Engine rebuild - tips and suggestions

Hi people,

I've more or less got the engine out of my parts car and am planning to rebuild it and put it in my car which I'm going to do a lot of work on when my garage is free.

I got the engine running when I got the parts car (it had a dead DME). All sounded OK with no worrying noises or anything immediately obvious, but I didn't run it for long. At that time I didn't have a compression tester, and I've since taken the intake off and stripped the car so I can't get it running to test the compression.

The car has 118k miles on it, and had sat for about a year I think before I got it. When I drained the oil it looked OK, with no obvious sign of coolant in it. Similarly, when I drained the coolant there was no sign of oil.

My question is really what would people recommend I do when rebuilding the engine. I'm not after huge power gains (though any obvious easy improvements would be good), just want to do what's needed to make a good solid engine I don't need to worry about. I'm planning on giving it a good clean, polish the intake manifold and paint the cam tower as well for some engine bay bling.

My list of things to do so far is:
* Belts and rollers
* Rod bearings
* Valve stem seals and lap valves
* Head, intake and exhaust gaskets
* Rear main seal
* Piston rings (are these a good idea in all circumstances, or just if they have too much clearance?)
* clean all grounds, replace charging and starting wires, and add an additional ground
* Use the best motor mounts or replace if can't find 2 in spec
* Cap, rotor, and spark plug wires

Any thoughts? Particularly from those of you who've rebuilt one of these engines. I guess it'll become clearer what needs doing once I start getting it apart.

Mike
