Name that engine sound
Can anybody tell me what this clacking sound is? My 3VZ-E has made it for quite some time, but only on the driver's side of the engine. Is it valve adjustment time?

Hey Yotaman. I have the same sound, mechanic says one or more ofthe bucket lifters on my drivers side may have cracked or collapsed. Im pulling the valve covers this weakend to fix a leak so I am going to have a look. Is yours louder when it is cold? It makes sense that it would be if your sound is lifters, because the oil has not worked its way into the valve train yet. Mine got worse when switching to synthetic as well. To thin an oil.

I'm sure that it's not the bottom end. In the video you can hear the sound coming from the valve cover area, so I figure it's the valves. Also, I know that the valves on my engine have never been adjusted so....... One more thing; if there is a noise coming from the top end of an engine, the noise would occur once for every two rotations of the crankshaft correct?
