Q: Oil is leaking onto the spark plugs

asked by on

Hi, I have a 2009 chevrolet traverse leaking oil from spark plug tubs. I thought that was the upper seals and I replaced them. When I removed valve cover I noticed that the oil leak was coming from where the tub connect with cylinder head in the lower part. I'm wondering if those tubs can be removed and resealable. please let me know. Any advice will be appreciated.
