2 times to the shop to have head gaskets done. Both times resulted in oil antifreeze mixture occurring. Heads were planed, and valves had 5 angle grind done. Shop said block looked great, and so proceeded to reassemble. I'm over this engine. My temper is telling me to ditch this engine completely, and install another. So in looking around I found a 1994 Lincoln Mark VIII DOHC engine, complete with harnesses and computer. It's an aluminium teksid, but I've got the SOHC Windsor. What obstacles lay before me?

 

What year is your truck, and what engine is in it now?
