if cam is necessary what would be a good mild cam to improve overall performance without losing too much in one area

I would talk to PRAY performance
or Texas speed. Once I hit 60k, I plan on doing a mild cam job along with whatever else needs to be addressed while the engine is apart.

I chewed thru it's first rear brakes at 24K miles. Shortly I get a letter about a lawsuit against Honda paying me for the repairs. Honda knew all of this but did they try to help --no. At 44K miles it roasted a spark plug. Didn't think much of it took it to the dealer and they replaced it. Then the service manager tells me a lot of the V6 motors are doing this. Few months later voila another lawsuit against Honda. Gets paid for again.

Now later on this blown spark plug is really a bigger problem of bad rings in the car. Voila another letter and another lawsuit. Honda extends the warranty to 8 years 120K miles because a lot of these motors have bad rings and the service manager once again tells me he would be happy to do the job as he has done many. Catch is you have to burn 1 qt of oil in 1K miles to get your motor done. Mine didn't do it so now I'm stuck with changing out that spark plug every 20K miles or so so that it doesn't foul when my wife is driving it as it is her car.

Now lets go my former '13 Honda Civic Si. Again I'm sure it was one of the greatest cars ever invented. If that car sits for 2 days or almost every morning in the winter it has this horrible squawk when you start it. Of course it is all over the internet and we believe it is the VVT acuators after the oil has drained out of it. Of course Honda doesn't fix it and I could leave it for a week and they say they don't hear the problem after I have shown them my own videos and they admit they can hear it. Of course I take the car home and sure enough it will do it the next morning. That car is now gone traded for my Camaro.

Long story short, people would have you believe that Honda Toyota, etc are better cars and they never have problems or they never break. Not really the truth at all and far from it!!!!

So up to you if you want to keep your Camaro but at least GM stepped up and I assure you that neither Honda nor Toyota will until they are sued.

Do I blame you for not buying a Chevy? Hell no I won't buy a BMW or a Honda and maybe a Toyota.

Exactly.

Chevy has put a lot of effort into this car and I appreciate that. Every manufacturer has issues with something and many seem to be worse vs GM as far as trying to deny warranty.

OP, I don't think a car with a bad motor is tainted. They are complicated mechanical devices and no car company has figured out how to make them completely reliable, especially performance models.

Yeah, videos are difficult to hear all of the nuances. I noticed the noise after going on a drive. I pulled into the garage and heard it amplified against the walls. Opened the hood and immediately knew it was not normal because it was only on one side and very pronounced metal on metal. Another tell was that it was barely audible when cold. As the oil heats up it gets louder. Never a good sign. The injectors dont care of the oil is hot or cold, they're always noisy because they're essentially little pumps hence their noise.

Tainted in that instead of a factory doing the assembly, it's going to be a dealership and their techs. From all of my experiences with various dealerships on various makes and models, I dont have a lot of confidence in them. I avoid dealerships whenever possible even for the simplest maintenance let alone an engine swap.

I'm just afraid that I'll be chasing issues. Plus, there is the stigma associated with "engine replaced at 2900 miles... like new otherwise" lol

I'm hoping for a buy back option.

You could just change lifters but why not change the cam and get some gains and a nice sound by the way? I'm guessing the warranty would still be toast even with non stock lifters. Might as well do the cam too. But then again, depending on lift, you'd also want higher performance valve springs and pushrods.

Thanks. I ended up at a dealership about 50 miles away because they specialize in Corvettes and Camaros. They didnt play the typical games especially when they realized I knew engines and showed up with a stethoscope. Lol and yes, mine is the harbor freight special! Lol doesn't need to be fancy, just a bit more comfy than sticking a screwdriver to my ear.

DFM uses all new hardware, and a pendulum torque converter.

2019 trucks ONLY. No Camaro application scheduled.

Dodge (MDS) has the same problem with their lifters.

At least Dodge doesn't put them in manual cars.

Thank God i have a manual , cause then i wouldn't have been able to modify anything on the motor. Cause i would have been paranoid about this issue. I wonder if the auto guys can remove AFM and use the valves from the manual

even manuals have the AFM lifters.

Are we 100% sure that they have them, or is this hearsay? Also, if AFM is not enabled in the manual, which we know to be true, would it matter if the lifters are present?

This has come up in numerous posts since the Gen 6 came out. And yes unfortunately the M6 LT1 engines have the same lifters (AFM lifters) as the A8 engines. The only difference is that in the engine software the AFM function is not enabled for the M6 engines. The concern is that the AFM lifters are potentially more prone to failure due to the extra complexity as compared to a standard hydraulic lifter. Why did GM do this? Its speculated that it is a cost savings measure for the assembly process as all the engines are built the same regardless of which transmission it ends up paired with.

[torqueaddict]

^^Interesting, thanks.

[DaveC113]

For those so inclined the AFM lifters should be able to be replaced without affecting warranty so long as the new lifters aren't the cause of a problem. Although, I'd probably only do this after warranty is out just to play it safe, but it seems like a good idea for folks past their warranty!

[torqueaddict]

I'd venture to guess the AFM lifters are more problematic on the cars with AFM enabled. And even then, there really hasn't been that many failures reported here.
