[Fwd: Re: [Chrysler300] Advice needed: 413 and 727 leaks]

[johnal <holst@xxxx>]

A trick i learned from a old mechanic on stopping oil leaks ( this works
on rocker covers, oil pans and transmission pans) is to take an
oversized punch and tap the back side of each of the bolt holes in the
pan or cover. this makes them slightly convex on the top side. thus
when the nuts are tightened additional pressure is applied out past the
area of the hole and transferred to more gasket area. over tightening
creates a concave area at the bolt and you get the leak back. so the
proper amount of torque is critical.
good luck
