Rattle noise on start up...?


Recommended Posts

Nothing wrong with your car, them are normal sounds. All though oil filter brand and oil weight does have a effect on the noise. Cheap oil filters with inferior anti drain back valves allow oil to drain back out system, and upon start you hear the clatter from cam phasers and high pressure fuel pump. Until oil pressure and fuel pressure are up, so a 1-2 sec clatter totally normal. Longer may indicate time for a oil change or a poor quality oil filter.

I agree with crash712us.....

 

These Eco motors are fairly noisy overall, including at start up.

 

Most have heard the clickety clack of the HP fuel pump. Others have found out exactly what Chris is describing about the cheaper grade of oil filters.

 

Don't fret, as explained, it's normal.
