zameer Posted February 14, 2010 Share Posted February 14, 2010 I have a 2002 RX300, 100K MILES. I GET A RATTLE/METALLIC NOISE EVERY TIME I START THE CAR IN THE MORNING OR AFTER THE CAR HAS SAT FOR A LONG TIME. THE NOISE LASTS BARELY A FEW SECONDS AND GOES AWAY. MY GUESS IS IT IS EITHER THE STARTER PINION WHEN IT ENGAGES THE FLYWHEEL GEAR OR SOMETHING IN THE VALVE TRAIN? CAN SOMEBODY SHED SOME LIGHT ON THIS OR HAVE HAD A SIMILAR PROBLEM AND HOW BEST TO DIAGNOSE IT OR GET IT FIXED. THANKS Quote Link to comment Share on other sites More sharing options...

THANKS Wild guess - does the RX300 have hydraulic valve lifters? [Could be the lifters until they get 'filled' with oil?]. Quote Link to comment Share on other sites More sharing options...
