Well during the last month the car has been in and out of the shop getting little stuff taken care of. I finally got the car back for a decent amount of time yesterday and ran into a couple issues. First, it seems as if the car has been running tremendously hot since we got it running. Its probably only had 100 miles put on it, but the gauge appeared in the normal position. Well we put a different gauge on it and found out otherwise. We pulled the t-stat and found pieces of an old t-stat behind it. It seems a broken t-stat was never removed. So now that it seems to be running alot cooler (180), but when I really get on it for a few minutes, the temp is back up around 210. The other thing is that when im getting on it, smokes coming out of the exhaust. Usually once I hit about 4k rpm. I checked the oil, and it appears to be free of water. Do you guys think I blew a headgasket? Any ideas on what the problem may be? Thanks, -Ryan
