1904 Curved Dash Oldsmobile Type 6c - Making Adjustable Valves 

It is difficult to adjust the valve clearance of our Oldsmobile Curved Dashboard, as a solution we manufacture new threaded spring retainers and in turn we thread the stem of the intake and exhaust valves. As a result we can now adjust the gap to the desired size.
We use the same modern anti-magnetic stainless steel valves that the CDO had since it was restored and the spring retainers were hardened.
