Re: How do you block the oil filter bypass?
ACDelco of today is not the AC-Delco of yesteryear (note the missing hyphen). It was pretty much sold off after the bankruptcy and many parts are low bid Asian imports, like oil filters.
This doesn't mean all ACDelco parts are bad. ACDelco "professional" is assembly line OEM grade. If you need an AC condenser, ACDelco units will have the correct number of tubes, the aftermarket is usually less tubes which means less cooling efficiency.
Pass on their oil filters. Reach for a known good brand name. Hastings, Wix, Mobil1, K&N... If you have piston rings from ANYBODY, chances are good Hastings made them.
How may I help you?
