Help. I can't remove the guide pin from my upper timing chain cover/left hand chain rail (see photos). Does anyone know where can I get a tool or the correct size and strength bolt? Dealers I called have to special order the MB tool. I tried bolts I had that don't match any size at the hardware store but sort of fit--they went in about 1/4 inch. (I also tried an M6-10 and it goes in about 1-2 turns. M5 is too small. I'm guessing I need 5.5 in 10 pitch, if there such a thing). I jury rigged a puller from a u-bolt (go ahead and laugh), but both bolts failed by stretching. I wonder if a PO over-jammed the pin into the head.
