Hello, I have a .16 nitro engine and it has a side exhaust. The gasket connecting the exhaust manifold to the engine ripped when I took the manifold off. A small piece of gasket ripped off so I picked up the piece and stuck it back in the same spot it was before. It probably isn't 100% airtight anymore since the piece I put back in place doesn't exactly fit in the way it was before. This is now the 2nd exhaust gasket I've ripped. Is there any way to fix it without having to order a new one? I really don't want to have to order another one and wait forever to get it shipped here. Thanks
