TURBO Noise?? help

[Dudee]

I have an 03 Pajero FM, local... pag umabot ang rpm sa 2000,whether standby or running, there will be a loud sound coming from the intercooler, parang "wwwwiiiiinnnningggg...."...

I tried doing a some testing.. When I disconnected the suctioned (upper) hose of the intercooler, wala ang sound upon rev... Pag yun sa hose(lower) tinanggal then connected upper hose, may ingay pa rin.

Can anyone help? thanks

Turbos do have this sound, but not so loud. If it is unusually loud, the turbo may have to be checked. This is an 18 year old car.... normal wear and tear.

18 yr old car? medyo napaisip po ako dun sir. i thought it was a 2003 pajero.

btt, i agree with sir Dd, its a normal wear and tear. have your pajero thoroughly check at a specialized shop. dame naman replacements/surplus parts for that engine. and di naman din siguro ganun kamahal.

guess ko is a cracked tube/hose

2003 po ang pajero, it's a 7 year old pajero.

Pag may butas ang hose, bakit po may tunog?

its more of a whistling sound if hose ang butas

[Dudee]

its more of a whistling sound if hose ang butas

then it's not the hose, the sound is so loud and more like a "wing" sound...

I remember my pajero was ok 3 weeks ago , then I had the turbo cleaned kasi it was clogged na kaya may knocking upon acceleration. Could it be dun din naka problema?

How can I diagnose it?

[Dudee]

for now the only connection I get is that when I disconnect the hose of intercooler from the suction valve, nawawala ang problema (sound)... anybody encounter this prob?

Turbos really whine. It's normal. I'd advise getting a boost gauge (I have a Php500.00 unit on my Patrol).

Disconnecting that hose might not be allowing the turbo to work hence it won't whine.

A boost gauge will allow you to see if the turbo is making any pressure or not.

Sorry about the year Dudee.

You mentioned in your other post that this noise started right after you had your turbo cleaned. It is possible that the rotating components may be rubbing against the turbine and/or compressor housing/s. I suggest that you consult the workshop who cleaned your turbo.

Is power ok???

Power seem to be ok (i guess), but I'm not really that keen in assessing it (power).

"It is possible that the rotating components may be rubbing against the turbine and/or compressor housing/s" --- Will this worsen?
