Jacko 2157 Report post Posted June 28, 2020 Anyone know for sure if the early cam ledge seals were a recall item, or if it was just fixed under warranty when they failed? Looking into replacing them when doing an N52B30 rebuild later in the year, kinda confusing what the actual state of play is with the metal Vs teflon change over point, and if the box that supports the intake cam changed at the same time. Looking at realoem, the parts catalog, its all identical on N52s between 2004-2011... which doesnt make a whole lot of sense. Or was it as simple as the metal rings being totally killed off by the teflon units? 1 Quote Share this post Link to post Share on other sites
Gaz 1061 Report post Posted June 28, 2020 Don't think there was ever a recall on them. Telfon rings have replaced metal ones as far as I know don't think we ever put metal ones back in 1 Quote Share this post Link to post Share on other sites

I have nothing in the service history, so wonder if mine has the metal rings or not (not that its ever thrown an oil pressure/vanos issue) and I have the full service history.

Gaz 1061 Report post Posted June 29, 2020 Only if they were done under warranty. Dealers who have done work before may have it still if you don't have receipts Quote Share this post Link to post Share on other sites
