Re: Packard TSB 56T-20 - Low Oil Pressure

Posted by Bowman Davis On 2009/10/28 18:52:22

My 56 Pat has 41,000 (supposedly actual) miles on it so based on what I have been reading, I can expect it to disentegrate or require a major engine rebuild anyday now.
I'm sure it has some,most, or all of the factory mods talked about here, because it was built late in the 56 model year, but I don't know that for a fact because I haven't removed the oil pan,yet, but I intend to, just out of curiosity. My engine was quiet with no lifter noise at startup or after reaching normal temp. after setting for days,weeks and even months, until I had a timing issue recently, then I got lifter clatter some pinging, banging,etc, but only in the left bank, oil pressure was a steady 40# and oil pressure was good in both heads also. So I'm attributing all of the noise to timing issues and not oiling issues, at least for now.
Is there not such a thing as having too much oil pressure as well as not enough.
