How do you do it? Do you have to make a blanking plate, or can you just pull the hoses off and block them?

Regards.

 

Looking at your model you will need a 32mm plug and a jubilee clip ... easy as that

 

But what about the little pipe that attaches to the top of the DV?

 

In the past to rule out dump valve issues when trying to locate boost problems I have cut a bit of plastic out from whatever I could find around (used an old oil bottle once) cut it to shape, made two holes for the bolts and then bolted it between the dump valve and intercooler. Not sure how long it would last for mind you but works as a tempory block off.

Cheers
