Reddit mentions of ACDelco 25183348 GM Original Equipment Valve Cover Gasket

Most here think it could be your valve cover gasket. No way to know 100% unless you were to see the source. I am leaning towards the valve cover gasket because I can see the oil drip (especially around like where the dipstick is) and also because those are things that are known to break. Some people here say head gasket but i really think thats unlikely because usually that is accompanied by a loss of coolant. If you change your oil and you see coolant then that's it. That is an involved repair.

The good news is if it is your valve cover gasket this isn't super urgent so long as your oil levels dont fall too low. A lot of people are driving around with leaky valve cover gaskets as we speak! My gf drove around with a very slow VCG leak for years. If it's a head gasket or a

The other good news is on your engine it is very easy to access, and amazon has the replacement part for $5 USD https://www.amazon.com/ACDelco-25183348-Original-Equipment-Gasket/dp/B014MVJ87I (AC Delco is General Motors, so this is the actual original equipment manufacturer). Your local auto parts store would also have it in stock. To access you would just need to remove the ignition coil assembly (the black thing with two black "humps" bolted to the valve cover with 4 wires coming out labeled 1,2,3,4). And bolt off the valve cover. Probably good to disconnect the hoses. I would change the spark plugs while you're down there (the things at the end of those labeled 1,2,3,4 wires)

The medium news is that you will need to find someone with tools to do this. Tools can be expensive. You might be better off going to a mechanic unless one of your friends has tools. The mechanic will have all the tools and be sure to torque down the bolts in the right sequence and torque values. Some valve cover gaskets also require RTV silicone (less than $5, also available at auto parts store) but you have to know where to put it. My only concern is some of the bolts appear corroded and *may or may not* get stripped or break upon removal. Not saying that's a guaranteed or even a big deal but you have to have the tools and knowledge for how to deal with it. That's why im leaning towards a mechanic or a friend with a lot of tools.

The kind of concerning thing is The engine is actually built by Daewoo in south korea which is not known for reliability. Not saying there’s anything wrong with it but something to keep in mind
