An exhaust-manifold gasket is more likely to need renewing than the gasket on the intake manifold, because of the greater damage caused to the exhaust system by heat; but the procedure is much the same for both.cfw oil seals skillful manufacture.
A ‘blown’ exhaust gasket can be detected by excessive noise from the exhaust, and by white burn marks around the manifold flange.
The intake and exhaust manifolds may be on opposite sides of the cylinder head, or they may be combined or bolted close together.dust seal.
If the engine has a V-configuration, there will be exhaust manifolds on the outer side of each cylinder bank, but probably just one intake manifold located in the centre of the V.
Apply penetrating oil to all nuts or bolts which have to be undone, including the exhaust-pipe clamp fixing.cfw oil seals skillful manufacture.
When the nuts or bolts are removed, the remains of the old gasket may cause the manifold to stick: tap the manifold with a rawhide hammer to loosen it. If any manifold studs are broken or damaged, remove them using self-locking grips, two nuts and a spanner, or stud remover .
Lift off the manifold complete with its carburettor – if the carburettor has not been already removed. Peel off the old gasket and clean the face of the manifold. If the manifold is water-heated, drain the water and remove the hoses. Use a socket spanner to remove manifold nuts or bolts.

With the manifold off, carefully scrape all gasket-mounting surfaces clean of dirt and bits of the old gasket. Do not allow particles to fall into the manifold or the cylinder head.
Check the manifold to see that it is not cracked or damaged; check its face with a straight edge — such as a steel ruler — to see that it is not warped. If it is, replace it.
Fit a new gasket, making sure that it is the right way round, with all holes lined up. On some engines a gasket may be in two or three pieces, or inserts may be fitted; be sure all parts are properly aligned.
Some water-heated intake manifolds, particularly on V-engines, require gasket sealant on each side of the gasket, because the larger water passages are more prone to leakage.
Reassembly is in the reverse order of removal. Tighten the nuts on the manifold, using a torque wrench adjusted to the setting recommended in the car service manual. The tightening sequence is usually from the centre of the manifold outwards to the ends.
After reassembly, run the engine to working temperature, switch it off and check the torque settings.cfw oil seals skillful manufacture.
