How much would a rebuild be on a 3.8L cost?
I have never had it done before, and I am trying to decide to sell the 03 Mustang or to rebuild it at 150,000 miles?
If the motor is seized, take all of the spark plugs out and fill each cylinder at least half way with Marvel Mystery oil before you take it out and begin to break it down... I don't know what this stuff does exactly, but it is an amazing product! It will literally un-seize a motor. If you don't do this, all the parts will be very difficult to get out of their places.. Rebuilding an engine can be a rewarding, tiring, frustrating and educational experience... I would recommend that you go for it! If the motor is not seized, sell it!!!
you never get the right money for car's eny more and if you do it your self and you can aford some or all now part's is amazing when it's done just rember to run the enigen in for 600 mile's befor you ask for power
get a running motor from a salvage yard, cheapest wtg.
