Creaky bike...Seat post?..ideas?

I have a mid 80's raliegh technium Trilite Scott Tinley model. I recently had it rebuilt and tuned and working great. The last two rides (about 120 miles since the tune up) the bike is creaking more and more. When I got home I tugged around on the parts and it seems to be the seat post? If it is tight enough to keep the seat in place, can it be loose enough to creak? I know these frames have a bad rep for cracking, but I don't see any signs of it. Could it be my cranks as well?

Everything is riding and shifting fine, but I'm not sneaking up on anyone. Any ideas?
I am 6'4 and 230 pnds if that helps troubleshoot.

See what Sheldon Brown has to say on the matter:

Most of my creaking/noise woes have been fixed by some recommendation on that page.

I had a seatpost that creaked and one day it just stopped...It snapped off! Remove the post and check around the collar for hairline cracks. How much post is exposed?

It could be the cranks as well, they are notorious for mysterious clicking sounds.

We have a solution!

I have a great LBS. I took the bike in tonight and got the same mechanic that rebuilt it at Christmas. Basically when I bought the bike the seat post was too small. I had replaced it and had to stretch the tube opening to get the correct tube to fit. I did my best to get rid of the burrs, but apparently not. Along with not having used enough grease, one of those burrs was boring into the seat post making all of the clicking and squeaking. He didn't see any sign of cracking. He knew about the problem with Techniums, but said he also knew of tons of them being ridden forever by big guys. More importantly he said the paint will start to chip before failure.

The reason the LBS (John from"The Hub", a co-op off of Washington) is so great is that he rode it around the block twice, and quickly honed it out and greased it for me, and solved and ordered a new chainring for me. All this within 30 minutes of closing time. Amazing

That's pretty good! Stay with the LBS, a good mechanic is hard to find these days. Creaks can be really annoying to pinpoint.
