Replacing Valve Stem Seals - 3/27/2008 7:54:17 AM    takai   Posts: 24 Joined: 9/21/2005 Status: offline My Stealth is currently sitting in my Fathers Garage in Southern Utah, needing an Overhaul.  The 3rd Cylinder is not compressing enough to ignite the Mixture, and the suggestion I've heard is that it's most likely the Valve Stem Seal in that Cylinder cracking, due to the fact of how it has slowly gotten to that point(it started out just smoking a bit after idling for too long). I'm going to be going down there in a few weeks to do a minor overhaul on the heads, and I'm just curious as to how many gaskets and whatnot I should replace while there.  My Dad recommended that if the seals are bad, the guides and Valves are probably needing to be replaced, as well.  He also mentioned that we'd need a Machinest to press the Guides in. I'm working on a bit of a time limit, I'm only going to have maybe 4 days to do this, and it's over a weekend, so finding a Machinest to do that is a bit of a stretch.  Is this true, and can anyone verify the Seals going bad easily?  Anyone who has pulled the heads for a minor overhaul having suggestions?

Or you can get older car to work on. I ended up buying 89 firebird to build and just keeping the stealth runing as a daily driver. I only went as far as replacing vaulve seals on my heads so i don't have much advice farther then that.
