I was planning on replacing the valve stem seals and possibly the valve guides (if needed, by a machine shop) on my 2.8 V6 and maybe even the rings, again if needed. I was talking with someone who said that rebuilding the top end (valves and rings, right?) without also rebuilding the lower end (crank & piston arms?) would wear the engine out faster than not doing the valves & rings.

I want to put a 3.4L V6 in my Troop, but I have to save up for that. The whole reason for looking into the valves/rings is because I am using oil...


Not usre what the guy you were talking to meant by that. Not a preofessional engine rebuilder, but his comments don't follow any logic. Plus, people who say something would "wear the engine out faster" are suspect to me. That is an extremely vague way to back up a point.

To replace the rings you have to remove the rods, and replace the rod bearings. This usually requires you to pull the engine and break down the block. I think the time an effort you spend on this would be better spent on a newer 3.4 engine. You can get them around me for $400. The machine work on the valves might cost something like that anyways.
