You can hear lifter click best around the top of the engine, and isolate the noise with a stethoscope against the valve cover. It will occur at idle and increases as you rev the engine, continuing even when the engine is warm. Valve lifter noise is detrimental and should be addressed quickly.
What kind of noise does a car make when it starts up?
It’s like an extremely loud rattling/clanking noise. It doesn’t do it when cranking, it’s only when the car first starts up (more noticeable on cold start-up). It’s also not every time you start it, only when it’s been sitting awhile (such as over night). I’m not exactly sure what it is but it’s pretty loud.
Are there any recalls on the Chevy Colorado?
From what I’ve heard the Colorado and Canyon tend to be fairly unreliable and have poor build quality. Malfunctioning lights are just part of the overall poor design of the vehicle. I’ve seen several, they always seem tough in the showroom but then in real life just don’t measure up. Too bad.
Is it normal for a car exhaust to make a noise?
Any time your car or truck starts to make a sound you aren’t used to, you’re going to notice.

A new sound coming from your exhaust system should never be ignored.
Why does a V10 sound so loud in a cold start?
V10s sound especially violent during a cold start. To start with, a car’s ECU decides that the engine has to idle higher when the engine is cold to stop it from stalling. This is programmed into the ECU via a start-up map, which allows a richer air/fuel mixture to enter the cylinders.

What causes an engine to clatter when accelerating?
There are guides for engines with a timing chain. Both vehicles with a timing belt or a chain have a tensioning system to keep it snug and centered. If the timing belt or chain tensioner loses its strength, the belt/chain has more movement than it should have. This causes engine clatter when accelerating and the engine clicks as it hits the guides.
What was the loud cold start knock that went away?
A few months ago my nephew went to a quick oil change place and they talked him into a “engine cleaning”. They added it to his oil, ran it for 15 minutes, drained the oil, changed the filter and refilled with oil. On his way home, the truck with 101,000 miles on it threw a rod, popped it right out of the side of the block.
