What are these?
The second thing fell out of the motor from somewhere during tear down. I think it was between the block and the oil pan where the 2 ports are for the oil filter but I am not sure. Is it something I really need? I already put the pan back on and forgot it fell out.
The second pic looks like it's part of an electrical connector.
The plastic piece looks like it came from the knock sensor connector. I am assuming your engine has the knock sensors in the valley cover?
