the Amsoil bypass oil filter kit (#13). My main reason is that I want an oil filter relocation kit and the Amsoil kit seems like the best built option with the best installation instructions I've seen. However, I have two concerns regarding the use of this kit.

1) It's probably overkill for my purposes
2) I'm concerned over the possible low oil pressure I may experience with a bypass kit.

Are there any other high quality oil filter relocation kits? Are there any issues with the Amsoil bypass kit that I should think about before taking the plunge?

My primary reasons for the kit are simply to put the oil filter in a better place. My 3.0 V6 engine is a PITA when it comes to oil changes. I already use synthetics and change the oil and filter every 5k to 7.5k miles, so oil quality isn't my chief concern. It's convenience.

Any help is appreciated,

Excatly why are you concerned about low oil pressure with the Amsoil BMK #13?

I haven't seen anything on this, no warrenty problem, no consumer complaints nothing.

I even know a guy that has one mounted in the back of his PT cruiser with like 16 feet of hose and the oil pressure is still good.

If you simply want to relocate your oil filter shop around the high end speed/motor head web/catalog auto stuff. There are plenty of options - most do use the same aluminum castings -which have been used on many applications with no issues.

As Pablo says, there are plenty of standard filter relocation kits available from Jegs or Summitracing.

Since you're going to the trouble, it wouldn't be unwise to use an Amsoil setup to gain the advantage of bypass filtration.


The only pressure "loss" in the dual setup is due the biasing valve that simulates a more restrictive full flow filter. This enables more flow to the bypass filter. If you want to eliminate this pressure drop, you merely remove the biasing valve from the dual mount. It will reduce the flow through the bypass filter until the full flow filter accumulates some debris.

Just to give you an orientation to how this works ...

You won't see a loss of pressure ..typically. What really occurs is a pressure elevation upstream of the filter. As long as this is below the pressure relief of the oil pump ..there is no loss of flow. In the event that the pressure relief limit is reached, then flow is reduced. This surely can happen, but I believe that it is rare and brief in the instances that it does occur. Usually the pressure elevation falls within the confines of higher visc oils in a cooler temp situation.

In short, few worries.

I agree with Gary Allan. The biasing valve will increase the upstream pressure but as long as this does not exceed the engine's built-in pressure relief valve setting, the pressure your engine sees will not be affected. To be safe, use 0W-30 oil which will have low viscosity with a cold engine. I also suggest that you install an oil pressure gauge so that you are certain you are getting good oil prssure.

Good luck finding a place to put the BMK-13 unit. My wife's Highlander has the 3.0 liter engine, and I couldn't find a place to mount anything. I settled for installing a Trasko filter. IMO, the Trasko doesn't hold a candle to the BMK-13 unit (Which I installed on my Honda S2000), but is very easy to install and maintain.

If your Toyota 3.0 is one of the years that had a sludge problem, you may want to reconsider installing a bypass filter. If the dealer found that you have extended your OCIs, they would not repair/replace your engine if it failed due to the sludge problem.

You can always figure a way to mount it on the outside of the fender, and go down the road like the big rigs do.

Ah, ****! Glad to see you that you're stopping in from time to time.

When you look for a place to "place" your remote mounts, don't limit yourself to rigid fastening. You can lash it fast to just about any location with zip ties. This is not a natural act ...but once you get over the alien feeling, works just fine. You then have the advantage of just leaving some slack in the lines so that when you snip the zip ties, you can place a pan under the unit to catch any drippings.

You've got to think in 3 dimensions ..not just in flatland. There's usually some "space" that's far enough away from rotating parts to fit the unit under the hood. You then just fasten it to whatever is there

Really?...I don't think so. The Amsoil biasing valve cannot change the upstream pressure above the regulating valve set point and does lower the downstream pressure. The engine oil pump pressure regulating valve only sees the pressure out of the pump, not the pressure going to the bearings, and holds that pump output pressure near constant. If the resistance to flow is increased, the pressure regulating valve will maintain constant pressure by dumping more oil to the sump. The oil pressure gauge may also only see pump output pressure depending on its location. Mine is on the filter inlet. The Amsoil dual-bypass kit certainly does reduce both oil pressure and oil volume going to the engine.

No two ways about it..

When mounting the bypass; keep in mind that it will have a resonance from the oil pump. If you mount it to the body anywhere, you will be able to hear this in the cab. (I didn't know this and had to remove mine and put rubber under the bracket I made and under the AmsOil mounting bracket).
Assemble the bypass with a filter and open the hood and start 'placing' it in different areas 'till you find a suitable location. If you put it underneath the vehicle, be aware of possible road hazard damage.

I would like to see some info on how much AmsOil bypass units do drop the pressure. How much more of a pressure drop is it over just the factory filter installed on the engine? The engine doesn't need to be starved ANY of it's vital 'blood'.
