M5x BMW Valve Spring Compressor
It is time to ditch that bulky universal valve spring compressor and move on to something made for our BMWs. This little tool completely replaces the large valve spring compressors we are all used to. Made specifically for the M5x engine (M50, S50, M52, S52), these custom made tools are made from laser cut stainless steel, an aluminum compression block and include a large M8 hex head bolt.
Simply install over the valve tray bolts and tighten the hex bolt. This will easily compress the valve spring to remove the spring keepers. A simple yet elegant solution, that will make you wonder what you have been doing your whole life.
If you are trying to remove the valves without removing the cylinder head, compressed air must be injected into the cylinder to hold valves up while valve springs are being removed.
