Re: Knocking noise comes and goes
Fixed it!!!! It was a vacum hose under the car it runs to the back somewhere. It was unhooked. And sucking air in. Making a "puffing" "knocking" noise. I could put my finger over it. And it stopped. Hooked it back up. And no more noise! This was the simplest thing. And I was scared the motor was ...

Re: Knocking noise comes and goes
I have a friend who offered to look at it later this evening. He said he has ramps. I told him I would buy him and his family pizza. If he can just get under there and take a look. I will report back tonight. And if anybody else has any ideas. Please leave them here.

Re: Knocking noise comes and goes
Here it is. I think this video is going to give somebody an idea of what is happening. Notice. The noise just completely stops at the end of the video. Im starting to suspect an exhaust leak. And im not strong enough to free the bolts on the tire. To get it out of the way. But I put my hose onto ...

Re: Knocking noise comes and goes
Ok. I had pulled the top timing cover off to inspect that area more. And here comes the noise. Not very loud yet. And kind of coming and going. The next video im uploading is the one you will want to see.

Re: Knocking noise comes and goes
Ok. So here is a video of the car warming up. Absolutely no noise present. So you will believe I am not crazy. This just comes and goes. Took about 15 minutes before it presented it self. And I am posting that next.

Re: Knocking noise comes and goes
Ok. Here is an update. And I think the original location of the noise is not correct. I used the hose. And can not detect the noise any where near the timing belt. Or near it. On the back of the motor. This time it took about 15 minutes to present itself. And not very frequent. But I have discovered ...

Re: Knocking noise comes and goes
They claim it has a new timing belt. So I was thinking maybe they did not replace. Or properly adjust the tensioner. And when it is getting warm it is failing. And causing a slap in the belt? Maybe why the noise comes and goes. Because doesn't the tensioner open and close at different temperatures ...

Re: Knocking noise comes and goes
Hmmm tensioner? Or pulley bearing? I personally dont have the tools or any idea how to inspect further. I have found this issue all over you tube. And they all go cold. Nobody has said what is the cause. And this is a very nice car. I hope to save it. Or maybe I can just drive it like this?

Re: Knocking noise comes and goes
It honestly sounds different in person. On the camera it is drown out. I compare it to holding a playing card in a fan. And is very close to the pulleys and timing belt. On the back side of the motor. I will try to get a better video. Tomorrow. And move around the back side. It is just confusing. Im ...

Re: Knocking noise comes and goes
Here is a video. It is hard to hear over the valve noise. But when I put the camera down behind the timimg chains you can really hear it. And when I take the camera inside the car. You can hear it. It was hard to get capture it. I had to start the car. And just wait for the noise. It took about ...
