Dan,
Others have presented good advice. A couple of thing I haven't seen mention
directly:
1. Have a machine shop do your head - deck it, new valve guides and seats,
and seat the valves.
2. Have the con rods and crank magnafluxed - checked for cracks.
3. Have the block hot tanked. You'll have to replace the freeze plugs.
4. When reassembling, turn the engine over by hand - socket on a ratchet on
the crank bolt, after every part you install. You are checking
for something
binding. If you do it as you insert each part, you'll know that
it's the last
part you installed if it does bind. I did my Volvo P1800 engine year ago,
and didn't turn it over after I had gotten all the pistons
in. So after I got the
cam in and the head on the engine was locked up. So I had to tear it down
again. Turns out that there was an end bearing that could go in 2 ways.
I put it in wrong. Took a while to find that.
5. Back the valve adjusters off before turning the engine over. The may not
be adjusted correctly and you'll bend the push rods. I did that on my TR3
engine. (The 1st engine I ever rebuilt.)
6. After fully assembled, remove the spark plugs and turn it over with the
starter to get oil pressure up before you try and start the
engine. If you
have an oil pressure gauge, watch it for pressure. If not, go buy a cheap
mechanical one and install it. Do not run the engine for long periods of
time on the starter. No more than 15 - 20 seconds. Then let it set for
5 or 10 seconds. With no plugs in, the starter can spin the
engine easily,
but you don't want burn it up.
