I Am Plumbing 2 Bbc Oiling Systems #12 Earl Hardin 3/4 Fitting Oil Filter Adapters 3/4 Fitting Oil Filter Mounts For #6 Fram Style Filters 3 Inch Ss Oil Coolers Do I Run The Oil Out Of The Block Into The Filter First Or Into The The Cooler First I Can See A Reason For Both Ways So I Am Looking For Your Thoughts Thanks For Any Input

Recommend that you use a Thermo Oil Filter unit from Keith Eickert. Especially effective when using a big oil cooler. The thermo unit controls when the cooler gets/or not gets oil. I believe (to answer your question), oil gets cooled before being filtered.

thanks and yes i am using a therm. control just did not mention it I also want to run it though the cooler 1st but thought hot oil would flow thought the filter better

On my Gen4 blocks I run 12 out of the block. (OutsideHoles on
filter pads) to a Canton remote oil tstat to 24 inch x 6 inch diamiter coolers. out of cooler back to filter pad then back to block. My thoughts were that I wanted the filter right before the oil returns to block to catch any debris that may have been in the hoses, cooler or t stats.

I like the idea of the KE filter pad better because of the
pressure loss I am getting via the lenth of all the -12 lines.
I would still put the filter pad after evreything else.

Just my thoughts

FWIW Teague goes to the cooler first then the filter.

I highly recommend this approach on any rebuilt motor as there is no foolproof way to clean the coolers.

I thought I read somewhere, that your suspose to filter the oil when its hot, then to the cooler. I could be mistaken.

Most oem coolers cool less than 25* in one pass, Teague's double pass offshore oil cooler cools 50* in one pass.

In other words there is not that much temp difference to be a factor.

Here is a diagram if this is the remote thermostatic filter you have. If you have any further questions call Jeff @ 386-446-0660
