mga gurus...need your help again...paevaluate naman series of noise problem
ride is, MITS 7G '96, MT
1. once you turn the ignition on (on only not start) there is a momentary unusual sound that can be heard in the engine.
say, turn engine on > simultaneous, engine light on and sound in the engine (tsuk-tsuk), yes twice lang, then wala na > engine light off
the car will start without a problem.
2. when the car is running, say @ 60kph up, there is a audible (though not loud) whistling sound from the engine. this sound is intermitent.
3. when decelerating, a metal-sound like noise can be heard from the rear. particularly at the left back side. the sound is similar to a tin lid thrown on the floor, e.g tin cap of an half-gallon ice cream.
Have check the brake pads and rotors at the rear, okey naman.
IMO, items 1 and 2 are possibly related. Item 3 may be a suspension case.
Help please! :) Thanks!

1. Fuel pump priming yun, don't worry about it.
2. Could be air leak sa mga weatherstrips... Not engine related... Other than that, I can only think of expansion valve (A/C) noise.
3. Baka sira na stab link or bushing. Check brake caliper as well.

1. Could be your servo doing its self-test. Normal.
2. Check hoses. It could be coming from other sources aside from your engine though.
3. Clang!!?? Have it checked ASAP :D
