The 4-cylinder 1968-69 Porsche 912 Aluminium Distributor

The Bosch 0231.115.061 ignition distributor is used in the Porsche 912 model 912. It uses Vacuum in conjunction with a mechanical advance curve to create a good advance curve that always comes back to idle.

The Advantages of Vacuum Advance

The 0231.115.061 has got a bad reputation as a distributor. This is because the vacuum advanced distributor is associated with the smog controls. Used on the 1968-69 Porsche 912, the smog controls pump air to get a better burn, and therefore cleaner at the tailpipe. The smog pump can take up to 8 horse-power from the engine and that is a lot in a 100 or so Horse-power engine.

The advantages of using a vacuum module for the ignition curve is faster acceleration and a better return to idle. The vacuum signal comes from the spacers under the carburetors. You may have seen metal spacers with a small 1/8th” pipe coming from the side. We have seen many 912’s with incorrect distributors. Maybe it is because of the age of the 912’s. Or the fact they used to be a reasonable price, but whatever the cause many 912’s end up with the incorrect distributor.

Rebulding the 0231.115.061

There are not any major issues when you rebuild a 0231.115.061 distributor. The aluminum body needs a good clean and polish once all the parts have been removed. The normal problems from using incorrect parts like springs can occur and if you have a broken vacuum module, there are no new ones available at the time of writing this report. Your only choice is to find a functional used module, and that may mean buying a complete used distributor.
