Yes power loss starts to happen around then.

Right now on the corvette forums we are in the process of proving it. Data will come soon.

My find post where I linked

That is a catch can by definition, whether you agree or not. While it may not be in the optimum place according to some, GM engineers wouldn't have added it if it wasn't going to help. I will still be adding an additional one, as I always run one.



That is incorrect, as multiple 2011 and later Z06's have had the issue, including the one my brother owned (a 2012).



Good post, and so true...



Now this is a man who makes sense...

The problem comes from the PCV , GM addressed the clean side. Which was never even that big of a problem. Just understand that. 95% of the problem comes from the PCV.

Not entirely true...as I've said, I've own multiple DI engines, how many have you owned?

Like I said, if you run top tier fuel, do regular oil changes with good oil and toss on a catch can you will be fine. depending on how much you drive, you may need to do a top end cleaning, which is not expensive or a big issue. On one car at 50K I had the top end cleaned for like $225...that is worth the price of admission if you ask me.

You just seen anti-DI no matter what the case, which is fine as we all can make choices, but you are tossing around some falsities that aren't true for all engines with DI.

But the main reason to get rid of the LT1 is direct injection. Direct injection is the worse thing to come out of the industry in the past 10 years. cars are needing manual cleaning at 40k miles.

Even when you put a catch can system on, carbon will happen over time. just not as fast.

the LS motors are built to last, and pull 10s.

That Stingray was a gentle breeze away from 9s.

Oh now I see the point about DI. Is it that bad?

Can't we inject some meth through the manifold if that worries us? Still much cheaper than a swap.

After having had 6 LS engined Chevys, I can say they were all very dependable and reasonably well powered, but the LT1 has all the power and torque you could possibly ask for. As far as I have read, there are no general failures of any of the engine's internals or peripherals. The simple thought of going backward with technology doesn't pass my "giggle test"! Bad, costly, unreasonable suggestion.

So I have to mod a emission control system just to keep the power I paid for ? What happens to the MILLIONS of cars that don't do this. All they do is follow the GM manual. Yet will see problems, is that fair to the people?

You guys are new the the LT1. We on the vette forum have been talking about this since 2013. There are a lot of professional shops and people saying these engines will have problems because of build up.

We have a thread created now to prove it. Data will come soon.

Build up that the owner let happen by:

1: Not running top tier gas. Many gas stations people think are top tier, are not.
2: Not doing proper oil changes. Meaning do not by the OLM.
3: Not installing a catch can.
4: Not getting the top end cleaned when needed.

Build up is something that can be prevented, or cleaned...simple as that.

This thread is stupid. That is all. Run whatever engine you want but leave your fear mongering about engine failures at the damn door. Whinge elsewhere.

ROFL so it's the owners fault for not installing a catch can!

So I have to mod my PCV (which is a federal crime) not to get build up!

What a joke Oh btw, top engine cleaners will do more harm than good. When Carbon breaks off the valve where do you think it goes ? When I get home I will get you more data on that.

No, but the other three points I made are. It's $100, anyone buying a car with an LT1 can afford that...

Oh please, you are are a car forum...hundreds of mods can make a car not CAFE compliment and such.

Not Sea Foam or some crap like that. Dealers have specific cleaning procedures for DI.

Why are you even here? You are a borderline troll, all you keep bringing up is this "data" which is coming from a car forum of all places. Sounds more to me like you are trying to get something from this "data" which you are directly involved with. It is pretty obvious you think you know more about DI then you actually do...and when you said this "Direct injection is the worse thing to come out of the industry in the past 10 years.", I knew that was the case...

On that note, think what you wish...I'm done wasting my time on this subject.

I am telling you if your valves have carbon on them, and you use a cleaner. Bits of carbon fall off and get stuck on the cats.

I am here because I own a car with a LT1 v8 engine. This engine had a lot of great things, and one bad thing.

I will leave now, and will return with my so called data. Probably few weeks
