Thread: 326 Pontiac Eating the Dipstick

Tweet

My buddy has a '66 Lemans, 326 2bbl, all original and cherry, runs great. He did just take it to a private mechanic to re-seal the engine and tune it up. He did replace the oil pan gasket and rear main seal I'm told.

'All the sudden' it seems it is eating his oil dipstick.

Anybody know what this is about? I told him to put a shorter one in for cruising and leave a new one in the trunk for checking the oil.

Many Thanks, Kitz

Conceivable that the mechanic removed or loosened the lower dipstick
tube (the one inside the pan) and now the end of the diipstick flops around from the agitation and vibration
and contacts the crank. Lots of folks leave out the lower tube and have the same problem...although I dont know if a 326 specifically does.

If your dipstick flops, you're in trouble!
