How do you all like your remote oil filter setups?

Thanks for the answer! Well when I get the valve I’ll see if I can test it & see at what psi it opens. I wish we knew which valve GM used in the marine/industrial
engine blocks. Only other thing I know is mine was from Tonawanda NY not Romulus Mi. That’s the 2 plants that built the 4.3s….

I honestly think by the time the 90s rolled around, the blocks on the line were all the same and just were boxed and sent wherever. The last marine 350 I tore down (original to the boat) had the same cam in it as my 00 c3500. Casting numbers and all.

I think pretty much all s10s had an oil cooler too... so most of the 4.3l engines probably had a higher bypass pressure even without the remote filter...
