6 years and 1/4 million kilometres on my GM LNF DI, never had a catch can or walnut blasting. I'm sure coking is developing slowly but I haven't noticed any negitive effects so far. Still get my normal 28-31mpg daily driving.

Too many people baby these engines, which always results in more blow by and reduced compression I've seen it time and time again "do it like the book says" - wrong - ALL engines need a relatively aggressive break in, and it needs to be done quickly |

The one on my jet ski is actually much larger, forced induction motors always have more blow by |

Here is my question, maybe I missed it, what could be the harm of a catch can?
The OP stated you could be denied warranty claims for having one. GM bought my ZL1 with a catch can back for Stabiltrac problems, definitely not related, but GM or the dealer never mentioned it. In 3,000 miles I have caught maybe 3-4 oz in my '16 SS. Is this typical?

There is no harm, it's just that it is not "factory or dealer installed" that they could use against you if they wanted to. All comes down to your dealer. If anything, they should be glad you care enough about your car to have one...

I would say most dealers are not like that. Know your dealer before you buy your car. Some are very cool about addon stuff. Ask about those things you want to do before you buy.

Hearing this from a manufacturer who makes parts to fix the problem is liking asking a supplement company to give credible advice as to if their products work when the FDA doesn't regulate their products. You are selling a part that voids the warranty. If chevy has indeed made an engine that blows up before I get my 2-3 years out of the car I will just buy a Nissan or Porsche next time I want a sports car. I have no doubt your catch can collects oil, but maybe that's part of your design. I am sure if it is a big enough problem, it will be addressed. |

Once your engine blows, a GM rep gets involved. The GM rep doesn't sell cars, he is here to see what/why something went wrong. Your dealership (or your boy who works at the dealership) is at the mercy of GM. Now with aftermarket parts install, GM doesn't know the effects of such parts. For all they know you installed it wrong, and its causing damage to your engine. Its not there job to know how aftermarket parts should be installed, or the effects of them. The fact is you could have warranty problems IF your need a major engine repair and GM doesn't like your catch can. Most people dont have major failures, so most people are not reporting warranty problems with catch cans. |
