Funny Ticking Noise. Can Only Be Heard Under The Car

[Beer Baron]

and well no ticking when cold, only when hot.

this is the final proof you need it's the manifold or dump or turbo gasket. as when cold everthing is nicely sealed. once things heat up and start to expand your leak begins.

thanks guys.

Does anyone know where i can get cheeper turbo to dump and turbo to manifold gasktes.

Here in tas no one has these cheep, like $36 each.

wogs, it's all to do with the quality of the gasket material.

I'll give you an example. With aftermarket gaskets, say like the dump gasket, they're usually two pieces of thin foil with goo sandwitched between.

Those are pretty crap, and don't last that long. The crap in the middle can get blown out and it leaks.

The genuine nissan dump gasket/turbo to manifold gasket is a solid metal gasket. I think it's copper.

It's really hard work to do all the gaskets/studs. As 31nismoid said, it'll be 6-800 if you get a workshop to do it, and the same amont of work if you do it yourself.

That's why I always use genuine gaskets, coz I don't want to have to do it again.

Think of it this way, your nissan gaskets have lasted 10 year. If you do it now, it'll last another 10. That's not much in the scheme of things. If you use goo gaskets, they might blow in 2 years.

If the gasket material of the aftermarket gasket is good, then that's cool. use it. but check it. don't get it just coz it's chepaer

36 is cheap if it's genuine. Just jap sell the turbo to man gaskets for like $40-45 or something from memory.

second handis cheap, but I wouldn't do it.

Hi,

Can you hear the ticking pretty easily when standing next to the side of the car or do you actually have to be under or in the engine bay to hear it? Reason I ask as mine makes a ticking noise when cold but I notice it dissapears when hot. I noticed it after I changed to a different brand of oil. I went to Motul instead of Mobil 1

Cheers

you can hear it slightly if the bonnet is shut and standing next to the car, but if you put your head down, you can hear it easily.

I have also swithced to a different oil, however i do not think that is my problem. Time will tell.

[R31Nismoid]

Depends how perished the gasket is... as to how loud it is. There is no "set" loudness unfortunately.

Could be faint, could sound like 50 grandpa clocks all ticking

[smurf80]

Well mine was related to oil changed it an now all is sweet. Hope you fix your drama soon mate.

Well i hope it's not oil, i guess i could try that. I have 10-30 Fuchs in it now, fully synthetic oil.

I can't remember if it ticked mych before, so who knows.

I have a strange ticking noise when I give my car a little rev, dont think it's the injectors. On idle there is no ticking but if I rev it to say 2000rpm it's ticking while rev goes up. If I hold the rev at 2000 it doesn't tick. It's only there when I rev it

When you take the manifold off, you'll probably break studs.

Also, the manifold probably won't go back on, because the cast ones usually warp with the heat

Hey guys,

Sorry for the thread digging - but I like searching for past info then dump the same problems in new threads. I think I've got the same gasket problem mentioned here but need your guys advice!!

Anyway, I drove hard at Eastern Creek on friday - on the drive home out of nowhere I start hearing this noise - similar to what has been said in the above posts.

It's a ticking sound, pretty much coming solely from the turbo. Here's a vid I took.

The coilpack cover/turbo heat shield and other bits and pieces have been removed to specify the source of the noise, there usually in place normally.

What do you reckon? Gaskets?

[FloydWestwood]

Oh, I should also add

oil pressure remains fine, car feels very underpowered, still on stock boost, but I can get maybe around 5psi out of the turbo if i give it a real bootful (which I'm not really inclined to do)

Mods are:

3" turbo back

FMIC

Turbosmart boost tee

Stock ECU

[FloydWestwood]

I get a mad burning smell too.

[GTRsean]

Change tha damn gasket Floyd!!

It sounds like the manifold to turbo gasket has blown out a part of the gasket.

Replace with a new genuine nissan one and it'll be sweet!

Funny ticking noise from under the car?????? Could be a bomb!
