Thanks Streetrod, There are currently 156000 kms. Wasn't planning on replacing all of the camshaft components, no, however that all depends on this surprise? I'm guessing its one of the nasty variety? Yes it does have a balance shaft The manifold gaskets havnt ever to my knowledge and I highly doubt it. I will be sure to add it to the order list. Will be sure to get my hands on the OTC kit as well as the crankshaft holding tool to try make the job easier and smoother. Have spoken to Ford about the parts, came in at over $1700 and they can't actually confirm its the upgraded slides ect. I then grabbed the part numbers off them for a number of parts and looked online and they did marry up with the explorer parts so an aftermarket kit will definitely be the way to go. As I said im in the phase of trying to get everything i could possibly need to get for the job so that we can have a solid crack at finishing it off in the 4 days. Greatly appreciate the help!
