What to replace when installing a used engine?

[Ex-User (107751)]

I'm about to order a used engine for my 172,
What should I replace before installing it ?
My current list is:

Timing&Aux kit,
Dephaser pulley (Mine is bad, The new one is unknown..)
Water pump
Camshafts & VVT solenoid seals kit
Sump gasket
Crankshaft seal (gearbox side)

Anything else to look for ? Oil pump, any seals I might be missing...

Reseal rocker cover
New spark plugs
Oil and filter

I wouldnt touch rear main seal unless you got the fittin tool, only my opinion mate

New clutch

Rocker cover should be cheap and easy to reseal on the car if needed I guess? So no point doing it with engine out
Is the fitting tool for the crankshaft seal really that important? Should every garage have that ?

Rocker cover holds the camshafts in so its a big job to reseal

Yep, if the crank seal isn't leaking, leave it as it is.

New clutch, 100%.

Likewise with the sump gasket. If it's not leaking, leave it be.

Easy enough to swap with the engine in place.

I won't know what's leaking unfortunately as the engine will probably be washed before I see it

Clutch for sure.
