1994 intake manifold - replace?
I just purchased a 1994 SE with 97,000 miles. Everything ran fine when I purchased it, but it just smoked for about 1 minute after starting. It had sat for a few days and I figure it is oil leaking past a valve seal. After doing some reading it seems the 3.8l engines have intake manifold problems, but it is not clear to me if it happens to the L27 engines in a 1994. I was going to have it replaced to be safe, but now I am not sure. Should I have it replaced? Anything else I should have replaced? I want to avoid the engine failures I have read about.
