How to check for exhaust leak

I have a feeling there is an exhaust leak putting fumes inside the cabin of
my '94 Chevy S10. It does seem to have a noticeable smell, although not
like antifreeze.

Isn't there something I could pore into the engine while it is running which
would produce smoke at any leak location, like the exhaust manifold gaskets.

Many years ago I read about a ''trick''.I think it was in an old Popular
Science article which dated back to the 1950's,Auto Kinks,Hints,or
something like that.It pertained to drilling and threading a hole in the
exhaust pipe near the exhaust manifold and installing an Alemite grease
fitting.The gist of it was by using a grease gun and putting a dab of
grease in the exhaust pipe/tail pipe,that was suppose to make the pipe
and muffler last much longer.It probally made the tail pipe and muffler
kind of smokey for a while too.

Any oil. Dump in carb. Partially plug the tailpipe for best results.

Get some GM top cleaner and you can kill 2 birds with 1 stone.

Will GM top cleaner work ok for my 1978 Dodge van,318 cubic inch engine?
