Hey, any ideas what this noise is? I think it has been happening for a while, but has gotten louder in the past couple of days. I've heard that it could be the solid lifters tapping, but I just want to make sure it isn't something super serious. I am running 10W-40 conventional and I have 2000 miles until the next oil change. My engine has been rebuilt by Toyota and has just under 70,000 miles on it. I rebuilt the tranny and it has 9000 miles on it. Here is a link for a video.

Looks like it's in rhythm with the timing belt slapping, it shouldn't be slapping.

The tension could be wrong then? Or would the belt need to be replaced?

How much slack is there with the engine off? It should be pretty taught.

One side is pretty tight, as you move down the belt it gets sloppier; it's not that horrid though.
I'll have to go take another look. |

It is hard to judge 4 lb of pressure, but it seems like more than the 6 mm allowance.

You could get a cheap fish scale.

After further analysis, it looks like the tension is correct, the belt is also pretty much centered.
