Deja Vu
Posted by BigKev On 2011/11/14 14:38:29
Just a followup on the tech session information I mentioned about the running changes to the 356 oil pump and how that is almost identical in concept to replacing the Packard V8 pump with the Olds pump.
Take a look at the pictures below and notice the similarities. The larger teeth valleys move more oil. Deja Vu.
It is interesting that looking through the service letters of all the "fixes" that were issues between 1940-1947 for the 356 to address noisy lifters on the 356 motors, then finally to solve the issue with a new pump HV oil pump.
Similar to what was happening in 1955-1956 with Packard releasing various fixes to address noises filters. I wonder if Packard had enough time, that they would have eventually came out with a HV pump to address the noisy lifter issue that afflicted some of the V8 motors.
(Let the slings and arrows commence)
