I need to replace the exhaust manifold gasket on my '86 FJ60, and I'm not sure if I want to tackle it myself, or have a shop do it (Cha-Ching!!). Anyone having experience with replacing this vintage exhaust manifold gasket replacement please post up with your advice: i.e. are the manifold bolts prone to breaking off in the head? Are there any tips or tricks to replacing this gasket, etc.? Thanks in advance for your response.
