If the seal of the gasket is broken, exhaust gases break out, accompanied by a characteristic sound (the collector “slashes”)
If the problem cannot be resolved by tightening the exhaust manifold, replace the gasket.
We disconnect the exhaust pipe from the exhaust manifold or remove the exhaust pipe from the engine, to do this:
Unscrew the four nuts and locknuts securing the muffler exhaust pipe to the engine exhaust manifold
Unscrew the bolt securing the exhaust pipe of the muffler to the bracket on the gearbox
Having loosened the clamp with a screwdriver, remove it from the fitting and move the vacuum booster hose to the side.
Using a 14mm socket, unscrew the eight nuts securing the exhaust manifold to the block head.
Remove the washers and screen from the studs
Remove the engine lift bracket
Remove the bracket securing the water intake tube
Remove the exhaust manifold.
Remove the exhaust manifold gaskets from the studs
Carefully clean the mating surfaces of the cylinder head and exhaust manifold
We mount the exhaust manifold in the reverse order, having previously installed four gaskets on the studs.
