Dirty hole; Spark plugs
CAR: 1997 camry le v6 XV20, 1MZ-FE 130,000 miles
The three front spark plugs are dirty as you can see in the video, the first is very dirty with what appears too be burnt oil sludge. 3rd hole was a little bit dirtier than the 2nd .
I was planning on replacing all 6 spark plugs but then i saw this. I had a mechanic replace the left and right valve cover gaskets a couple months ago, im unsure if the dirtiness happened before or after the valve cover gasket replacement.
Car doesn't have any stored or pending trouble codes, unsure of the maintenance history of the car but i wanted too replace all six plugs and wires because the car was getting bad gas mileage.
What should i do? Clean it? If so whats the proper way too clean inside?
One of the back spark plugs wires wasn’t fully pushed down because i heard a click when i pushed it down
