All: I have a 1998 Toyota Avalon XL with around 75000 miles on it; and, I have been noticing white smoke coming out of my tailpipe when I cold start it. The smoke goes away; and so far, there are no engine problems. Is this either a present sludge problem or a future sludge problem? This car recently went through a big Toyota inspection; and, they found nothing wrong with it. Just curious if this is a problem or not. Thanks!
