Hi,
Could use some help. Still pretty much a newbie to the z-car scene.
Have '75 280z that my family bought me to restore for Xmas. Anyway, have it running (sort of) well enough to drive 10-30 mile round trips. Well, the short cut to the story is that during such a length trip the car will puff smoke (fairly white, but it SMELLS LIKE OIL) briefly but intense enough that it reminds me of some of those smoke-screen tricks you see in a James Bond movie (ok, more likely Maxwell Smart TV show!). Seems to do it only when decelerating or at least not while accelerating. Weird part that I'm having trouble comprehending is that it is very intermittent--its not like I'm a rolling trail of smoke. Did the search, didn't find anything that really hit on the symptoms I'm seeing (and I've never seen such different behavior before, but then again I'm not used to diagnosing 35 yr old cars). Friend of mine suggests that it might be valve seal going bogus. Any hints or other ideas of what's my car's problem?
Thanking all of you in advance for your help!
Todd
