bbigrig Posted September 12, 2013 Share Posted September 12, 2013 So lets see here.......952,000kms. My 2008 Pinnacle with an MP8 485 is now into its 3rd set of Stainless (connicle) injector cups.The usual loss of prime and hard starting is the first sign. No miss, ran ok but you could hear that MP lost some of her punch. She also had a rich burning fuel smell at the exhaust.( which only started a few days before we took it in as our shop is swamped right now)1st set, approx. 500,000kms (switched from copper to stainless under Warranty)2nd set 720,000kms the dealer only replaced 3 cups. (Cheap warranty buggers!)3rd set I told the dealer to replace all 6. (At my cost this round)Turns out 2 of the injectors were as they now call it, "Fretted" (cracks in the injector tip body)So 2 injectors, 6 cups and almost 4G's later its back on the road. This truck has been good to us for the most part. Hope these cups don't become a regular every 200,000km thing. Quote Link to comment Share on other sites More sharing options...
