I have a 1999 chevy venture van. In 2004, the intake manifold gasket
leaked and I had it replaced. The mechanic changed the coolant to
dex-kool, a brownish coolant that was supposed to be safe for the gasket.

A few weeks ago, he informed me that the gasket is leaking again.

The van has been well-maintained and has about 85000 miles on it, so I
feel it has some life left in it. On the other hand, I thought I might save
some money and put in a sealant. One that was recommended to me is
alum-save, and one I found locally is Prestone Stop Leak.

I did an ask.com search and it seems that some people have had big
problems after using these sealants, so I am a little leery of using them.

Can anyone give me some advice about this?

Thanks

Stop leak products are stop gap products. They're Ok in a pinch when
your stuck somewhere, but are not a long term solution. They tend to
settle out the particulates into places like the heater core or settle
to the bottom of the engine water jackets. Those that jel are
equally evil. Fix the leak with a new gasket (sealed) and start
fresh for long term use.

I use alumaseal, the kind that Cadillac recommends.
Obviously, I wouldnt trust the car after using such a temporary
repair, but it works well for the short term.
