What's the size and pitch of the holes in the block for the oil bypass lines? It's looking like whom ever owned my M ahead of me installed an aftermarket remote filter. One that doesn't look like a spinoff, well any I've seen anyways.

Any info would be appreciated

The threaded ports in the engine block oil galley are 1/8" NPT threads

Thank you, time to start getting parts to redo the lines to the filter adapter. It's running a PH8A right now, I think I'll stick to it.

PH8A is a Fram filter #. That is the biggest junk in filters that exist. I would certainly source a different filter brand such as WIX or BALDWIN.

I'll look into those. Would I need to convert back to the stock type filter arrangement?

EDIT:

A quick look on Summit Racing I found a Wix filter with the same threads as the PH8A for the same applications (Ford V8 pushrods)

PH8A is the Fram number but you can get a cross reference at any parts store. That is a very popular and available filter almost anywhere, even at Wally World.

It will be an easy cross reference. Keep in mind most retailers now offer 2 or more lines of differing quality filters. Example, NAPA offers a NAPA Gold line which are the better filters. They also offer a SILVER line which is the cheap stuff. I'd stay with the Gold line.

Oreily's carries the Wix 51515 which is cheaper than the race one listed on Summit Racing. When I got it, it had a Mobil One equivalent of unknown age.

I just need to get the drain plugs in so I can drill out the odd ball pan plug (star pattern) and replace it.

Drain plug sounds like an original, a 1/2" drive ratchet fits the star pattern. That is unless you really have something weird.

I'll double check that with my breaker bar. My largest star wont hit it though, I need to see what size that was.

You just put the 1/2" drive portion of the ratchet into the star shape of the drain plug, no bit or adaptor involved.

Yep,that worked. I still needed a drain plug though, because the one for the bellhousing is missing.

The drain plug in the bell housing is standard NPT for thread pitch. You could pick up one with your choice of head style from the local hardware store.

I think the ones I have coming with the water pump are 7/8 head's. I just glad to have new oil in it, helped with overheating a tad. A new water pump and thermostat should round out the deal.

There is no plug used in the flywheel housing; except during fording, that hole should be wide open.
