Urgent: Is this normal? (Picture)
Hello everyone,
Since about a month I've had serious overboost problems. Today I've checked the vacuum lines and I've noticed that this one is completely stopped with glue or I don't know what. Is it normal? Could it be the source of my problem?
Thanks for you help...
And sorry for my bad english

I would venture to say that any vacume hose that is stopped up with glue is not normal. All the hoses under the hood of my car have homes. Can you figure out where it goes?

That line goes to the temperature valve which opens at 136F, it is located under the manifold by the timing valve, which then goes under the manifold along the block to the bottom side of your throttle body. That glue you see is probally melted vacuum line. Check from the point in your picture all the way through the temp valve to your throttle body.

Jason: Thanks!
superjet.1: Here's my problem... my car often overboosts in 3rd-4th-5th gears. After repetitive overboosts, when I stop at a redlight and then try to launch it sometimes stalls once. I then start it back and everything is fine.
I'm running on stock chips and the boost gauge indicates 2 BAR at 4000 RPM or so. There is no visible boost enhancer. The problem is that I've owned the car for 2 years and the overboost problem only began 2 months ago without changing the boost. It had never happened before. It happens exactly since I've changed the fuel filter. I looked at the vaccum lines especially the ones around the cycling valve and everything looks ok.

Where is the wastegate located exactly? Does anybody have a picture showing its location? As you can see I'm trying to learn as much as possible about turboed cars. <img src="graemlins/crying.gif" border="0" alt="[crying]" />

do you have a aftermarket boost gauge? If not, i highly recommend because you could very well be running more than 2 bar boost...which is very unsafe on stock chips...
describe the overboost more...is it like hitting a brick wall and you have to turn off/start the car to get it to boost above .2 bar (boost, 1.2 bar absolute) on the gauge??
