Is it worth keeping?

[drrhein]

I've decided to keep it and fix everything reasonably practical.
So repairs are progressing.
Timing belt was not slipped and in not bad shape for 110,000 miles.
Bad news I DO have the exhaust manifold crack in #4, I need a new one anyway because I rounded the oxygen sensor trying to get it out.
I've never seen one this tight, I used special tool, heat. PB blaster, no luck so out comes the manifold. Now I just have to find one. (long one)
Crank and cam seals are NOT leaking, so I'm debating changing them.
The crank pulley is properly torqued and OK.
Used IAC came in and works properly. I'll set duty cycle when I get it all running again.

Found MORE disconnected vacuum lines and a bad EVAP solenoid.
Water pump shaft has quite a bit of play although, oddly, not leaking, I'm changing it anyway with a proper Suzuki pump due to it's location (I'd rather pay$40 extra to not have to replace it in a year)

I didn't check ignition timing bc I'm pulling distributor anyway to change O-ring, I'll time after.

I suppose that while the top is off to change manifold I'll go ahead and do valve lash.

Any suggestions while I have the top and front off?
