Exhaust manifold. Often sounds worse when the car has done a hot run,
sat for a while, and been restarted.
Cars will run for _ever_ with exhaust manifold ticks. The only
possible (but extremely rare) problem is that the tick is coming not
from the block/manifold union, but from a crack in the outer part of
the manifold and hot gases are playing on something delicate. Very
rare, though.
