It's a 1991 corvette. Nothing special like a zr1 or z06, just the standard one. I can't think of it off the top of my head. But I'll post it up later today. And that's the problem, we don't know where it is leaking from. We thought it was valve covers first then the LIM gasket so we changed them. But it is still leaking somewhere. We can't even pinpoint where it's coming from exactly but it keeps dripping on to the catlytic converter which is on the drivers side if that helps to diagnos it. And I think we used both the rubber piece it came with and RTV on the top and bottom of that.
