Running another problem.

[FastAndFurious]

Finally my car is fixed and runs.

I just did 60k upper and rod bearings.
Now, it's making a knocking or tapping noise(sounds like sewing).
Unpluged vacuum but the noise didn't go away. The noise gets faster as I rev the engine. It never goes away. It seems like a shim failure but I'm not sure. Car runs awesome btw. There's no power lose or anything. Just that noise is making me nervous. Give me any ideas.

Thanks

So how did you fix it?

some times the SHO can sound like a sewing machine.

If the tap is loud it can be the cam tension has failed. Where is the sound coming from?

I meant i fixed rod bearings and stuff.
The sound is coming from in the center of engine. Front valve cover, I think. I'm guessing I have to pull the intake out?

read this and follow the same procedure.

I figured it out. It was butterfly. I thought I tested vacuum but I didn't so I removed vacuum hose and it didn't make any noise anymore.

I wonder if you can actually remove that noise by replacing whatever is making that noise.
