[Healeys] BJ8 Large oil consumption

[Oudesluys]

Clean your engine thoroughly, so you can notice where the oil is coming 
from on a short trip, or even running the engine stationary. Also make 
sure your crankcase ventilation (whatever system is fitted) is not 
blocked. Most common external leaks are:
front crankshaft seal
rear crankshaft seal
crank case ventilation blocked, resulting in oil being blown past the seals
rocker cover (distortion or gasket; sealing of nuts)
external oil pipes and their connections
distributor housing
sump (distortion or gasket, sometimes pin holed because of dents)

Sealing the diff and rear axle is straight forward enough, see WSM. 
However smell the leaked oil first to see if the oil is EP oil from the 
diff or engine oil sprayed from the engine.
