[Healeys] It's not the starter

Thank you to all who replied.


It remains a mystery. I had an AH owning mechanic here today to trying a
work out what's happening with the engine of the BN3.


Plugs are out as is the starter. By putting a mark on the harmonic balancer
and the use of a large screwdriver we found out that the engine will turn a
quarter turn and back the other way a quarter turn before it stops solid.


So it will be a process of elimination starting with an endoscope in a few
days. The radiator has been removed (no mean feat as it comes out via the
grille opening) to gain access to the crankshaft nut and timing cover.


Will keep you informed.

A problem to consider.


Went to turn the engine over in the BN3. An early C-Series six-cylinder.
Rebuilt about five years back, but seen next to no use.


Solenoid clicks, but no movement from the engine. Must be the battery so
charged it, but no change.  Tried a brand new battery, but still no


Out comes the starter and connect it straight to the battery. Whirr away on
the floor. Perhaps the original Lucas starter is breaking down under load?


It occurs to me to try and turn the engine over by hand. Gearbox tunnels not
fitted so easy to wield a large screwdriver to leaver the flywheel, after
removing the spark plugs. It moves about six teeth of the ring gear, but no
more. It moves back the same in the other direction, but no further. Soon
lose interest in this manoeuvre. 


What's up? Why won't the engine turn over? Thinking cap on and perhaps it's
something at the top of the engine such as valve gear. Perhaps there is a
bent valve?


Any opinions out there?


Many thanks
