You may be surprÂ­ised to discover that a carbon monoxide (CO) detector really isn't a complicated piece of equipment. Housed inside a plastic chamber approximately 3 inches (7.6 centimeters) in diameter are parts that work in unison to alert a househoÂ­ld when lethal gas is detected.
This type of noise is usually caused by malfunctioning valve lifters or an exhaust manifold leak. If the noise lasts for more than a minute and completely disappears or dimishes after the engine is warm, the most likely cause is an exhaust manifold leak.
The turbo flutter noise is caused by having no blow off valve (or having the spring pressure set so high on the BOV it doesn't open except under high boost pressure). So to the OP, what you want is to either block off the standard BOV or buy one that's adjustable and wind the spring pressure up.he flutter or compressor surge is the sound a turbocharger makes when the throttle body snaps shut, the charged air has nowhere to go, so it goes out back where it came from, violently spinning the turbocharger from around its maximum of around 100,000 RPM to NEGATIVE revolutions, it is spinning backwards.
