Re: Stubborn Tight 2-Piece Valve Guide Won't Come Out
When someone is paying us to disassemble an engine for rebuild, wasting time on removing a stubborn guide is not prudent. Our method is to raise the valve until the mushroomed end is against the guide. Use a cut-off tool to cut the stem and remove the head of the valve. Grind the end that was just cut to remove any burs and also chamfer the end. Drive the remaining portion of the valve stem thru the guide and out through the lifter bore. Use a Air Riveter gun or a large Air Hammer and rattle on top of the guide halves. They generally will either come right out, -or shatter where the pieces of the guide will come out.
