Clunking = Collapsed intercooloer pipe?
 
Could it be? im 90% sure i have a collapsed intercooler pipe somewhere and my motor seems to be "clunking" Could this be the cause?

also will 100watt fog lights work in a 55 watt housing?]

edit would a vaccume leak cause you to have little boost?

Not sure about the first one

Yes, although you might burn something or melt wires.

Yes

matt01 02-26-2010 01:43 PM

clunking could most likely be timing off?

boxpin 02-26-2010 02:07 PM

Clunking = not good.

you need to determine if its coming from the top of the bottom of the motor. Use a hose, PVC pipe or something that you can put on your ear and listen.

Legendsecko87 02-26-2010 03:56 PM

OH! it could be a spring seat mount.

matt01 02-26-2010 08:46 PM

no, its from the motor, you hear it when im ideling in driveway. i dont think its anything serious, but id like to do a compression test on it.

Would a boost leak cause it to clunk?

tech 02-26-2010 09:01 PM

A boost leak should not cause a clunk.

matt01 02-26-2010 09:07 PM

could bad wires or bad cap/rotor cause it, i just changed my timing belt but it clunked before that.
plugs are new.

91shelby 02-26-2010 09:18 PM

i doubt it, probably a mount of some sort

matt01 02-26-2010 10:48 PM

could be.
If the clunk really was the motor would i get a check engine?

tech 02-26-2010 10:52 PM

No you would not get a code.

matt01 02-27-2010 04:25 PM

anyways it probably is an engine mount, how many are there, upper and lower?

and the performance problem is probably a wastegate adjustment (i hope)

tech 02-27-2010 05:03 PM

You have 3 lower mounts and 2 upper mounts.

tech 02-27-2010 05:04 PM

Edit you also have 2 lower torque mounts from the tranny to the subframe.

matt01 02-28-2010 06:13 PM

how many of them are prone to knocking?

edit, does it happen often that wastegate loses adjustment?

tech 02-28-2010 09:46 PM

The R/S one will clunk if bad.

The WG will usually never go out of adjustment. It is usually someone that moves it.

matt01 02-28-2010 09:56 PM

my god i need a boost guage these POS GLT's/AWD dont come with one, so retarted that they didnt even come with the crappy cluster one, its not like the couldn't have easily bolted in a cluster off of a t5.

LOL I hear you

another quick off topic question, will a front door off of a sedan fit on my wagon?

edit: also my wastegate question... i dont have the time today to do it cause i work later, but i felt under the heat shield to the wastegate rod i though it was, and it seems completly loose, just by hand i could move it an inch in any direction.

tech 03-02-2010 09:10 PM

Pull the heat shield and inspect it.
I think so I would measure to double check.
