Ask away, happy to answer
I have one spot where the rust is showing up badly: passenger side rocker panel at the bottom of the rear/passenger door right before the wheel. I filled it up with some bondo and will have to do it every year to slow down the rust. When I opened up the front cover on the old engine originally thinking that the noise was coming from the phasers, I found that all the components were in good shape, the guides were still intact. The tensioners were weak and there was some slack in chains but that was at 200-205 k so it was expected. Otherwise, the old engine was still in time and I could easily get another 50k out of it if not more. That's why I am keeping it as a spare when the "new" one that has 150k on it already goes bad. The transmission is still original which is amazing considering that I pull trailer of all kinds and plow my driveway and neighbors with a light Fisher. Few years ago my transmission control module TCM was throwing "no communication" errors and Ford dealer diagnosed it that I need a new mechatronic (valve body) assembly. They wanted about 2500 for that. I bought a rebuilt one online for 500, replaced at home, and the errors kept coming back. After searching more online, I found out that bad coils will disturb the signal between PCM and TCM and throw that 900 code. I installed new Motorcraft coils and the problem was gone and never came back. So the tranny is still original save for the valve body which was also good, but replaced for no good reason (again - misdiagnosis as with the engine).
