: Engine Shake?

I had the first drive in my V today in a stop-and-go environment. One thing I noticed is when the car is stopped you can feel the engine shaking. Is this normal? It isn't extreme but it can be felt and was noticed by my passenger. Also, when I turn the car off it shakes one time at the end. I'm not sure if this car has very stiff motormounts or if there is something actually wrong??

Thank you!

someone stick an aftermarket cam in your car while you were sleeping? :thumbsup:

If I do recall all LS6's I drove did the same. I don't think I've heard yet of any motor mount issues. Mine pops, backfires, sputters, coughs, and damn hear dies when I'm in stop and go - but my car is special :worship:

Probably the cam, they all do it! Does it feel like it needs a tune up? Not that we really have tune ups anymore but...if that's what it feels like, then it's totally normal! Wait until you get to the point that you need to go to MA meetings and you install a bigger cam like I am getting ready to do!

They all run like that. Someone on here explained it that it is just those 400 ponies trying to get out. Is your car new or used? If used you may have a blown motor mount which is fairly common. Just put the car up on a lift and look at the oil pan it will have a stain right below there the motor mount is.

Hey, don't sweat it. If you're not familiar with the LS6, it can seem weird. It is not only normal, but encouraged...

Yeah, totally normal. I posted the same question when I bought mine.

Somehow we find it normal for a $54K car to have a rough idle and turn off like a diesel....hmmmm. People here will tell you it's due to power but go drive an M5 or any AMG product with more horsepower and see if they do it. I find it rather/typical GM like to be honest. I love my V but this issue is embarrasing if you ask me.

As long as you always remember you're driving a GM and that all will not be perfect, you'll love the car. Fit and finish (internal of engine too) is no Benz or bimmer.

Sorry guys, had to vent :)

Keep in mind that this is coming from a guy who does like the 55's and the M5 and M6 and it is mainly because of the great power and speed but...keep this in mind also...the Benz and Bimmer is no Caddy, with an LS6 or LS2, either!!! for $50k less money on top of that!...THEY REALLY AINT NO CADDY!

Sorry guys, had to vent :)There is no issue. You act like GM didn't know it was going to shake. You act like it's a bad thing. It's a pushrod motor with a relatively wild cam. This engine and its derivatives have been around for over 50 years. In fact, if people buying this car know even a nipple of information about this car, they'll know it has a Corvette motor. And it's pretty common knowledge that these have a bit of shake.

YOU may think the shake is embarassing. YOU may think GM had to revert to dumb technology to make a fast luxury/sport sedan. YOU may think GM has to use "old world" technology to make a comparable car to the Germans. But the rest of us appreciate the affordability of the CTS-V and the luxury it provides, albeit at a lower price. The rest of us appreciate the embarassment that a previous Gen M5 or C55 AMG or S4 owner feel as we pull away. The rest of us enjoy the dumb American technology that burbles and shakes our way past them. That dumb American technology that the old M5's motor couldn't touch. That dumb American technology that the new M5 can beat with tons of exotic material and technology that puch the price tag up about $20G and isn't that much faster. The dumb American technology that Mercedes can only beat by using forced induction. The dumb American technology that Audi can only beat if they "borrow" sister company's, Lamborghini's, engines. At a $30G premium.

And guess what? If the new V gets the LS7, it'll just be more dumb American technology. But THAT dumb American technology will simply destroy every other sedan on the planet. Sorry you had to "settle" for a CTS-V. Hopefully you'll be able to afford something so much better and so much more expensive so you need not embrace us with your presence.

Sorry, just needed to vent.:zzloser:

Bimmers and Benzes don't use big, honkin' V8s with long overlap camshafts in them, either. Nor do they sound as good, or look as good as my CTS-V. When a Benz pulls up behind me, I can never tell if it's a $29k C230, or a $130k S55 AMG.

Pass on that, both literally and figuratively.

I thought I'd get some reaction with my reply to the orig. question. I do find it a bit odd that it shakes, that's all. Some of us use their cars for work and such and it just puts a bad light on the product. A customer of mine asked about the shake last week and was more or less turned off about Cadillac, making a snide remark that "it's typical of GM". Expalin all the reasons why it does it, no matter, it still shakes and that just ain't right in my book. Sure, I love a bit of a shake in my Saleen or SS but not in a $50K plus car.

BTW, both the M and AMG products make 350+hp cars using natural aspiration. I compare a C55 more to a V (than an M5) and that is a fast car too, no blower or turbo.....any holy S, it doesn't shake. I tend to think it also has something to do with refinement.

I do love my V but drive a bimmer for an extended period of time and the overall quality begins toshow. I know, then go buy one :bigroll:

It is a big pushrod motor. It is going to shake, period. Your customer's have to understand that once you stand on the throttle and it pushes them back in their seat.
If you want smooth, step right over to the STSV with a nice, smooth running Northstar. My wife loves hers (non V AWD)! If you want a man's car sit down, hold on and shut up!

I love that Cadillac made an M5 beater in a car at $50G.

If you think that it has something to do with refinement, then you just have no clue about engines. Is the C55 a pushrod? No. Is it as powerful as the V? No. Most people know what a blowoff valve sounds like because turbos have become more common over the past few years. I suggest you get yourself educated because there are millions out there who know why a hot cammed, pushrod engine shakes. To make statements that it has to do with refinement or that it's odd that it shakes and that it just ain't right in your book shows continued ignorance.

If you want to be ignorant among your clients, that's fine. Make your jokes about GM and have your fun. But if you're going to come here and spew about how YOU think GM is crude and unrefined, then you just alienate yourself and make yourself look dumb.

It's a hod rod cadillac - LS6. I love the instability at idle. With the cam profile that the LS6 uses, it's nothing short of a miracle that the idle is as smooth as it is. If you want a real smooth idle, you could always buy a Prius, it shuts off the engine when you stop. :)

That is definitely not a "vanity cam". At 110 LSA you will be shaking your teeth out. With the high duration, you will move your power band pretty high. A good tune would be required. Good thing is the low lift. You wouldn't need to worry about valve springs.

Personally, I would be thinking mid 220's duration with a 114 duration. More lope at a 112 LSA, but find a good tuner.
