The oil cooler design usually has an O ring seal at its base and leaks are common. That seal is likely as hardened as the valve cover gasket was. The oil pressure sensor (OPSU) leaking through the sensor is also common. This one can get quite large. The leak at the Knock Sensor is odd. Never seen that before. If you want to know for sure what is leaking ...

I actually had an oil pressure sender leak in a similar fashion. Not from a leak around the sensor thread, but actually through the sensor itself. Your question has a simple answer, replace the sensor. The internals of the sensor has degraded due to pressure/temperature/age or whatever enough so that the sensor is no longer sealing the inside of the engine ...

It sounds like you are starting the journey investigating how your car works and how to maintain it properly. Awesome. I recommend that you start the trip with the purchase of a service manual (either Haynes or Chiltons) They run about $30 USD. That book will help you understand how things work. They provide troubleshooting guides for repairing issues. ...

Number 1 looks like your intake manifold and number 2 is your intake hose leading to the throttle body. If 2-3 ounces of oil come out of #1 when #2 is removed, that's ok. It's most likely oil that's been pushed up by the PCV (Positive Crankcase Ventilation) hose. (Your motor doesn't have a PCV valve, just the hose with a filter on it. Ahhh, Chevy...). If ...

I agree with Paulster2. Leak down test is about compression rings, not oil control rings. You can have good compression/leak down and consume oil. I would look at the pcv system. If there is too much "blow by" the pcv cannot keep up. Make sure there is vacuum to the pcv, and enough vacuum. A stopped up pcv vacuum port/line will cause excessive oil ...

Not a desired answer, but with no leaks (to ground or into coolant) it's possible that your engine is just using/burning what some manufacturers would consider a normal amount of oil: How much is too much? Audi, BMW, and Subaru stick firmly to the statement that oil consumption is a normal part of a car’s operation. Subaru considers a quart burned ...

I'm wondering if you are having an issue with oil bypass, as in going through the breather/PCV and ending up getting burned through the intake. A simple catch can would prove this out for you. This happens quite a bit and is easily solved. Two things. The leakdown test will not tell you anything about your oil loss. Its not what a leakdown test if for ...

You can do a leak down test but look at your spark plugs first If your burning oil you will see it on your spark plugs. They will be black and have buildup on them. If you find one or two that look that way and all the others are very light in color to tan then you probably have oil getting into the combustion chamber. Here are some nice responses ...

If it is the oil pan bolt holes that are stripped out, using a Heli-Coil thread insert is the professional permanent solution. Heli-Coil is the inventor of this repair method, but there are other brands now available that do the same thing, they are sold in most Auto parts stores here in the US. Using Epoxy to do this type of repair is similar to using ...

I really think it depends on how they are using the glue. If they are using it to fill in a void, then it might work. You WOULD NOT however, want to use it to seal the leak directly. For instance, you don't want to glue or bond the two metal parts together in lieu of a gasket or gasket material. They (or you) need to figure out where the gasket is leaking ...
