2006 Chevy Cobalt Engine Locked Up after Oil Change
2006 Chevy Cobalt. Is there any service bulletins on The 2.2 ECOTECH oil filter gasket being cut, if installed Improperly? The O ring gasket severed during install 2 weeks later ran out of oil causing a rod to throw, but the canister did not leak after the oil change?
Answer: If the large O ring were to be cut or roll during installation, you would have an external oil leak right away. The small O ring on the tip of the filter being damaged would cause an oil pressure problem.
Answer: The only bulletin stated that if there is low oil pressure after an oil change, inspect that O' ring for damage caused by improper installation or being the incorrect filter. Have had a few do this after people changed there own oil or an oil change shop using a non factory filter. Some of the cheap filters had problems with this. Either because using the wrong filter, or it rips during installation.
The Service bulletin states...
"Oil filter misapplication may cause abnormal engine noise or internal damage. Always utilize the most recent parts number information to ensure the correct part number filter is installed when replacing the oil filter. Do not rely on the physical dimensions alone. Counterfeit copies of name brand parts have been discovered in some of the aftermarket parts systems. Always ensure the parts you install are from a trusted source. Improper oil filter installation can result in catastrophic engine damage and failure. "
