92 SE - post-intake gasket replacement questions
Thanks in advance for any help. I have a 92 SE with 159,400 miles on it. A couple of weeks ago it started smoking real bad all of the sudden - thick white smoke. I parked the car immediately and checked the coolant. The overflow bottle was empty and I couldn't see any coolant in the radiator. There were no obvious signs of leaking coolant. I drained the oil right away, but other than being dirty it didn't really look milky. Since my car is EGRless, I assumed it was the lower intake manifold gaskets, so I replaced the gaskets and seals. I also replaced the throttle body gasket, vacuum hoses, coolant temperature sensor, and put in a new 180 degree thermostat. I got everything back together and filled the oil and coolant. Once everything was back together, it took only a minute to get the engine to turn over and it ran just fine. At first there was a little bit of steam out of the exhaust, but as the engine warmed up it started smoking more, although not as heavy as before I replaced the gaskets. I only ran it for about five minutes, but it kept smoking. The smoke was more grey than white or blue, and just smelled like exhaust. Even though the SES light did not come, I pulled the codes anyway and there were no hidden codes.
Any ideas? Based on what it looked like I'm pretty sure the lower gasket was at least part of the problem, but I can't figure out why it is still smoking. Is it just burning off moisture or coolant that was still in the system? If so, how long should that last? Thanks again for any help.

Okay, I need more help. I have let the car run several times for up to 1 1/2 hours. When first started, there is no smoke. After the car warms up for a few minutes, it starts smoking and does not stop. The "smoke" looks just like steam - kind of greyish/white and water drips from the tailpipe until I turn off the car. It just smells like normal exhaust - no oil or coolant smell. I am not losing any more coolant, nor am I getting any oil in the coolant. In addition to the work I initially did on the car, I replaced the O2 sensor and the PCV valve. The gas has been in the tank for over a month. I added a moisture remover to the fuel just in case. None of this made a difference. I have noticed a little noise coming from the area of the cat but it could just be my imagination. Someone please help before my wife makes me buy a new car!

Thing is that if it doesn't smell raunchy like oil, or sweet like coolant, and just mells like exhaust,, then it must be.....we've had 50'* here in MN and I've still had that? But if that'* not normal for your area, then could it possibly be a really rich condition?
It is normal for a little while, until the engine warms up, but this keeps smoking. It also increases when you rev it a little. I thought the mixture might be off, that'* why I put in a new 02 sensor. I've pretty much exhausted (pun intended) my ideas.

Mine will smoke like that until I start driving and then it will go away unless I'm stopped.....and even then it'* pretty faint then but if I stop and let it idle again....The combusiont chamber temp drops and that where it comes from.
