1969 Opel Gt 1.9 Automatic
Hi guys so I have been woring on the GT lately. It isn't running perfect but it's running pretty good. I know that the valves are loud and annoying in Opels but my grandpa thinks they might be too loud and we want to adjust the valves so the engine will run good(even with a vacuum leak) and so te valve noise might go down. Also who knows when the last time those valves were adjusted. It is a solid lifter engine because it is a 1969. So does anyone know how to adjust them?
