anyone experiencing or experienced a ticking noise from the engine? My 2001 LS430 has 69k on it and the engine is ticking. When I opened the hood this afternoon, i can also hear what sounds like... when you suck on a straw and tap on the end... covering air flow... it follows the rhythm of the ticking. dont know if there is any hydraulic hoses that were loose... at first i thought that it was probably the engine slightly misfiring... i will not rule that out though.. cuz i haven't changed the plugs yet. any insights?

Can you isolate where it's coming from? A stethoscope with an open-ended hose is often a great tool for tracking down the source of noises like that. Just move the open hose around very close to the engine (or other components) and listen. It's like a homing device.

its coming from the right side somewhere near the oil cap area.. i thought that the oil cap was loose .. but it isnt.

Have you been using cheap gas to save a few bucks? If so, try a tank of high test (93) and see if that helps.

no.. using premium .. highest available on guam is 91. mebe the gas here has gone down in quality... so it's a knock i'm experiencing?

The Check Engine light just came on! probably swing by the dealer to have it checked.

Sounds like an expensive fix. Make sure to keep us posted on how it turns out.
