probably been posted before but i couldnt find it. i have a minor engine knock (nothing serious and the noise cant really be heard outside of the car.) when my car is cold and in idle and also at lower rpms.
ive had this for a while and im guessing its normal for our engines but if it isnt feel free to post some possible problems. |

QUOTE also, read this site: http://remanufactured.com/Engine_Noise_Diagnosis_101.htm When the engine is cold, the aluminum piston is small in comparison to it's iron cylinder. Therefore the rather hollow slapping noise will be loudest first thing in the morning. After the engine warms up, the aluminum piston heats up faster than it's iron cylinder, cutting down on the excessive clearance between the piston and cylinder wall. - this is a quote from that site. sounds about right. might be a possible diagnosis. |
