Filter Fail

This bulletin applies to 2017-2019 Chevy Colorado and GMC Canyon trucks equipped with a 3.6L engine. Some customers may comment of engine noise or engine failure shortly after an engine oil change and a MIL on.

The condition may be caused by a missing oil filter adapter insert/bypass valve that was inadvertently removed during a previous oil change. Also, the retaining tabs on the insert may not be robust enough to retain the insert during an oil service if the filter is crushed.

If a vehicle comes into the shop with one of these conditions, inspect the oil filter adapter to see if the center insert/bypass valve is missing.

Upon inspection, the technician may find that the oil filter has been damaged or material from the oil filter may have been pushed into the oil galleries causing an upper engine noise.

If no mechanical damage is found, inspect the oil filter for damage. If there is paper debris, codes and/or cam actuator noises, that does not require engine replacement, repair and/or replace the affected components and clean the engine thoroughly.

If engine noise is present, it will be necessary to inspect the engine to see if any damage has occurred such as a damaged rod bearing.
