The seller isn't specific on the smell/look of the smoke but has reason to believe it is fuel related might be a leak hitting a manifold. I've assisted in a few engine rebuilds/swaps/etc in the past so I have enough exposure to feel comfortable jumping in. That, and having a father that owned/operated a custom engine machining and import shop gives me access to enough knowledge/resources haha. My understanding is that the V-8sin these models were used heavily in the 80s and early 90s so sourcing parts shouldn't be too bad in the event I would need to. However, if it is the diesel model (which I cannot recall at the moment) that would make things a little tricker as far as access to certain parts. What modifications were you asked to do? With 25 years or older cars there's not too many hoops to jump through, unless its state specific regulations that are above and beyond. However, if you were talking under 25 years then I agree, much more rep tape especially with crash safety/emissions controls.
