Rough Running / Loss of Low-End Power

Diagnosis & fix steps

LOGIC: Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A). ACTION: Remove upper timing cover. Verify mechanical timing marks on the crankshaft dampener and camshaft sprockets; inspect hydraulic timing chain tensioner ratchet teeth for wear.

Red Seal field insights

Tensioner Collapse: Sludge or low oil pressure causes the hydraulic tensioner piston to collapse during startup, allowing the timing chain to jump one tooth on the intake gear.
