So today since its nice out i thought i would take the 4-tec out. put new gas and plugs in and it wouldnt start. so i took the coolin head to see if it had any internal damage, so when i took the head of the piston sleeve came off with that. i supose that that is not a good thing when i can do that. Also does that mean that the motor is bad. Some one plz help me. Thnx for the help in advance.
