Well I am considering buying a Powerstroke and due to CA smog BS I need to stay '94.5-'97. When looking at a used Powerstroke what are some things to look for? Is there a "better" year within the short range I mentioned? Things to avoid? I did find a truck that already had the D60 swap up front but the owner said it had once lost nearly all oil due to hole in HPOP line--even though the engine should have shut off due to no drive oil pressure could damage have occurred? Any tips to help select a strong and reliable engine would be appreciated.
