[Healeys] BN2 Incontinence

[Bob Spidell]

OK, now I remember (I get my Healey engines mixed-up sometimes). I 
replaced the tach drive cable and it was a PITA; I think it's a good 
candidate for the leak as it seems to be coming from that area. I'm 
gonna pull the carbs and manifolds and install your PCV kit after I get 
the grill back in the BJ8 (just installed a DWM steering shaft).

Thanks,
Bob
