Civic 1.8 Engine Noise ... why?

[aerobrain]

Hi ...

I bought a Civic 1.8 year 2006 about 4 months ago. Recently I notice there is a gurgling/rattling/knocking sound during start up and during 2000-3000rpm when free gear. I went to Honda Service today for regular service and at the same time asked them to check on this. However, they could found that the sound coming from the engine itself and they suggest overhaul .. I think 3-year-old is too young to be overhauled. Appreciate if anybody has any comments.

I posted some video here .. please hear carefully:

btw...honda put a lot of effort to make this engine perform like a 2.0 while consume fuel like 1.5..it has many high tech friction reducer in the engine..it has special coated piston skirt and also a oil jet to cool the piston which onli normally found in higher performance engine...so it really shouldn't sound like tat...tats like a dog meowing.....:hmmmm:

I think you should go and overhaul the motor. If its still under warranty, why wait?

Go go go go go! Open up the motor.

hope you catch my drift

Something is loose or knocking inside...?? For sure the engine sounds really rough.....should it be that rough?
could it be the timing chain?

just need to retorque the bearing cap.

Meaning need to change any parts or not? Because some people said that conrod bearing is very expensive.
