Replace these while engine is out or waste of money?

[plymouthcolt]

I will have to drop my engine soon to replace the clutch.

Waynes 101 book suggest some "while it's out" part replacement and I would like some opinions.

(My engine is dry and doesn't leak a drop.)

-Oil pressure switch
-Thermostat O-ring
-Oil breather hoses
-Oil cooler seals
-Pulley seal
-Breather cover gasket

How many miles on her? Vacum hoses are very easy to get to and cheap. Dry rot from age?

I just put a clutch in my 87 carrera. I did put seals in front and rear tranny. Seals in the drive axles. Also, replaced the seals in the engine front and rear. You have to pull the metal shroud to get to the front seal, but you don't have to worry about engine leaks. 126k miles. There Is No Substitute!!!

I would think that these three are on the "must do" list. IIRC the oil cooler seals can be done (but difficult) with the engine in. The hoses if they are worn (I reused mine). I didn't do the pulley seal.

I think the total parts cost for these are under $75 so I'd do it for peace of mind.

I'd also change the cylinder head temperature sensor if it's the old type one pin connector type. It's easier with the engine out.
