Hello to all Sifus & Taiko's in the club , am rather new in this club and this is my first post . Anyway , have already done introduction in the newbie section about a month back and have been referring to your very informative forums which has helped me learn a lot about my new machine . As referred about the noise ... after driving on the highway yesterday nite from KL to Seremban .... averaging speed of about 120 - 140 KMH ( never exceeding 160 ) and a slow drive into our destination near Seremban town ... when I got down from the car after turning off the engine ... about 30 seconds later ... i could hear this noise ... " Puff...... Puff....... Puff " averaging about 1 seconds before the next "puff" from the bottom of the car ... like as if water was boiling and overflowing onto the floor under the car . It lasted for about 10 - 15 seconds max. I then proceeded to turn the ignition key to check temperature and all was normal ... I even reversed the car to see if there were any leakage on the floor but there was nothing . So ... obviosly left the car and continued to do what i was in Seremban for . I even openend the engine compartment to check for any leakeage or burst radiator but did not discover anything unusual . So .. to all sifu's and knowledgeable forumers out there , if ever any of you did encounter this situation before , I really would like to hear your story and hopefully solution if it is even a problem. I sure hope nothing serious is wrong with the car . P.S. : forgot to mention that the car was parked at a slight angle ... about 12 - 15 degrees slunted ( passenger side elevated ) when heard the sound .Thanks in advance guys . Xander
