Tick/knock? NOT LIFTERS.

[JonJames_dsm]

So, I had this noise coming from the head of my engine and I was pretty sure that it was lifter tick. I replaced the lifters with the revised version and the noise is still there. Any ideas? This is a post '97 GST with a 7bolt. It's not a swap, I just have a 1G BOV and a 6 bolt valve cover.Eclipse GST ticking - YouTube20121208 162435 - YouTube

Possibly rod bearing(s). The videos no good. Cant hear anthing over the exhaust

BTW you can rev it using your hand at the throttle body and have the phone record in different places.

But it didn't sound like rod knock. more like lifters.

have you checked for exhaust leaks? a small one can sound like a lifter tick

Although I cannot hear the sound of the tick over the exhaust I found out what the issue was on my car last night. I thought it was lifter tick but the noise sounded too odd so i looked down in the gap between the fender and the engine on the drivers side (where all the pulleys are) and my timing belt cover seemed to be loose on one side, it was vibrating then slapping against the motor (just plastic). So I used a screw to bold it down and no more noise. You would think this noise wouldn't have been that loud, trust me, it was loud enough for me to be concerned.

Good job figuring it out, could have been a lot worse!

Wow really? I really thought that was rod knock because it sounded just like that because for the most of the time when rod knock happens, it's when you it's a higher RPM but, rod knock also happens at idle too.

But anyways, good thing it wasn't that,. That would suck big time.

If you listen to the video that's titled GST ticking, you can hear the noise at 20 seconds and I'll start to play with the throttle to make the noise. It occurs around 2000 rpm and will go away around 4500rpm. And, the second video is much easier to hear the noise. It first occurs at 25 seconds and then it's really noticeable again at 35 seconds. It is for sure not the lifters, I just replaced them with brand new ones and it's not the timing belt cover either because, I just did the timing belt and this was here before and after and the covers are bolted down and secure, no movement.

It sounds like rod knock to me.

Why are you making two threads about the same thing. Just post results/info/updates in the firts thread.

GL with your car.

I hear a whining sound when you are revving it. Was that the timing belt cover rubbing ?
