Re: help with a oil filter
Oil pan? That is assuming a by-pass filter.

Re: help with a oil filter
This is from the 1949-51 Mercury Manual. Block is the same as the 8BA.

Re: help with a oil filter
Here's a photo of the two oil line holes in the 8BA block. here's video showing complete system.

Re: help with a oil filter
Here are a couple of clearer drawings. The one with the color shows the oil main line connections as a fairly large red trapezoid near the side of the oil pump shaft. The oil return line is the green line near the center of the block/oil pan line. The other diagrams is an add-on system that had the return to the front cover, but you can see the rear fitting with the oil pressure sender and the oil pressure line to the filter.

Re: help with a oil filter
J: When I had the factory oil filter on my 8BA it was hooked up like the the filter and oil pressure sending unit with the "TEE" fitting shown in the first (RED) photo. The green oil return line from the bottom of the filter screwed into the other threaded hole near the bellhousing. There was no return line that attached to the pan. Thanks for posting better photos.

Another system was a military setup that was also a 95% type setup. The 95% modifications depend on the additional hole and a plug of some type in the oil passage. There are three different locations that have been used for the filter return line that I am aware of: the fuel pump stand using a special drilled bolt, the front cover also using a drilled bolt and the oil pan area. Apparently some blocks had a provision in the block just above the oil pan and some oil pans had the fitting in the pan itself. Last edited by JSeery; 08-12-2015 at 11:20 PM. |

Re: help with a oil filter
The 8BA's that I've seen have the return in the block just above the pan rail.

Re: help with a oil filter
They don't!
I am not expert on EVERY 8ba block and have no idea if they all have the return line hole in the block, but do know that the return line is the easiest to setup going back into the center of the oil pan. IF the block has the return port that would be the only logical place to connect it. I have seen engines with the return connection in the oil pan itself, but don't remember the block/engine years. Was also address the implication that the two holes at the rear of the block could be used as an in and out connection point on a by-pass filter. Again, this was claimed for an 8ba block. So, did ALL 8ba engines come from the factory with the oil return provision on the lower block rail as stated by Martin and 51 MERC-CT? I have always worked with 59a (or earlier) blocks.

The answer to your question is yes all Ford and Mercury 8-BA blocks have the 1/8 inch pipe thread return hole as shown by 51 MERC -CT |

Re: help with a oil filter
JSeery: You are 100% correct. I found the threaded oil return hole.
Thanks, JIM |

So, I have the return line connected to the block as it should be and a plugged up hole in my pan - more thinking and less haste = more speed ... |
