popped the top off of coil
I am currently trying to work out the electrics on my car and while working on it heard a psshh noise. Went to the engine bay and the gt40 coil had
popped the seal and spewed oil everywhere. Any thoughts of why this may have happened.

Yeah it was sorted the electrics now and put my black coil back on now. The gt40 one always seemed to be running to hot right from the time I put iton
there (burnt my arm on it once while the engine was running).

Was it a GT40 or a GT40R?

Never ever heard of a coil doing that...
Maybe very old coil and the oil boiled and split the seal open???
or the coil had short circuited inside causing the coil to overhead and pop the seal...
GT40 don't use a resisitor as far as I know..
the GT40R is the resisitor type.. so with no resistor way too much current...
I know My Son always disconnects the coil when working on an engine with the ignition ON...
and they do heat up very fast with the engine NOT going..
and the points not openng and closing...

It is a gt40r coil
No resistor on it  wasn't sure what a resistor was so just put
it on anyway.
Still having dramas withe the electrics had evrything working except for low beam headlights. Fixed that got all excited, went back down to garage to
tidy evrything up as best i could and found that all I had taillights with parkers but no taillights with low beam. So all i have done is move the
problem from the front to the back.
One of those jobs where I thought how hard could it be. Maybe its time to admit defeat and put it the hands of a professional  . I understand the wiring diagram form the samba but somethings not right.

Yep, the r on GT40r stands for resistor.
So 12v constant power to the coil with no resistor.
Not surprised that it cooked.
They have a weak spot that allows the oil to vent when overheating.
Let the oil out and they're no good.

Electrics working fine now chucked the gt40r in the bin and went back to my bosch black coil. Basicaly haven't been outta the car (unless to go to
sleep) for the past 48-72 hours putting some k's on it before heading out to a few vw runs and car shows, after I replace the hand brake cable that
broke. Finding it hard to keep the old girl running but hey thats all part of the fun isn't it.
