Thread: Chirping noise in D2 TD5

Hi Discomania
Firstly there is no timing belt on the TD5,if somebody charged you to change it I would be paying them a visit with a cricket bat,the TD5 has a timing chain that self tensions and doesnt need replacing.
I wonder if what you are hearing is the wastgate opening when full boost is reached??? I heard a similar noise on mine whilst driving up some steep hills around Esperance,never heard it before or since,at the time I did the run several times to try and find the noise.At the time I put it down to the wastgate opening.

Thanks Landy,

I'll chase it up. I've done a fair bit of towing with my TD5 and plenty of hills but the chirp is a recent addition to the repertoire.

There's no interruption to power or revs, it sounds like something briefly rubbing/slipping.

Check the exhaust manifold nuts & studs.
A slight exhaust leak will chirp initially & the Td5 is renown for breaking exhaust manifold studs.

From what you describe,its the same noise I had,only happened whilst ringing its neck in 1st and 2nd on steep hills.
Andrew

check number 1 and 5 cylinders on the exhaust manifold prone to breaking these studs or the nuts come loose do a search on this subject there are a few mods to do to the manifold plus get it planed as they do warp

My vote is with Stevo,, The chirping will most likely be the manifold
The symptoms are exactly what my bus first starting doing before it developed a noise under hard acceleration somewhere between a jet and a fart
While it was just a chirp I could not see anything obvious, but get a torch and mirror and have a good look around number 1 and 5 you will probably find a blow down there somewhere.

is the main problem just a case of mismatched metals not expanding at the same rate?

Never knew the chirp. So now I know my exhaust gasket was probably blown before I got it.
Discomania you are certain its not your aircon? Mine has taken up that habit every now and then.
