I get a puff of smoke on start up on my '85 with just under 50K, and it seems to be the result of valve seals drying out (as explained by forumites). If I use 'high-mileage' oil, do you believe that it may solve this problem? If it does, what happens if I go back to what I am now using, which is Wal-Mart Synthetic? Or should I keep using it? This engine does not require Synthetic, so Wally Syn, should be better than normal dino, (that's my theory anyhow-now you could laugh). thanks
