I Just changed the cams and started a engine noise

[walmore]

I was running my car with a compcams 127500, and I decided to change the cams for compcams 127300.... the problem is that started a engine noise like a lifter... but the lifters was fine with the other cams...

I have noise in my heads at very low rpm. I am running 127550 with limiters.

Curious as to why you stepped down from 500s to 300s?

My car makes a big noise

Can you describe the noise and what side it is from? Any CEL's?

The noise come from the left head, and the noise is like 2 or 3 lifter are bad

Ok; I ask because after I installed my HR cams I had one of the cam caps come loose and it made a racket...my loose one was drivers side and the one closest to the front of the car.

Then shouldn't you have went with the 127550 or 127350? The 127300, like the 127500, is for N/A.

a lot of persons have used 127300 in FI applications with good results.

Very true. I went from thumpr 3s to 600s and back down to 300s. Overall I think there the best cam for this car. All applications! Good power and they drive just like the stockers.

Both of my heads are making the same sound at the same rpm and goes away when below or above a certain rpm. Only does it when motor is warm I noticed.

 

[kahmann]

^What's the RPM it starts and stops?

 

[redstangs9308gt]

900-1100 rpm I am thinking it might be my limiters I hope so anyways.

 

[Noclutch]

Does it sound like this?

Left side, everything seems to be ok but that tick is not normal. I checked everything accept the towers, just saw this thread.

 

[redstangs9308gt]

Nope. All of my sound is coming right from the valve covers. You can't help but hear it. VERY loud chatter. But whatever it is, the sound is the exact same from left to right heads, at the same exact rpm.

 

[redstangs9308gt]

Sounds like this but at certain rpms but louder (I have no hood on my car right now soo) http://www.youtube.com/watch?v=pdbz9_CIaOU
Like this and same loudness only at certain rpms tho... http://www.youtube.com/watch?v=liqWdZ9qgOQ
Keep in mind this is a ALL NEW engine. Don't have 2 hours on it.
Really sucks
