So let me fill everyone in. I recently blew a spark plug and did some work on my car. I did the following to it during the build.

Ported head by LSJION
Smaller Pulley(3.0)
Bigger injectors
Complete timing chain

And after we had it all back together it is making a whining noise that goes with the rpms. I thought it was the water pump so i replaced that. Still makes the noise. Brought it to a shop and thay said it was the water pump too.

I told them i replaced it and they said it could be one of the other gears on the balance shafts but he said that it sounds like a bearing noise but doesnt know if the balance shafts have bushing or bearings.

He also thought it could be that my timing chain is too tight. Any ideas? Im stuck. here is the video:

Bump, anyone have an idea?

Get a stethoscope or a long screwdriver and find out where it's coming from. Don't just guess.

Re time it

MonsterDude72

I did, it sounds like its coming from the water pump which we replaced. Even after the new one the sounds still comes from there.

And the timing is correct. If anything im leaning towards the timing chain being too tight.

I appreciate both of your inputs though.

So after some more digging i found a Solstice thread where the person had the same problem and someone posted this...

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
A whine noise from the front of the engine may be experienced if the balance shaft tensioner has ratcheted out, causing the balance shaft chain to be too tight. In rare instances the balance shaft tensioner will ratchet out during service of the cylinder head, timing chain or if the water pump is replaced without using the water pump sprocket holding tool (J43651). This will cause the balance shaft chain to be too tight, which can cause a whine noise from the front of the engine.

Recommendation/Instructions:
Before attempting repairs, ensure that the noise is definitely abnormal by comparing the noise to other known good vehicles. If the noise is abnormal and the noise was not present previously, the balance shaft chain tensioner may need to be reset or replaced. Follow eSI repair procedures and reset/replace the balance shaft chain tensioner as needed. "

So my question about this is. Can the balance shaft tensioner be removed with out removing all of the timing chain?
