I have done quite a bit of auto repair & maintenance work, but this is
my first valve cover gasket replacement. The car is a 1994 Camry with
the 4 cylinder engine.

I was told to apply sealant to the valve cover side of the gasket only,
is this correct? Also, can someone tell me what the torque setting
should be for tightening the cover bolts back down? I do not have a shop
manual for this car, this is a favor for a friend. I can go look at a
Chilton's manual if I have to, but I was hoping that someone here has
the torque numbers handy.

Any other advice or tips that may be helpful would be appreciated.

Thanks in advance!

Toyota FIPG (form in place gasket) goes at only four points on the
valve cover gasket. If you substitute sealant for aftermarket do not
use standard RTV silicone - the acetic acid released during cure can
harm the oxygen sensor - entering through the port open to atmosphere.
I think there's a blue derivative silicone seal safe for O2 sensors,
but the factory FIPG material is very good. In addition to using it for
the oil pan gasket (its intended application), also used it to repair a
leak in the coolant recovery tank (after a factory replacement would
lose its plastic cap when heated.)
Actually, sealant is applied to the head, on either side of the cams
where the round part meets the flat.
No other application of sealant is required.
The nuts on the spark plug tubes hold the valve cover in place.
30mm and 17 ft. lbs. is correct.
