Reusable seals/gaskets

[DBL.DWN]

I’m putting together a vvt5.7 test engine together (preferably on the cheap). My guess is it has ~100k miles in it.
What gaskets/seals are reusable?

Cosmetic head gaskets are. They're pricey but have a very good reputation.

Definitely the valve cover, front timing cover, intake manifold / TB along with any other silicon / rubber-based units.

ChoohG; FWIW, a few years back, I helped a local with head R&R where the head supplier had used valve seals that failed almost immediately. With ~200Km on the clock, the end-user elected to reuse the Cometics. I didn't support this idea (good thing). Unfortunately, there was leak to the coolant passages...

Thanks. Thats what i was thinking. How about the oil pan/windage tray?

Sure; the edge of the windage tray is rubberized so should still be pliable / compressible. To augment sealing integrity, apply a thin bead (1/16") of a quality gasket sealer both sides (on this interface only).
