Questions & Answers
L-134 engine developed clacking noise. Suspect piston skirt. Also suspect original pistons were cast iron. Assume replacement pistons are aluminum. Are piston pins press fit or retained by snap rings? Best regards & thanks -
Willys Jeep Parts Tech:
They are aluminum and have a clip to hold in the pin.
