Baldwin B50 on my Buick PA..... FINALLY

[Gary Allan]

You appear to grasp the essentials, beanoil. (cough-cough) ..keep in mind that you can get a BP80A from Amsoil w/filter for about $50 retail.

What engine is in this tow vehicle?

 

[beanoil]

The truck has the 5.4 Triton made in Windsor. I am happy with it's power, and highway manners when towing my TT. I am currently running Schaeffers 5-30, and an FL820S. While this is probably a good combo, I can't help but think the added benefits of bypass will give me a little insurance when towing. I did check a local supplier for the B50.. a whopping 2.47 per filter, and 29.00 for the Baldwin head mount. Thanks for the heads up on the AmSoil set-up. I'll look into it.

That's cheap enough to change the B50 quite often. Good prices.

After reading the suggestions on bypass filter flow rates in this and other threads, I measured the rate through the Balwin bypass setup on my Subaru Forester (BT314 - small version of B50). After being in service about 9 months, the flow rate was almost exactly 1 qt/minute at operating temp idle. Since this is a small engine, and the flow rate was much higher when the filter was new, I wanted to lower the flow rate. Some posts have suggested rates as low as 1 pint/minute for smaller engines.

I added a 0.031 restrictor fitting this morning and, based on observing the flow, the install appears to have been successful. I have not measured the flow rate yet, but I am guessing that I am down around or below 1 pint/minute (which will of course increase when I next change out the filter).

 

[Gary Allan]

Good work. I think that you'll find that the flow change will be squashed over a longer period. Let's say that new the filter would (just pulling a number out of our behinds) 3 gallons a minute with no restrictor. The built in restrictor limited that to 1qt/minute. Now that rate should be, for the most part, constant (at that pressure/at that oil temp) until the filter can no longer pass 1 quart a minute (at that pressure/at that oil temp - same visc). The restrictor at that point has no flow to restrict ..it's just passing it through ..no pressure build up..etc. By putting a .31 restrictor, you should elongate that process.

What and where did you install the restrictor? have the B50 on my diesel and would also like to slow the flow a tad bit

 

[DaveL]

I installed it at the return, which for me is to the oil filler cap. I'm not sure if it makes a lot of difference where in the line you install it, since there shouldn't be anything in your oil too big to get through the orifice, but I still felt most comfortable putting it after, rather than before, the filter.

DaveL,

I have been looking for a restrictor and wondered did you make it or purchase? If you made it what size hole did you drill? If purchased where

I bought mine from Tomkins Industries http://www.tompkinsind.com/adapter_univ/fittings.asp
Part number RST 1404. If you search on part number, just enter "1404" and the RST (restrictor) versions will be shown, along with the non-restrictor 1404s. I used a 0.031 orifice size. They offer several orifice sizes and also a blank if you want to drill your own.

Just as a follow up to the B50 I did my UOA on CTD with 5400 miles on oil....Particle count was 16/15/12...with just stock filter and same lot oil it was 19/16.

I used a WIX filter with Rotella T 3 gals and 1 bottle SLOB, my new oil used was Valvoline and SLOB with Wix EX version

See the complete results under Diesel UOA
