Hi,

I've been looking through the threads, but cant actually find an answer.

My 8BA has no filter. I wandering if fitting the original bypass filter is as simple as buying one and installing it. Do I need to drill and tap the case somewhere....where do the take-off and return lines go?
is there anything else I need?

Thanks.

All the supply and return ports are in the block.
The only major difference is how the canister assy. is mounted to the head.
Early ( prior to 1950 ) 8BA's mounted using head bolts. The later ones had dedicated bosses cast into the heads.
The oil return hole is tapped into the side of the block, above the pan rail.

^^ Not sure about the return. There may be a port in the side of the oil pan, or as part of the dipstick tube mounting. It isn't too hard to adapt to an existing bolt hole though.

I think "51 MERC-CT" is correct for the 8BA series anyway. It's the earlier engines that use banjo bolts on the timing cover, dipstick bosses and such. Ya' know, I don't think I've ever seen a complete 8BA without an oil filter. Was there such a thing from the factory?

I purchased a full flow kit from Hot Rod and Custom Supply (no longer around) about eleven years ago. The kit was also available from Motor City Flathead, PN MCF-90-OFK and it came with a short Melling type oil pump, screw-on filter bracket and hoses. A hose runs off of the pump through the side of the pan, through the filter and back into the engine at the filter feed location you noted.
Has always worked great. Originally I found the info in Chapter 9 of Frank Oddo's book, "Ford Flathead V-8 Builders Handbook 1932-1953".
Glad I took this step. Chap

I'll say it again : given the pampered use most of our cars receive, a stock bypass system is probably better than a full flow system on these engines. It filters out finer particles than a full flow system, and with annual oil and filter changes, the oil should stay extremely clean.

If you're off-roading or doing some serious racing, feel free to discard this advice.

I agree with this advice.

On a 8ba you can also drill and tap tbe fuel pump stand for the return. Helps lube the fuel pump pushrod and cam lobe. I had a coupe motors that ran fine but the lobe was worn off for the fuel pump .
