My 1st gen 3.0 Montero LWB is now blowing white smoke like crazy so I am either going to rebuild or swap to a different motor. I would love to go diesel but after much research think it's going to be a major PITA & a lot of $$$. My other choice is a 4.3 (tons of cheap Blazers on CL). I have done a lot of searching & can't find much info on doing the 4.3 swap. Is it worth it or should I just rebuild the 3.0? This vehicle will be used for my family expo vehicle & DD. Any advice will be much appreciated.
