Gentelmen Does anyone know if there is a block off for the speedo drive hole if you don't want to run a speedo cable on a C4,I am guessing that the hole has to be sealed. Thanks Andy
I have never seen a block off made specifically for it, but what I used is the Electronic Sender from a later model (It fits just like the cable) and just knocked off the wire part. And YES it will pour oil if you don't seal it.
Yes the kind you tighten up and it expands I had a electro our of a later model one night it blew out oil all over the freeway, under my car pulled of at autozone bought a expandable plug been there ever since!!
