Installing Used Engine - What to Freshen Up?
I may be installing an '04 engine in my '03. The '04 has about 80k miles. I am planning to replace the following on the '04. Should anything be added or subtracted?
- plugs (+4's)
- wires (magnecors)
- front cover gasket
- oil pan gasket
- rear main seal
- front oil seal
Will I need exhaust manifold to downpipe gaskets? Is there a front tranny seal I should replace while the engine is out?

do you need an engine or just to cheap for a proper Diag. Some go bad but if thy make the 50k mark no oil troubles and you will need to do an entire reseal. Everything leaks after awhile. I do engine reseal all the time at the dealer and we put a motor in once every two years. The are trouble free unless you overheat them a few times.

@ 80k if the head gaskets were not done yet, they will need to be done soon. i would get the HG kit from atlantic british for $150 and get yourself some new bolts. also have the heads checked to see if they need to be machined. you might as well put the work in now or else you will have to take it all apart when its installed.

With regards to headgaskets, how much more difficult is a replacement in the truck versus pre-installation?

Replacing the head gaskets with the engine in the truck is two days worth of work for a good do it yourselfer, plus time lost milling the heads at a machine shop. A garage will probably want $1500 and twice that for the dealer.
Replacing the head gaskets while the engine is on a stand is probably a matter of hours, plus any machine shop time.

Mike, am I missing any critical gaskets in my list above? I searched for the tranny front seal on AB's website and couldn't find it. Any suggestions?
Mike, I'd also like your opinion on the head gasket issue given the discussion above from Dave and Hilltopper. I want to avoid doing the HG if not absolutely needed on an '04 engine with 80k miles. Am I overestimated the difficulty of doing HGs? It just seems as though a lot of people have sealing problems after doing them.
