Default Faulty Lifter?

Tick tick tick tick she goes for the first few minutes following a cold start.
Pretty much disappears afterwards, however, depending on the level of my obsessive-compulsiveness , there might some trace of ticking once warm but much attenuated.
Oil level adequate, Mobil 1 5w30, 60k miles. Lifter you think?

Any one have an exploded view of the SOHC? My Haynes manual is not very helpful in that regard.

How would you go about isolating the issue, also, is there a potential for subsequent wear/damage if left un treated?
Many thanks from cold and snowy Montreal.

REWARD EXCELLENCE!

The entire lifter system can get a bit out of whack mechanically and clank when cold. The shafts that the rockers run on can either snap come loose and you get excessive clearance. An individual lifter can become leaky and leak down overnight and then tick. You begin the isolation process by listening with a mechanical coupling (big screw driver) placed along the exhaust and intake side of the head/cam cover joint while the engine is running. Place the handle against your ear. You are attempting to identify intake/exhaust and cylinder.

Hey Old Nuc, thanks for the suggestions, your posts and opinions are held in high regard.
Would the screwdriver technique be sufficient in isolating intake versus exhaust?
It seems it should be simple enough to find the proper cylinder but could the close proximity of the I/E be as obvious?

One side will usually be a bit louder. Your mileage is really not high enough to be experiencing lifter problems.
