Alyc Neutral Newbie June 1, 2005 Share June 1, 2005 Hi guys, recently when i'am driving, i hear a knocking sound from the engine. i can hear it thru the aircon duct from the driver's side. Seems a bit louder when i release my clutch, from neutral to half clutch position. It's a 1 month old optra sedan Anyone experience this before? ↡ Advertisement Link to post Share on other sites More sharing options...

Cbx750p 1st Gear June 1, 2005 Share June 1, 2005 That is kind of far stretch, don't you think ? How can a piece of magnet mounted out the rubber fuel line crack the fuel pump which is right behind the car under the rear passenger seat and interfer with the fuel line supply pressure ? Please !!!!!!!!!!! EDUCATE me Link to post Share on other sites More sharing options...

Seems a bit louder when i release my clutch, from neutral to half clutch position. It's a 1 month old optra sedan Anyone experience this before? Questions : a. How many time the sound appear ? Once or repeatedly ? b. What sound ? Tapping, Kocking, etc. Try to describe sound ! c. When do sound appear ? Driving, stationary, in carpark, during turn, driving over hump or anytime ? d. Does the sound coincide with any particular movement, like de-clutching, accelerating, etc ? CBX Link to post Share on other sites More sharing options...

My bro-in-law had a big arguement on 2 ocassions, wif the technical officer of the service ctr, even consider legal proceeding as they wanna void his warranty..

Sky8807 1st Gear June 1, 2005 Share June 1, 2005 Might be those items u installed to the engine. Not properly secured or fitted. Vacumn line is one main suspect. Why installed such items when u are not familiar with the engine in the first place? Link to post Share on other sites More sharing options...
Room430 Neutral Newbie June 2, 2005 Share June 2, 2005 Best is if you can PROPERLY uninstall all those gadgets and then see if the problems persist. If it still does, go back to SA to have them look at the problem...... without all those gadgets in of course. ↡ Advertisement Link to post Share on other sites More sharing options...
