really? obviously I'd get a lot more life out of a newer 3L than rehashing my 2.5L, but I'm just concerned with the labor. I've replaced a few of the major components in the car (clutch, AC system), and the motor still seems to run just fine. so "under $300" for hoses, fluids, filters, etc. whatever, to $1000-1500 for a 3L plus labor seems a bit higher. I will admit this engine is tired at 170k but I also know I wont be able to actually replace the tour for quite some time. this summer, my paychecks are pretty much going to go to getting my car good'n healthy again, so in your well respected opinion Demon, what's the best option?

at this point, my car is parked due to both up and downstream O2 sensors being shot, so at this point I'm looking in the future, as in the next few months.

btw, I've been reading about the O2 sensors, and I have indeed pulled codes saying upstream and downstream are both giving me issues. My car keeps stalling out and not turning back on, and we seem to think it's the sensors making it run too rich, cause if you let it sit a while it'll come back on. it drives fine, but totaling around $350 for all four sensors to be replaced, should I just replace the upstreams? I did get a code for downstreams, but I'm not sure if it's necessary. the only other code I got was the EGR valve, which I plan to clean/replace while I'm at the O2 sensors (should I clean it or replace it?)

man, that's a lot of questions...sorry guys, just want my tour back up and running healthy again.
