I have a serious concern I had a very nice running 6.2 c code engine and i mean so nice I have no desire to even put a turbo on it. I found a crack in the intake manifold and the egr was not working properly so i have installed a j code non egr intake my question is this an ok swap It would seem so but I read an artical about removing the egr from these engines that has me concerned I have not yet started the engine but plan to have it running soon is it ok to eliminate the egr on c code heads I was told this morning its not advisable but my local sources stink unless its a cummins.
