Clean the exhaust manifold using a suitable solvent. Use
a plastic scraping tool to clean the gasket sealing surfaces.
Inspection
-
NOTE:
New exhaust manifold gaskets, studs, nuts and/or
bolts must be installed when an exhaust manifold is serviced.
NOTE:
Use a Straightedge that is calibrated by the
manufacturer to be flat within 0.005 mm (0.0002 in) per running foot of
length, such as Snap-On® GA438A or equivalent. For example, if the
Straightedge is 61 cm (24 in) long, the machined edge must be flat
within 0.010 mm (0.0004 in) from end to end.
Using the Straightedge and a Feeler Gauge Set, check the
exhaust manifold sealing surface for warpage. If the warpage is greater
than 0.76 mm (0.0299 in), install a new exhaust manifold.
Use the General Equipment: Feeler Gauge
NOTE:
This procedure uses multiple tools/methods to help locate the
source of engine noise. It may be necessary to repeatedly compare the
sound between the tools/methods to help locate the source of the noise...
Bring the engine to normal operating temperature. Connect
the Vacuum/Pressure Tester to the intake manifold. Run the engine at the
specified idle speed...
