Ok, I still have a higher vacuum than normal, and coming out of my cone filter I still hear the muffled whoosh,whoosh, whoosh (kinda hard to explain). Anyways I got under the car and checked the BPV..All connections are fine. I checked the T i made for my boost guage, fine no leaks. So i have my friend get in the car and rev it while I stand under the hood. Now there is almost a constant banging/rattling noise coming from right under the block. My friend suggested possibly the water pump. I really need some help/suggestions guys.

01, 1.8t, 46,500 miles, Bailey BPV, Custom Intake..thats about it for under the hood.

the MUFFLED whoosh is because it used to be nice and crisp before. And since my vacuum is running around 10 instead of 20 i just figured it may have been something else. We'll see though. Anyone else with ideas would be appreciated.

Yeah, im going to, but what would account for that pinging noise I'm hearing under the block?

Nope it doesnt really do it at WOT, just when it settles back to idle.

intake i should check the connections again when i put the stock airbox back on 2morrow.

The 4 wires to the MAF to get it out because we didnt have the right tool to unscrew it
