The same goes for people who go to an 8 volt battery rather than figure out and properly fix their electrical problems on a 6 volt car. I know I am going to get some pushback on this, but I feel that if you have a properly restored original 6 volt car, there is no reason to update to 12 volts. Of course, if you have a "resto-rod" with modern accessories, then a 12 volt conversion is a must. I have a '54 Ford Convertible with factory power windows and power seat, and the windows and seat adjust faster on 6 volts then those in my modern Lincoln. That is because when I did a frame off restoration on this car I installed all new wiring harnesses and the car has a properly functioning electrical system. Back to the original "oiling" subject, the engines in my cars have all been rebuilt and run with modern detergent oil for the past 40 years and I have never had an upper engine oiling problem.

Thanks Ted for the excellent explanation and putting this in proper perspective. Ted (9/4/2026)
Kultulz’s pictures are perfect examples of two different engines with the added overhead oilers. If that top end issue was as prevalent as the link to the video would lead you to believe, pictures of those overhead oilers would have been readily available to insert within that video. While not knowing the exact number of the millions of those Y engines that were manufactured over the years, the percentage requiring overhead oilers was extremely low and most of those were attributed to poor maintenance and service intervals and not necessarily to a design issue. Undoubtedly that percentage is significantly lower than the 4% defect rate that GM is currently comfortable with having during the last five years of crankshaft issues in the LS engines which truly is a manufacturing/design issue.
I do still get the random core FYB engine that has overhead oilers installed on it. I find that a majority of those added oil lines are only on one side of the engine and not both. Delving deeper into these engines (which have been previously rebuilt), I find the center cam bearing incorrectly installed with only two of the three bearing holes being properly aligned in the block. Depending upon the clocking of the bearing, one of the upper oil holes in the center cam hole is not aligned with the appropriate hole in the bearing which makes it a 50/50 chance on which bank is getting or not getting its required oil.
