my mechanic told me today that the cause of this strange noise is the OIL CATCH TANK! i still cant believe it, gonna replace it tomorrow and see if its truly this! we checked the timing chain area and everything seems pretty alright...

Glyn M Ruck

Well remove the catch tank & see if the noise goes. Easily checked.

LightDragon

i cant remove it , its necessary for the car to start up. Ill check it tomorrow and post comments/results but anyone had a similar issue ?

Glyn M Ruck

What oil catch tank are you talking about? Inlet system?

LightDragon

ok doesnt matter, i replaced the damn thing today and the ****IN NOISE IS STILL THERE! im DESPERATE!!!! it's a "rrrrrhhhh" noise !!!! i cant figure out what causes it nobody can!

Carsy

Can you post a sound clip?

Glyn M Ruck

+1^. Lets hear it & go from there.

LightDragon

thanks guyz. Ill try recording it today, hope it leads us somewhere!

When i had my noise, I recorded a short video with my iphone and uploaded to youtube. If your looking or an easy way to do it.

LightDragon

it doesnt sound clearly when i record it i can specify the area that the sound is comin from! its heard like something is loose and it trembles, rrrrrrrrr like a whistle. i can hear it from the right side of the engine and today i reconsider if its coming from the back area of the engine! the strange is that when i disconnect the s/c it isnt so loud!

LightDragon

visited another mechanic today. he insisted that the noise comes from the timing chain case! when the s/c's belt if off the noise goes out about 80% so what has the timing chain area to do with the s/c ?

LightDragon

FINALLY I MANAGED TO RECORD THE SOUND! HERE IT IS, UPLOADED ON FILESONIC HOPE IT HELPS TO GET TO THE POINT!

With the load of the auxilliarys on the engine it could be enough to take the slack out of the timing chain & make it run on the loaded surfaces on the chain & sprockets to make it sound quieter.In other words it could stop it flopping around & making a noise.

I would put a new aux belt on first before doing anything else.

I put a new belt on & it quietened my noise immediately.

You are always going to have some cam chain/sprocket noise.

I cannot download your sound clip.

on 2nd thought! HOW does a HEADERS leakage sound ??

Glyn M Ruck

That sounds typical timing chain or cam adjuster to me.

Header/exhaust manifold leaks have a loud pfft, pfft, noise of gas escaping when the exhaust valve opens for that cylinder.

My mechanic, when in trouble to find out the origin of mysterious noises, is using a doctor's stethoscope, with a plain steel stick at the end, instead of the usual little round diaphragm!!!

LightDragon

take a look at this video. i think its the exact noise!

Tappets ? .More than one .

Take your oil filler cap off to see whether the noise increases . Watch for oil splatter.

I would consider removing valve cover & checking wear & clearances.

Glyn M Ruck

You might have multiple damaged hydraulic lifters?

LightDragon

is timing chain tensioner and cam chain tensioner the same thing ?

Glyn M Ruck

Yes.

i thought that 26 was a 2nd tensioner

Glyn M Ruck

All 3 are timing chain tensioners by definition.
