Oil/coolant/fuel? In cylinder head
I bought a endoscope to check out the inside of the cylinder and see the condition of the head and I found these than and cylinder 3,5,6 I had some pooling of maybe oil? I’d like to get some opinions on it, specially 5 and 6 are pretty bad,
Additionally, it rained a few days ago and I Havnt driven the car, so I assume 5, and 6 spark plug holes ended up getting water in them, which is why I think cyl 5 has that brownish sludge, I believe that dropped down when I took the spark plug out, What do you guys think it is? I’ve replaced vc/vcg and fuel injectors, |
