If the seal is broken, the exhaust gases break out, accompanied by a characteristic sound (collector “cuts”)</span >
If retightening the exhaust manifold mounting fails, replace the gasket.
Disconnect from the exhaust manifold or remove the exhaust pipe from the engine, for this:
We unscrew the four nuts and locknuts securing the exhaust pipe of the muffler to the engine exhaust manifold
We 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 set aside the vacuum booster hose.
With a 14 head, we 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 for attaching the water intake pipe
remove the exhaust manifold.
Remove the exhaust manifold gaskets from the studs
We 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.
