    just purchased a 1932 model 54 Pierce Arrow convertible  engine idles very smoothly but once when one revs it to about 1500 to 2000rpm no load  engine makes  loud clatter,  restoration company  (used by prior owner )  set the tappets but said some of the followers didn’t rotate properly . and flats \ grooves in them are causing noise       does this sound correct ? if so where is a good source for the tappet blocks ?          Another source told me the 1932 model 54 had hydraulic lifters    any input is welcome

    Hi Bruce,

    1932 Pierces did not have hydraulic lifters. 1933 was the first year.

    Clatter could come from several sources.  High pitch – piston pins, medium pitch – lifter clearance, low pitch – rods, etc.

    Cheers,

    Bob
