I wonder how many folks have torque wrenches that measure in inch pounds. I found one at a yard sale for $5 20 years ago. You can almost over torque 28 inch pounds with a nut driver.

Don't forget to check the torque after a few miles of driving. I always do it after I use a tank of gas.

I have one with a calibration sticker. What do I win?

You just won a non over torqued valve valve cover bolt with the bolt head still intact. Could you post a picture of the calibration sticker?
