On the pre-serp engines the pipes for the cabin heater run from the back of the timing cover to the heater, then back to the water pump. (or vice versa - not 100% on flow direction).

How is the cabin heater plumbed in on the serpentine engines?

Looks like the timing cover on my engine has suffered from the metal debris (see earlier 'engine knock' thread) in the oil pump housing - which would require replacement. Might consider going for the crank driven oil pump if I am going to have to replace this too.

The serpentine kit has a different inlet manifold too, the heater is fed from the O/S side of the manifold and returns to a T in the lower rad pipe.
