I have a 1996 4runner that has 230K miles, everything else is good but at first start up it runs rough then clears up, I have also starting to loose some coolant. I'm worried it could be the start of a head gasket issue or even a cracked head. Just for the fun I started looking for replacement motors and found a local 4.7 out of a 2007 4runner for $1K. Would that bolt right in or am I looking at some serious modifications?
thanks
