Engine System - General Information - Exhaust Manifold Cleaning and
Inspection
General Procedures

1. Inspect the cylinder head joining flanges of the exhaust manifold for
evidence of exhaust gas leaks.

2. Inspect the exhaust manifold for cracks, damaged gasket surfaces, or
other damage that would make it unfit for further use.

General Procedures

1. Using a suitable metallic straight edge and feeler gauge, measure the
cylinder head face in the areas illustrated. Note the maximum value.





2. CAUTION: Machine the minimum thickness of material from the cylinder
head to meet specification. If a selection of cylinder head gaskets are
available, increase the thickness of the cylinder head gasket by one
size.
NOTES: www.JagDocs.com

Prior to having the cylinder head machined, prior approval is
required by Jaguar or Land Rover engineering.


If the cylinder head requires machining, this must be carried out by
a local engineering company.

If the cylinder head exceeds the maximum value (0.2mm), the cylinder
head must be machined.

CYLINDER BLOCK Component Description



The cylinder block is a 90 degree configuration with cast-in iron cylinder liners and an open deck die-cast coolant jacket. The
low volume coolant jacket gives good warm-up times and low piston noise levels. The longitudinal flow design of the coolant
jacket, with a single cylinder head coolant transfer port in each bank, provides good rigidity and head gasket sealing.

NOTE: RH (right-hand) (A bank) cylinder head shown, LH (left-hand) (B bank) cylinder head similar.
