[Healeys] BN2 peeing oil - SOLVED

[Bob Spidell]

I finally got a chance to get under the car while it was running (I have 
a grease pit). At first, it appeared--as suggested by many--that the 
leak came from the tachometer take-off as it had oil on it. Then, I 
looked about and saw it spurting from the tappet cover just behind the 
tach that had a bolt either missing or sheered-off (the second-most 
suggested solution).

I believe these bolts are Whitworth; can anyone confirm? 1/4", about 
3/4" long?

Thanks for the help,
Bob
