Exhaust Manifold

CLEANING
Clean the cylinder head and exhaust manifold sealing surfaces with a suitable scraper. Use a Scotch-Brite pad or equivalent.

INSPECTION
Inspect the exhaust manifold for cracks. Measure the exhaust manifold for flatness. Place a ruler over all of the exhaust ports and insert a feeler gauge between the port flange and the ruler. Replace any manifold that is cracked or warped.

EXHAUST MANIFOLD FLATNESS: 0.20 mm (0.008 in.) MAX.
