Oil flow chart

[SteveR]

Hi Guys, I recently had to replace the brushes on my 1937 Plymouth starter motor. In order to remove the starter I had to remove the 2 oil filter hose to the engine. Unfortunately the hoses have perished and I had to replace them. It took a while to get new brushes here in England and I forgot which hose went where. 

 

My engine is a 1951-52 dodge. I looked on the internet and I have seen 2 ways of install. 1) bottom hose to pressure side & 2) bottom hose to return.

Which way? Thanks for your help

It will depend on how your filter canister is configured. Some feed in pressure from the bottom, flow oil from inside-out through the filter, then return out the upper side of the canister. Others feed in on the upper side, flow through the filter from outside-in, and drain out the bottom center. Some canisters are marked IN and OUT next to the ports, and some aren’t. Maybe some pictures of your filter canister will help identify which type it is.

Thanks Merl for your comeback. Your an early bird this morning. I'm from Minnesota so I know what time zone your in.

 

Hers a photo. No markings re. 'in' or 'out'

Steve, 

Is that picture from before you removed the hoses? It’s hard to tell which way they’re connecting down below, but when I zoom in on it, it looks like the upper one may be going to the drain back port in the block. 

 

Here is a thread from last summer on this topic. Unfortunately Dodgeb4ya had some great images form technical pages showing the different filter flow setups, and the pictures are now gone. Maybe he can repost them for us?

Hi guys,

 

Bumping this up for clarification.  Ive got a bypass oil filter like the one on the left in post 5. inlet on the top.  Id like to clean the filter housing and lines as they are really dirty and havent been installed for years. Id also like to know proper installation instructions.

 

Does the hex head on top fully unscrew for cleaning? 

Is there any gasket/seal between the hex head and the "terminal lug" of the inlet connection?

 

For installation, do i spin the top on and then clock the inlet fitting to the lines and then torque to spec?

 

thanks guys!

Got any pictures to show which filter canister you are working on?  The hex head should be removable, but if it's binding up during removal, there might be another problem that needs to be looked at a little closer.  As with any banjo-type fitting, gaskets are required to avoid any metal-to-metal contact.
