used)
Inspect Exhaust Manifold
IMPORTANT: Some early production exhaust
manifold end sections (D) may have
three sealing ring grooves (B) and
may have been assembled with only
one sealing ring. ALWAYS use two
sealing rings during engine
reassembly and use outer grooves
on manifold sections with three
grooves.
1. Inspect machined mating surfaces (ID and OD) for
burrs, cracks or other imperfections which may
prevent sealing rings (A) from sealing properly.
2. Inspect area past sealing ring locations for evidence
of exhaust leakage. Inspect all sections for cracks.
3. Inspect and clean cylinder head and exhaust
manifold machined mounting surfaces.
