I wanted to see how many times the end of the poorly designed dipstick broke. It's lead ( or nonmetallic ) and doesn't take alot of pressure to come off and fall into the oil pan. We noticed it was catching on something and turned out to be a burr at the bottom of the tube. We spent awhile trying to get it out of the pan ( flushing with lots of oil, etc ) Is it possible for that to get sucked up into the motor? How fine is the pick up screen? Anybody come across this?
