Good evening all,
after setting up for 5 months while I was overseas, I started my '88 911 with 82K miles and it produced heavy exhaust smoke. I let it run for a couple of minutes and didn't see much of a decrease so I shut it down. I've never let it set up this long before and I'm not sure if this is normal. If this is normal should just let it burn off? Any comments would be graciously welcomed.
