I have been anxiously waiting for time to cut this one open since I pulled it off. Looking down the barrel I saw some sludge and was wondering what id find on the other side. I found some sludge, but nothing like I thought it might be.
This was on my 83k20 plow truck. Saw about a year long service with Trop-Artic 5w30 plus a can of seafoam in the crankcase.
All in all, rather unremarkable.





No ADBV and no bypass.
Figured the sludge on the inside of the filter must have washed down when I poked the hole in the bottom to let it drain. The Flow must have washed some down from the block above.
Let there be no doubt that seafoam in the oil works!
No tears and wavy pleats due to the cold starts, or so I would assume.
