Plastigauge works just fine when its use correctly. Just make sure you follow the instructions. If you have a repair manual it should have the specs. Which bb is it?

.003 is a safe measurement. I've gone as tight as .0025 on my race engines with lightweight oil but wouldn't recommend it on the street.
