Well, I just changed over the title, got my new licence plates and added my recently aquired '71 240z to my insurance policy.  I was ready to start driving!  Unfortunately, it turns out todays simple oil change revealed approximately a 50/50 split between oil and coolent draining out the crankcase....not what I wanted to hear from my mechanic  .  After some serious contemplation about reverting to British sprorts cars, I have decided to go ahead with the repair.  So, everyone check between the cushions of the sofa and send me your spare change!  Seriously, anything I should know while this thing is opened up?  Thanks!
