I'm getting ready to list one of my Mark VIII engines for sale, so I've started cranking it and running it regularly for the last few days (it's still in the car). I've noticed smoke coming from the very back of the engine, just to the passenger side of the throttle body (this is a 93, so the TB is at the very rear). I did a google search, and it brought me back here to an old post from 2006 that didn't really provide any clear answer. I'm starting to think it's an exhaust leak, but I'm wanting to get opinions on ideas on other things it may be so I can hopefully rule them out. This is a very smooth-running engine all through the powerband, from idle to redline. On the post from 2006, someone mentioned it might be the EGR tube, and since the smoke is coming from the passenger side rear of the engine, I'll be checking into that tomorrow or whenever I get the time. Any other ideas of things I should check out? If it's an exhaust leak, I'm not concerned because this is a parts car and I don't plan on selling the exhaust system, but I'm mainly concerned about any possible problems with the engine, since I don't want to sell someone a bad engine.
