[net.auto] Exhaust Manifold - help needed

nka@houxz.UUCP (N.AILAWADI) (04/27/84)

I have a '79 Chevy Malibu wagon with a "hairline crack" in the
exhaust manifold.  My mechanic says I'll burn a valve if I don't get
it fixed soon.  Is this true?  Are there any ways of fixing it cheaply?
Perhaps with high-temp RTV?
                                     Thanks in advance,
                                     Narinder
