I’ve worked on and rebuilt many diesels engines over the last few years and learned my lesson with the isx, have someone who’s done them a few times do it it saves alot of anguish imo lol
I know this is an old video but there is a TSB on that large cam retaining plate. How do I know....because I just took my front cover off and it was in 3 pieces and had filed a little bit of the crank tone ring.
