sam1904 Posted December 30, 2020 Share Posted December 30, 2020 Just curious.... Just noticed these yellow and red paint rings on my cam and could not find anything on the Google or forums... What do they mean, does it mean aftermarket or are they factory marks? Many thanks! Sam Quote Link to comment Share on other sites More sharing options...
Preyupy Posted December 31, 2020 Share Posted December 31, 2020 Never seen markings like that. I suspect that someone in the last 45 years put them there. Possibly a “reground cam?” Not a BMW marking Quote Link to comment Share on other sites More sharing options...
Son of Marty Posted December 31, 2020 Share Posted December 31, 2020 Not factory although I have seen one marked just like that before but never could decipher the code or manufacturer but defiantly a regrind. Quote Link to comment Share on other sites More sharing options...
Geoff Raynak Posted December 31, 2020 Share Posted December 31, 2020 assuming it is white and red ... maybe it is a 92Ω resistor? or maybe 29Ω 1 2 Quote Link to comment Share on other sites More sharing options...
