Amplification
High Manifold Pressure may be a result of cold oil and the affect of
high associated oil pressure on the wastegate controller. Maintain
power at or below 36.5 in.Hg by power lever management. If High
Manifold Pressure persists when oil temperatures are greater than
150°F, MAP controller requires a maintenance adjustment. If engine
surges are associated, MAP may be exceeding pressure relief valve
(pop-off valve) threshold. Relief valve will protect induction manifolds
from excessive pressure, but it may be a sign of a failed closed
wastegate; if this is observed or suspected, complete the Overboost /
Pressure Relief Valve Checklist.
