Locking Small Block Dip Stick

on some engines extended operation at high RPM can cause oil/pressure to push the dipsticks up or out completely, even with proper venting.

my solution was to braze a small washer to the tube and drill a hole in the handle loop to install a small spring. with a small rubber o-ring on the stick it was snug and did not leak.

certainly not as trick, but it worked.
