is it the camry alltrac? the four wheel drive version?

you could always replace your 3sfe for about $250 or you could upgrade to the 5sfe from the newer camry or n/a MR2 for about the same price. it would definately be easier and much smarter to replace the engine rather than sell it as is. after yo ureplace it, you could easily get $1500 for the car for a quick sale.
