[Mgs] A Bad Day with the MGB engine

[riverside]

  Did you remember to prime the oil pump when installing? ( fill with oil or 
assembly lube ?STP? ) It is not unusual on these engines to take several 
minutes to get oil pressure by cranking after a rebuild if the pump was not 
primed with a thick oil that sticks to the pump gears. After the first 
minute of cranking, to keep starter damage to a minimum I crank for 15 to 20 
seconds and wait an equal amount of time between cranks.  Usually get oil 
pressure about the time I am ready to give up.
   If the oil pump was not primed, it is possible to reverse prime it 
without removing the oil pan.  This is done by disconnecting the oil line 
from the rear of the block and filling the oil passage with oil . You may 
have to refill the passage.  Then crank the engine backwards either by hand 
or put into gear and roll the car so the  engine turns backward a few 
reveloutions. The object is to get abit of oil  into the pump to wet the 
gears.  Then crank as normal. It helps to prefill the oil filter also.
   If you do the no-no and start the engine , it should get oil pressue 
within about 15 or 20 seconds. Not a suggestion and don't let it run any 
longer than that.
