3.0 Montero Engine swap
 

I looked through the threads and didn't find the answer so I am going to ask it. I have a 1989 Motero Sport. The 3.0 in it will not start as the fuel in the tank got rusty and has sat for about 2 years now since it last ran. I question how good the engine is at this point and so am leaning toward a swap. I know I can use other 3.0's from Mitsubishi and other manufacturers 3.0s. But if I go to another models 3.0 will I still be able to use my same electronics, ie PCM. Same question if I go to a 3.5 or another engine?

Of course. New fuel lines, fuel pump, filters, gas tank cleaned out professionally... everything redone.

I hesitate to think the engine is still going to last much longer even if it does start because it will crank but not start. So when tried to startit 2 yeata ago I just moved that crappy gas into the engine. I expect its been pretty unfriendly to the cylinders and seals.

When it did run, about 3 months before I last tried and then discovered the orange gasoline in the tank, it smoked and burnt oil pretty decent. I will likely rebuild the engine in a few years if I get a replacement or sooner if I cant. But the quote I got to rebuild will be a few grand to be done fully and right.

My wife's not real keen on me fixing this thing up but I have a sentimental attachment to it since it was my first vehicle and I really don't want a new vehicle with all the electronics and expensive repairs.

Thanks for telling me you won't answer my question until after you question my intelligence and then you don't even bother helping me with an answer. Thanks for pretty much nothing.
