Disadvantages of the GM L92 engine
Keep an eye on the radiator and pump’s condition; overheating causes many engine issues;
The primary cause of floating engine speed is contamination of the fuel pump and throttle;
An ignition coil crack is the most common cause of this unit’s tripling;
Reduced lubrication frequently causes the camshaft liners to wear down quickly;
The thermal casing and exhaust manifold bolts that are falling off are also criticized on specialized forums.
