The Duramax LB7 engine may smoke at idle due to several factors, including injector issues, such as leaking or failing injectors that can introduce excess fuel into the combustion chamber. A clogged air filter or malfunctioning turbocharger can restrict airflow, leading to incomplete combustion and smoke. Additionally, low fuel quality or improper timing can also contribute to smoking at idle. Regular maintenance and diagnostics are essential to identify and resolve the underlying issues.

Some motors at idle are unable to burn the entire fuel charge because the combustion temperature is insufficient at that regime, what you see as white smoke is indeed raw fuel, it is detrimental for any engine to idle too much for the same reason I mentioned, because part of the unburnt fuel dilutes the oil and can cause lubrication problems in the cylinder liners and damage them as well as other parts that rely on lubrication.

The oil pressure in a Duramax diesel engine typically ranges from 10 to 40 PSI at idle and can go up to 60 PSI or more at higher RPMs under normal operating conditions. It's important to refer to the specific service manual for your Duramax model, as specifications can vary slightly. Consistent readings outside this range may indicate potential issues with the oil pump or engine health.
