The Stovebolt Site Forums The Shop Area Engine Shop Remote Canister Oil Filter Lines

I'm curious about the correct oil flow direction.
My ’50 216 was “plumbed” this way, so my plan is to plumb my
newly overhauled ’53 (full pressure) 235 the same way unless I hear
different from you guys.
I have a (remotely located old school) Canister Oil Filter,

The line at the bottom of the Canister goes to the Tee’d plumbing at the Oil Pressure (gauge) connection.
The other line (mid-way up the side of the Canister) is plumbed to the Block (lower centered).

Sounds right??

Thanks, Jim

It's plumbed backwards, but it will work either way. The normal direction of flow is with the line from the oil pressure port plumbed to the side of the filter canister so the oil flows through the filter element from the outside toward the middle, then it passes through a 1/16" hole drilled in the standpipe for flow control and exits the housing from the bottom fitting and drains back into the oil pan. On a 216, I believe the filter outlet is actually plumbed into the passageway that connects the oil distributor to the cylinder head instead of going back to the crankcase.

not sure on a 53 but a 55 and up is plumbed in reverse.

I think you are both describing showing, in general, the same thing:

Oil flows in a hose from the rearward port in the block into the upper/outer portion of the filter canister, and it then flows through the filter element into a hole in the central tube, and out at the port at the bottom of the filter through a hose that connects near the middle of the block.

In general, that is the same as on low-pressure engines and high-pressure engines, except for full-flow oil-filtration on 58-63 261 engines.

On full-flow-filtration 261s, the oil flows from the large forward port in the block, into the top-left of the filter canister and then out top-righ of the filter canister towards the rear of the block. As I recall, the oil pressure fitting in the upper-rear fitting on the canister (I'll check tomorrow).

Tim, there seems to be a difference in the oil return plumbing inside the block between the 54-up full pressure engines and the spray-oilers. Getting the oil to and through the filter will be the same on either one.

Agreed, Jerry

Hotrod Lincoln I have a ? can I use 1/4" or 3/8" copper tubing for oil lines on my 59 235 six ? should i be concerned about the size of the tube ? ????

Since the restrictor orfice in the filter canister standpipe is only 1/16" in diameter, whatever line you've got handy will probably work OK. The original equipment rubber flex lines that came with the dealer-installed filter had about a 3/16" inside diameter, so 1/4" hard line will be more than enough. If you're going to plumb the filter with metal tubing, be sure the canister is mounted to the intake manifold, not the inner fender. Engine movement under torque load would fatigue a metal line and eventually cause a leak and possibly a catastrophic engine failure due to running out of oil. Some people like to put a 360 degree vibration loop in a hard line installation to prevent fatigue failure, but that might be just a bit of overkill.

Thank you !!!! Jerry , You do know your stuff !
