I have not installed a set of stem seals since the mid seventies.
It was on a small block chevy. I would like to see a picture of the tool which you used to compress the springs. I also changed a spring on a toyoto ( that I borrowed from a friend at the wrong time). Had to make the tool on that one too. I just traded a 240D for this 380SE and had nightmares the first night after the trade. Perhaps you can help me along by sharing what you know about the 126 380 series.
