Re: engine with no oil drain back tube provision?
Let me say up front that - as a registered mechanical engineer - I stand in awe of most (if not all) of Henry Ford's automotive engineering.
However, I removed the oil return pipe on my primary engine (in 1977) and my backup engine (1980) and have run them this way ever since, in daily driving - and otherwise - in Idaho, Washington and California, with no discernible degradation to engine lubrication. In fact - as iconoclastic as this may appear to other Model A owners - I think I can make a case for improved timing gear lubrication without the oil return pipe. My principal concern with this set up, based on experience with marine diesel, steam turbine and reduction gear lubrication (and land-based power generation lube oil system design) was that there might be excessive foaming. There appears to be none, although I will admit this is difficult to determine. I will - as a previous FordBarn poster stated - now go off line and wait to be squashed like a bug by others for suggesting such an unorthodox "modification".

Re: engine with no oil drain back tube provision?
That external drain tube also acts as an oil cooler.

When I have some time I'll get over there and inspect for the gas tank and assembly plant data. We're just going off of the title info and what we were told. The engine number does match the title, but we haven't lifted the body to match the frame. "Fingers crossed" Anyways here are some more pictures. How do we identify the year for sure besides the frame number? It does have the early style front frame/engine mount bolted straight to the block. Is that 28 only? I don't know it that is relevant. https://www.fordbarn.com/forum/showthread.php?t=109835

I noticed the taillight on the passenger fender, but does the rear of the body have the three D-nuts for the body mounted taillight on the driver side? Also, pull up the floormat on the driver side by the kick panel and see if it has the hole for the early left hand emergency brake. A car in the 200,000 to 250,000 serial number range would have still had that hole but it would have been covered by a block-off plate, while it's highly unlikely that hold would still be there on a real 1929 car. And this is all assuming that it's pretty well one car (with the exception of maintenance and typical parts replacement over the years) and not a car tha was cobbled together out of a bunch of parts. From what I can see it looks to be pretty much the former and not the latter. Deron |

hmm im goign to go safely asume your using modern oil which may not leave deposits and such. may have somehting to do with it (modern VS model A era oil) also roads were much bumpier of existant so maybe the bouncing foamed it up... probably tried to remove it as its more parts to machine correctly, more holes to drill and tap, harder to make the valve cover casting and having someone clean up more burrs. may have come down to purely a cost thing.

Re: engine with no oil drain back tube provision?
I've also seen Gordon Smith compressers with the outside oil line removed and blocked off.
