So i can't tell what is up with my turbo teg. After a hard day at the auto cross earlier this year, my car started making a faint tapping/fluttering sound only under throttle. It also only makes this sound when it is gear. It won't make the sound when the car is in neutral and the motor is revved. I can't tell if i have a valve train problem or if there is something broken with my turbo. my car is open down pipe, so it hard to tell exactly where the sound is coming from or what the sound is. Please help guys!!!

I forgot to mention, the higher in the RPMs i get, the faster the sound gets.

only makes noise in gear clutch out? ok either the trans is talking, or the turbo only makes noise under load.

kinda hard to diag this type of stuff over the internet.

Install cortemphttp://www.alcpu.com/CoreTemp/CoreTemp.zip on your laptop and see what your processor temp is. If it is over 70 degrees C, then you processor driver is not functioning correctly. If your processor driver isn't functioning correctly, reinstall them and the problem should be fixed. good luck!

Do you guys think its a a loose exhaust manifold gasket? It almost sounds like a piece of paper flapping in the wind.

could it be related to his blow off valve possibly a leak in the vacum line ? The reason i say this is it only occures under load not at idle ?

As a matter of fact, i know its very loose! either way, im off to start trouble shooting. wish me luck guys!

yeah change it back to the way you had it if it worked properly before.

Whiteintegra

ok, so i popped my hood and found 2 exhaust manifold bolts missing and 2 bolts from turbo to manifold missing.

Turns out that my bov was tightened all the way down. I'm going loosen it and/or add springs to it. Hopefully this will help.

im sure there's your problem fix it. use pneumatic tools

One of the ports for my exhaust manifold on my block has been stripped. How do i fix this?

Whiteintegra

I have a tap and die set, but im sketched about trying to use it on my block.
