Scotty, I have a 96 Buick century and it's leaking antifreeze to make a long story short, I had it pressure tested they told me it's leaking from the timing belt cover casket, but I read somewhere that if that was leaking it would be oil not antifreeze, is that true, and if it is are there casket sealant I can use to see if it works?

heck, try bars metallic seal up, auto zone sells it and it often works

Great, that goes in the engine correct?

There's a couple of them is there a specific one I should use?

yes, bars metallic seal up, that's the name, it's in a clear bottle with shiny silver liquid inside
