Rattle from Nytro engine when you let off

[dcorliss]

Rev it up, just before it revs down to an idle, a rattle sound comes from the engine. What the F***. Stage 1 S/C.

Ah,,,it's prolly just a rod bearing getting ready to let go,,,how much boost,,,what's your AF meter read?

From what I've been reading, you might want to see if your pulley is loose

 

[carbondaddy]

Maybe it's your primary clutch

Maybe it's your primary clutch

Yep, the primary does rattle a small amount.

Mine was doing that at idle...and when I shut it off. Checked lower pully...I destroyed taper lock and it was loose.

Thanks again for the reply's, My great, all knowing dealer, called right away as soon as he seen this thread, called me directly on my cell. Told me it was my blow off valve chattering. He says it sounds just like a steel rattle for a second. Boy I feel stupid, that is what it was. Thanks everyone again. Thanks for great service!!!! SHAD.

What lucky part of the snowy world do you live in where your dealer reads snowest and calls you to tell you what's up? Lucky...
