2001 Chevrolet Silverado 1500 Z71 LS - I added oil and it is about 1/2 inch above the fill mark on the dipstick. Afterwards, I noticed that a small amount of clean oil is leaking on a newspaper underneath. The truck has 98,000 miles and is in very good condition and has been well maintained and has not leaked before I added too much oil. The engine is a 5300 Vortex. I have driven it about 100 miles and wondered if I have done any damage to the gaskets. I know nothing about vehicles but I have read a little and there is no "froth" on the dipstick. Could this leak come from a PCV valve? Do I need to have the excess oil drained? If so, will leak probably go away? Also does this engine hold 6 quarts of oil?
Thanks very much for your insight. Ben 🙂 /p>
It's not 100% clear from my 2 seconds of googling try checking the owner's manual and seeing how many liters it holds
It seems to be somewhere between 5 and 6
Could this leak come from a PCV valve?
there shouldn't be a great deal of oil in there, but why don't you look and see? How can I possibly know if your PCV valve is leaking?
Search for the leak. You need to look and see what's above the drip area. Follow the slime trail. Or use leak detection dye if you have to.
The most common culprits on GM's are the oil cooler lines.
