195K on the car, and as far as I know the engine is original.RickHaleParker wrote: ↑Thu Mar 01, 2018 12:21 pmHere is the link to 12 second video I took of the engine noise.
How many miles does the engine have on it?
Does the noise clam down when the engine warms up?
It sounds like Piston Slap to me, which is more of an annoyance then a concern. Anybody second?
The valve noise persists regardless of engine temperature. I wanted to test cooling system for leaks, so I let the engine warm up the other day. Every time I revved the engine up that same knocking sound only increased in frequency.
Before I warmed up the engine I was only getting P0302 (Cylinder 2 misfire). Once it warmed up I got two additional codes, one for
VVT solenoid, and one for O2 sensor. To me the combination indicates there may be an issue with proper lubrication to the head, and that some of the valves are not performing correctly. Sounds like I'm picking up some Seafoam on the way home today.
