NOt to say that I hate the valve train noise, I have had a C5 so long that I almost consider it part of the charm.
But, I was wonder if a valve adjustment woudl cure the diesel sounding nature of the V6. Every other V6 I have owned has been quite and smooth, the 2.8 and 3.0 sounds extremely loud for a V6 and as the revs climb it is far from smooth.
I knwo that some here have had their cylinder heads replaced, did that cure the valve tapping sound?
I never drove a New 2.8 or 3.0 so I dont knwo how much worse my engine is when compared to a new one.
Any thoughts?

The fuel evap valve clicking bugs me more than anything.

DesmoTesta

is that the clicking sound seemingly coming from behind/under the instrument panel?

I've never experienced any valve noise on either my 2.8 or the 4.2. What oil are you using?

DesmoTesta

The castrol Syntec from the Approved list, did the same with my 99 2.8

I researched it and did some poking around under the hood when it was being particularly loud.

yeah, buy a 2.7t or a 4.2

The only time I had valve lifter noise was when I discovered I was low on oil. The 30v 2.8/3.0 should have a silent head. Try a thinner synth oil for the cold weather.

5W-40 gives my wagon a back lower end knock for some reason.

on my 3.0 sedan back in the day, my dealer was pushing 15W-50 Synthetic through it...bhwhahahaha
