sewing machine noise? Just wondering if this the same sound that people talk about after getting Long Tube headers installed?! Mine has the ticking sound after Pacesetters installed(and I do have restrictor plates put in if that matters). Just want some info on this. Thanks

I had a slight sewing machine noise after headers. It got a lot louder after the cam though.
Depending on how loud the tick is, it could also be an exhaust leak.

sounds like an exaust leak. Double check the headder bolts are torqued to spec and that none of your flanges are leaking. FYI seafoam makes it real easy to track down an exhaust leak

yeah true. I had my exhaust guy check for leaks and he said there wasnt any. I also had the dealership clean the car up and tighten header bolts if needed. So maybe its just loud ticking valvetrain noise.
Also how would the seafoam track it down?

Go to your local auto parts store, and ask them if they have any Sea Foam. It comes in a plain looking bottle, and has about a million uses listed on it.
Follow the directions on the bottle. Your brake booster line is the easiest way to get it in the intake.

I have a ticking noise that might sound the same. I have a sound clip that I created of it, but I do not know where to post it. Can someone tell me where I can post it? I want to see if this is the same noise some of you have.

Recalibrate? Nope. Ticking could be a lot of things, but if it goes away after warming up that could be an indication of piston slap which is plenty common in a stock LS1.

I read somewhere on here that you could use slightly shorter pushrods to reduce some preload on the lifters and make it a little bit less like a sewing machine. Is that correct?
