Thanks for advice on the 47. Been gone up the North Shore for three days. Very cool for this time of year...47*
Got the parts for the mechanical oil pressure gauge. Installed it off the oil pressure cross with a "tee" to keep the sender for the dash gauge and the new mechanical gauge on the engine.
Did a test cruise yesterday (about 10 - 12 miles )
Oil pressure cold was 58 on the new gauge. On the test run the pressure on the road was about 40 as the engine warmed up. As I returned to the garage the pressure had dropped to about "0".
Went out today and did the same test cruise. Pressure cold
was 58. During the test highway driving 50 -55 mph the gauge read about low 40. Getting back to the garage it was about on the 0 peg. The mechanical gauge read about 2 lbs.
The Temp gauge was right in the middle all the time.
outside temp today about 80.
Is it time for a new oil pump for the 47 ????
I've checked some of the Packard parts dealers on line.
Seems like the oil pumps for the 356 are to get you existing pump rebuilt. Anyone had any experiences with pump rebuilders and what kind of turn around time is required. Who does a good job on the rebuilds.
Thanks to all who have responded.
