Restricted orfice at the oil filter?

Dan

Which begs another question, oil pan-wise: is there a finned aluminum aftermarket pan available? It would help cool the oil and be less likely to warp than a stamped pan. And would look WAY cool...

Happy Tractoring!

The HOT thing with the Dodge/Cummins, Duramax, and Powerstroke owners these days is to ADD an aftermarket bypass filter to keep the fine particulates from building up in the diesels' oil.

Kinda funny how this old technology is "new" again!

The link below is to an ad for one such system:

• Filter

It seems to me the average is reputed to be about 10% of the oil pump's output that flows through the filter.

(On modern units, ALL the oil pump flow is supposed to pass through the filter, before entering the various oil galleries.)

With this BYPASS SYSTEM, with NO restriction, too much of the oil pump's output would pass through the filter, and get "wasted" back to the crankcase, and oil pressure would likely be way too low, possibly to the point the bearings would be "starved" for oil.

You say the restriction is in the brass fitting?

There has been some discussion here before as to whether the restricion is an oriface in the filter can, or in one of the fittings. Does your's have a tiny hole in the "can", where the oil enters? Likely, there is a tiny hole near the top of the filter cannister's ollow center tube that restricts the oil LEAVING the filter.
