Took off an elderbrock intakemanifold and put on a stock intakemanifold.

Now that i turn it on it makes a loud whistling noise but can't find itfrom where.

Checked all the vacuumhoses andtheyre ok.

...Any help is greatly appreciated... thanks

you might have a crack in the gasket or they surfaces aren't mating up well. thats my guess

use some carb cleaner to find the leak

dimebag

can i ask why you went back to stock?

Because ihave to take it to state referee smogging station for a ticket that i got.

Sucks because i thought elderbrock was going to send me a sticker of an e.o. # for the part number 3820to not change the intakeand they send me a paper listing ofall the other elderbrock intakes except the one i have.

So I just changed it.

I just finished putting it back on it was aligned right. Thanks for the help everyone

check to make sure your pcv valve is in

make sure your upper and lower intake are tightened down good together(where they meet)
