Red exhaust valve on 1 cyl. only Renix
When changing my exhaust manifold I noticed my #4 exhaust valve looking rusty.
The others look white as do my spark plugs which seems normal.
Is water getting in there and rusting it out?
She runs good and doesnt burn oil and has been passing smog with 474,000 miles.
No water in the oil or loss of water so I dont know if its a big deal.
