valve stem seals on M103 motor
I'm soon going to be pulling my M103 open to replace the timing chain and tensioner, and while at it I am thinking of doing the valve stem seals. Motor has 153,000 on it. I've got a little adapter that I've made to inject air into the cylider to hold up the valves(using compressed air from a "scott" bottle from the firehouse) and I saw that the manual has some special tool for compressing the valve spring to remove the collets. I have an "overhead valve spring compressor" the Lisle type from another car. Will this work on the MB, or is the special tool absoulutely neccessary. Any other hints and tips on these two jobs would be greatly apprciated.
