[quote=proturf;1547841]I have only had my 7.3 IDI for a couple of months but the first thing I did when I got it was to add supplemental coolantant additive (SCA). This is my first diesel truck but I have had diesel equipment and I know about pinholing/pitting from sleeved diesel engines. This is due to cavitation in the cooling system and you need the additive to prevent it's occurence. I use the Cummins brand (Fleetguard) DCA4. For more info/discussion.... you can go to this link.
the 6.9 and 7.3 arent sleeved engines--walls are cast as block--------non-replacable except by boring and putting a sleeve in---dry--not wet------
