What else should I replace when I'm putting my rebuilt engine back in?
 

My engine's coming back in a couple of weeks from a rebuild after a blown coolant seal. Looking for advice about what else to replace while I'm putting everything back together.

So far, I'm planning on doing the clutch, motor mounts (cause they're crusty), belts, fuel pulsation dampener (or maybe doing a banjo bolt if I can find a junker fuel rail), and probably a couple of oil injectors (I marred the check valve a bit with vice grips). but I don't know what else? I'm kind of tempted to do my fuel injectors and all lines and hoses as most of these are probably 30 years old and I think they would be a pain to do later, but I don't know.

What would you all do?

Oh, you definitely want to replace all the soft lines...vacuum, fuel and coolant. Do not ignore the heater core hoses.
I'd also recommend having the injectors serviced (figure about $25 per unit) because the primaries are buried pretty deep. If money is a big issue, at least do the primaries- the secondaries are much simpler to access and can wait.
Be very careful with the OMP lines, they are very brittle by now and easily damaged.

Your engine bay will never be as easy to clean and repair as it it is with the engine out... so do whatever you can think of.

It's all pretty straightforward, just requires some time.

Yep, de-grease the bay, crossmember, frame rails, steering rack, etc...

Oil cooler lines, if you haven't already replaced them. Looks like you've got everything else covered.

I typically try to do all the coolant hoses, replace fuel lines, service injectors, and replace all vacuum lines, and all gaskets and o rings , at the time of engine rebuild to ensure I wont have to tear into it for a while.

on an NA car I don't allways service the injectors, but I would on a turbo for sure.
