Antifreeze leaking from rear of engine 1987 Allante
When engine is warmed up anti freeze leak s from back and driver side of oil pan. I am told it may be coming
from the expansion (Freeze ) plug on the back (firewall side) of the engine, then collecting on the lip of the oil pan and dripping off in 3 or 4 places. After I stop driving it continues to drip about 2 ounces of fluid; it
drips while the car is being driven too.
The car has 142,000 miles. At c. 100,000 mi. I had the dealership remove the engine and replace all 'seals',
Mechanic says I would have to drop the transmission to get at the 'freeze plugs' which is about 9=10 hours' Could it be anything else?

If I remember correctly there is a pipe with a short connector hose running around the back of the engine.
Look at the number 0ne in the first image just after it rounds the corner there was a short piece of heater hose.
Also those metal pipes rust out..
