![Arrow](https://ls1tech.com/forums/images/icons/icon2.gif)
Hey all, I'll post a video of the noise I'm experiencing in a bit...I gotta get in the car and drive it ![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)
However the most interesting part is...it sounds LOUD on a cold start and a rev...it pops like a popcorn machine
And now, my ABS InOp light is on...what the hell! I don't know if this is related however when I make left turns my back right tire sounds like a whining dog wanting food, if you catch my drift.
Any help would be verrrry much appreciated, I'll be sure to get that video up on here ASAP.

Edit, the ABS light only sometimes comes on after when I've been driving...
And I also noticed, there's a tiny little whine that keeps happening, almost sounds like a little robot is moving his arm...I can't remember what it is but I know it's only suppose to happen once then die off a few seconds after the car has been started then go away, it keeps turning off, then on, then off, then on....???
Here's the video of the popcorn machine and some nice ticking under the hood...

Popping from the exhaust at cold start is normal. It's a combination of cold metals in the engine creating too much clearance until they warm up. Also a car runs really rich at cold start to help the motor get to operating temperatures.

bang on you cat, see if it rattles.
for the ABS problem, when you first start your car the ABS unit goes through a self test, sometimes when one of the solenoids are bad or stuck it makes a loud noise that can be heard from inside the car. When the ABS light comes on it sets A DTC, If your OBDII Autozone may be able to check ABS codes, I'm not sure though. If your OBDI its going to coast some money to check it out.

Check your ABS Sensors. They're on the inside of the fender wells
I'm surprised also no one has mentioned the ticking being caused by an exhaust leak. Double check how well your manifolds are bolted in, and also if the gaskets are blown out.

I've done the intake mani gasket, but never a exhaust mani...and something tells me I'll be swearing and drowning my self in PB blaster for the rest of eternity.

$50 to have the EBCM codes pulled, which the shop I had taken it to promptly refunded once they pulled and cleared about 20 some codes and had the codes come right back up. They then refunded my $50 saying because they couldn't fix the trouble they wouldn't take the money paid on diagnosis.
I prompted for what might cause so many codes when it seems that the brakes work fine (when the light wasn't lit). The answer given was that they would assume it to be the EBCM itself, but couldn't be sure as they couldn't do a proper diagnosis with their equipment. I was told to take it to a dealership.
Bought a used EBCM for $35. (New ones are almost a grand). Been working perfectly ever since.
That's the route I would go.
Even if you figure the cost of the EBCM codes getting pulled, (which I'd bet most shop would charge you for even if they can't fix the trouble), I spent less than $100.
