Guys, have a listen to my poor old 4 banger. It started making this hellacious squeal Monday. At first it was intermittent, but now it's there all the time & getting louder. I don't think she has many miles left in her.
At first, I thought it was a bad idler pulley or water pump bearing or maybe my new HO alternator. So I took the belt off to rule out something internal, but no dice. Even with the belt off it's still there. It's loudest right in the middle of the head around the intake/exhaust manifolds.
Any ideas? I figure it's a bearing fixing to seize, maybe a cam bearing?
