Splash lubrication question

[51Deluxe]

Ran across this statement on another car forum:

"the Chevy 6, with splash lube would burn up at sustained speeds over 55, with overdrive, you could do 65. Chevy wised up in ’54 and after that the 6 was good for extended high speed use. "


Just wondered if the Kaiser 6 is also splash lube, or if it has pressurized lubrication.

Kaiser engine by design is full pressure lubrication

Chevy 216 6 cylinders were full pressure oil feeds in 1953 Powerglides and some manual shift cars (my brother had one which is why I know this bit of trivia).
I don't believe there were any Chevys with splash lube engines and OD. Prior to 1955, Chevy cars and light trucks had torque tube rearends. Beginning with the radical new 55s and open driveshafts, Borg-Warner OD was available and was somewhat popular up to the early 60s.

And... just because an engine has full pressure oil feed does not mean everything gets good lubrication. Ford in particular had poor oiling to the rocker arms in their early OHV 6s and V8s.

Yep- as I recall, the 292 V8 was notorious for this.

  The early ford Y block had a oil passage to the rockers that would plug up. In 53 chev std trans was 216 and auto was 235.

Most of you talk like Full pressure lubrication means all parts get lubricated through pressure.   That is not the case.  There are many parts in our older cars all the way to our newer car engines that have parts lubricated by splashing.  These include but are not limited to the valves and springs, wrist pins and pistons (although some engines have a squirt hole to spray oil at the cylinder wall on the thrust side and a few have connecting rods with oil galleries that feed the wrist pins) and of course the rings.   If the oil is too thick, like straight 50 weight, the oil will not splash far enough to lubricate these part and they will wear out quickly.   Also, the oils used in the 50's and before had virtually no additives whereas modern oils have 35 - 40% of each quart comprising the additives that are necessary for the modern engine to survive and a boom for older engines to last longer.
