Bypass filter...return location?

[brista]

On my engine, on the passenger side towards the front, just above the pan there is a cast molding that looks exactly like the turbo oil return further back. There is an aluminum plug, like a frost plug in the hole. Do any of you know whats behind the plug? I was thinking of using it for oil return for a bypass filter if there are any threads behind the frost plug.



Thanks

No threads. The plug os pressed in and to remove you need to drill an 1/8" or so hole in it and use a drift pin to roll the plug out. Then you can figure out your return. Me? I pay $50 through Amsoil for Billet Aluminum oil fill caps that are tapped for Bypass filter returns. Just dimps the clean oil in the valvetrain. Can't beat it.

 

[brista]

No threads... too bad. Thanks for the info. I guess I'll look into a cap, in fact I asked my local amsoil dealer (where I bought the BMK-11) about a billet cap and he was no help at all. Does the cap come with the swivel fitting already installed or do you need to order it as well?

I don't know about Amsoil's billet cap...



But you can buy a Stant solid cap for around $10 locally and the swivel from Amsoil for around $8... drill the cap as directed and for around $20 your set.



And FYI, guys have used that port you were talking about... you buy the fitting for the port from Cummins (a turbo drain) and then braze a fitting into it to attach the return to...



You could also use Amsoil's self tapping oil pan fitting... punch a hole in the pan and screw the fitting in.



I used the Stant cap so I can monitor the flow from the bypass filter.

steved you just gave me a great idea. I may just try to punch a hole in the frost plug I was referring to and use the self tapping oil pan fitting. If the frost plug loosens by punching a hole in it the worst I have to do is replace it, or go buy the cummins fitting you mentioned. Thanks! And yes I've thought about the stant cap, swivel fitting as well, but again my local amsoil guy is no help in finding me a fitting.

You can go to Amsoil.com and order a BP-89 "Swivel Fitting". You can also call 1-800-956-5695 M-F central time 7 am. to 5 pm.

You are going to need to pull the plug if you are going to do that. If you knock it in there you have to pull the pan. I know, I done it! :{



The billet Aluminum Cap is PN BK1301 and is a pretty slick little item. Spendy, but nice.



other thing nice about using a cap (either the billet or the solid one) is you can monitor oil flow easily and oil samples are a breeze. Just pull the cap off while the truck is running and fill you test jar and recap it.

 

[brista]

Good point on perhaps knocking the plug into the pan. I suppose I'll go the cap route.

But getting a used oil sample 'after' the bypass filter - you are not checking wear in the engine but the effectiveness of the bypass filter to remove any contamination and wear particles.



A used oil smaple should come before the filter to accurately measure 'engine' wear - not after the filter. It's no wonder all the Amsoil oil samples have low numbers - it's post bypass filtration!

Not really. ALL the oil goes to the sump from the by-pass return, so it makes NO DIFFERENCE where the sample is drawn from. The important thing is to sample from the same place all the time, and have the engine at operating temperatures.

thats exactly what we do here in maryland, the stant cap at least

I agree with Wayne on this one... if the bypass is working correctly, there should be no detectable difference between that in the pan and that after the bypass...

I liked the idea of returning the clean oil into the valvetrain galley but the gadgets that install in the filler caps looked pretty cheesey to me. I simply took the valve cover off, drilled and tapped a hole in it and ran the return line that way. Looks very clean, almost like the factory did it.

I eMailed Blackstone a short while back about testing post filter, and this was their response:



Hi Tom,



It won't make much of a difference where you take the sample, because the

wear metals that we look at are too small to be removed with the filter.

What you will see a difference in, taking the sample post-filter, is the

level of insolubles--they should be low, since the filter will have removed

most of the solids, if it's doing its job. In fact that's a good way to see

how good a job the filter is doing, so if I were you, that's where I'd do

it.



Hope this helps!

Just not true Wayne. It will definitely effect your results.



Hmm, let's see, drink purified water directly after filter or from the 12 times larger pool with other contamination sources? Yes, in theory in a static system, it eventual should look all the same but an engine is not a static system and you'll see a difference.



Sampling from the output of the bypass filter - if the filter is working properly, you will never see any engine wear particles because they are in the 'filter'. If you want to trend oil properties this is an okay convenient location. If you want to trend engine wear, then you should be pulling a sample from the pressurized oil gun rail - this is the oil that is coming out of the engine.



I am STLE CLS and OMA certified and where you draw the sample WILL effect the oil ppm results.

It appears that the Blackstone contact was talking about the standard spin-on OEM type oil filter - which is a true statement in that the OEM style spin-on filters are typically rated to trap particles in the 15-25 micron at 50% efficiency and vary from 25-40 micron particle size when they get to 98-99% efficiency.

However, a good bypass filter should filter down to 0. 5 -3. 0 micron size particles.



The lab, uses either a spectrographic oil analysis machine or possibly an ICP machine, which can only see particles up to 10 micron or smaller. So you can see the confusion in the answer from Blackstone - taking a sample after the standard oil filter would NOT effect the used oil results but taking one after the bypass filter (outlet flow) could definitely have an effect on the particles - I think if you contact the gent at Blackstone and confirm the use of a bypass oil filter that his answer will change if he understands oil filtration.

IMO, a filter will not affect the oil analysis results because it is in PPM... it would affect the particle size analysis...

I need to get one of these as I built the mounting bracket yesterday. The only thing holding me back is a return now. If you order from Amsoil's online store do they ship to you from the closest warehouse?

Yes and they charge you taxes if in your state...



While the billet cap is nice, the stant cap is slightly cheaper...
