Help, ignition upgrade 1982 BMW 733i

[Jonasrach]

Can someone tell me what the ignition upgrade was on a 1982 BMW 733i. My distributor cap was damaged and the ones that are available will not work on my car. Mine takes a slip on type of rotor not the bolt on type. The slip ons are available but not the caps.

first of all, use your VIN and check for the p/n in the ETK http://bmwfans.info/

and I found this thread:quote Looking For Bolt-On Distributor Rotor Adaptor
I’am Looking For a Bolt-On Distributor Rotor “Adaptor” To Convert My Push-On Rotor To The Upgraded Bolt-On Rotor For My 1983 633 CSI BMW. BMW Had a Service Campaign Back In The 80’s For Dealers To Perform This Upgrade To The Distributors On These Engines. In The Later Cars This Upgrade Was Done At The Factory. What I’am Looking For Is The Rotor “Adaptor” Not The Bolt-On Rotor Itself. Here Is a Picture Of The Adaptor’s. The Adaptor On The Left Is The Stock Adaptor For The Push-On Rotor. The Adaptor On The Right Is The Upgraded Bolt-On Rotor Adaptor That I’am Looking For And Must Look Exactly Like What Is Pictured.
