I bought this to do a head gasket replacement. I had no problems with slippage as long as I made sure the valve seat fork was secure before applying full torque. Also, remove your spark plugs and use a 1/4" diameter rod to go down in the cylinder and feel that the piston has traveled down before using the tool. You don't want to bend a vavle! This tool is worth the purchase!

Purchased this item and when I tried to use it, it wouldn’t clear the lobes on the camshaft. I had to grind the arms down so it would clear the lobes. Not a big deal but it was labeled fir this vehicle I had exactly.

I bought this to replace valve stem seals on a 2001 durango. Great price for a specialty tool. Worked great! Just make sure you get the foot seated up against the cam good so you don't launch your keeper across the shop!
