Block Teardown
As I've mentioned here and there, I've been working on a '90 13bt conversion for my car. The motor only has 30K miles on it and seems to have been kept in very good condition for being 17 years old: in the process of stripping it down to the block for a paint job, I didn't encounter a single stuck bolt, flake of rust, or stuck gasket. The exhaust manifold gasket could have been put on yesterday.
The inside of the engine looks like it could use a scrubbing though, and I have the desire to polish all the ports and runners (without any kind of actual porting). It would be a lot easier to just pull the motor apart and clean the rotors and irons directly, but I don't feel like dropping an additional $350 for a full gasket kit when I could just expend a little extra effort with a lot of SeaFoam and a very long toothbrush. My question is would the kit even be necessary? When people talk about a rebuild it's usually because a seal went bad, but when the engine was fine to begin with would the whole set need to be replaced anyway just because it was pulled apart (crushables, adherings, etc).

You would need:
4 inner, and 4 outer coolant seals
4 dowelpin o-rings
Rear stationary gear o-ring
Front cover oil passage o-ring
Front cover gasket
Front main seal
Rear main seal
Oil pick-up tube gasket
Thermopellet plug
The coolant seals, and front cover gasket will come apart when you tear the block apart. The rest should really be replaced when the block is torn down anyway. Do it once, do it right kind-of thing. If you're tearing it apart, you should really consider doing a full rebuild.

You can do the water injection trick (not to be confused with auxillary injection normally found on higher HP turbpo set-ups) to clean out most of the carbon.
Basically you suck up a little bit of water with a vacuum line while the engine is running. You can do a search for it for more info.

And by "a little bit" you meant a gallon, right?
