Crap, another No. Cal Diesel (in the making
). '97 Cali's had an injection set-up closer to the SD (Super Duty's) from '99-03. A little more power then the rest of the OBSs but with that comes the price of having some one off parts that are expensive to find and replace( I.E. the '97 Cali PCM is worth gold) '96 and '97's came with a different HPOP (that's High Pressure Oil Pump, you'll pick up acronyms quick around here) that is more desirable as the oil return is more like the SD set-up making them easier to get aftermarket. Late '94.5 and '95's have a different HPOP and front cover. Not hard
to find parts but you have to know what you need and not just buy parts willy-nilly.
Do the checks that Kris mentioned, leaks in the engine valley are kinda easily fixed and leaks under the truck are somewhat time consuming. Not really deal breakers to me. These engines have a drain hole in the back of the engine valley that drains down the back of the motor and exits either under the trans (making it look like a rear main seal leak) or over by the starter (making it look like you have a High Pressure galley plug leak. Both are usually
leaks from the turbo pedestal. Expect a $300 R&R bill to have a shop fix that. Just because it has low miles doesn't mean that it was treated nice. If you flip over the oil fill cap and the motors internal gasses blow it off the fill tube you are looking at good (as in bad) cylinder blow-by and a hefty engine repair bill. Walk away and don't look back....
Tuners like Justin above are totally willing to answer your coming power questions and please buy from our sponsors as if they don't see a reason to be here we loose their support. When making a purchase let them know you are from the ORG and I often get a price break.
Ask a question anywhere and if you feel shy about a particular question up above this thread is a newb free-to-question thread. One thing though and this _might_ be considered a warning from a Moderator. DO NOT ask "how do I make my truck smoke" like those a$$hats on YouTube. We do not support this smoking crap.
