I agree with Tony! In order to fix the leak you need to find the leak. If you have a cracked hose you replace it, if you need a new gasket you replace it. If you put in some sort of "stop leak" fluid you can actually destroy the gaskets, and seriously mess up the engine.

Using that stop leak is a cheap and nasty fix. If it works.

Reminds me of a old saying
The bitterness of poor quality is remembered long after the sweetness of a low price is forgotten.

RE: to use 'stop leak' or not to

I also have an 89 Porsche with a small leak in the rack.
I asked the indy mechanic to put stop leak in there; did not give me much of a fuss. Says that the stuff swells the gaskets, etc.

I am going to take the S600 into the dealer to tell me exactly what is leaking before I do anything on that one.

Ideally, everyone is right: fix it properly.

RE: to use 'stop leak' or not to

Bars All works well for small coolant leaks. If you do a little research you will find that the majority of auto manufacturers actually installed stop leak into the coolant system of new cars before leaving the factory. If the radiator is in good condition-not clogged by rust and other deposits-there are no side effects using this product as directed by the instructions. Oil leak products are another story. I've used them with very limited sucess. There's really no better solution for an oil leak than repairing it properly. As far as small head gasket leaks and minor cracked blocks-K&W Block seal works wonders. I've used it over the years in some of my personal vehicles with excellent long term results.
