Is valve Coking covered under warranty?
Probably a stupid question, but the car I just picked up has 13X,XXX km on it, so still 3x,XXX km left on the power train warranty, the cars bone stock and I didn't know if carbon build up on the valves was a warranty thing or not... would they clean it under warranty? or am I stupid to ask this question lol

if the coking causes a cel and idle and stalling issue, for sure GM will cover it under warranty, in my opinion. Myers used to do a lot of them. Some service managers simply try the addtive crap which doesnt work. Bottom line the car must work properly and not stall, which is a characteristic of severe coking. The GM guys may be waking up to not stonewalling issues that can cause potentially dangerous situations.
google Ford Pony gas tanks.

^or just clean them every 50k or so.. thats pretty much my plan of attack, which should be maybe once every 3 years at this rate with the car barely getting driven

Some BMW owners were able to get a cleaning done under warranty. I'm not sure how. Clueless dealers?
Same solution is over on an e9x board.. PCV upgrade and cleaning at the same time, some even opt for an OCC as well.
After 40k miles, valves look nasty.

If it causes issues like misfires, I don't see any reason why it wouldn't be covered. The valves are part of the drivetrain. I realize dealers can be a pain, but I don't see how they could screw you on it if you have actual issues stemming from the coked valves.

Padlock mine had 32,000 on it when i cleaned them and they were bad. Good luck with the 50,000 mile thing. I think its just the way these motors go. I am kind of interested if the guys running meth on a 5th injector setup can keep them cleaner by putting it through the intake.

for me, yes. while in college I've been putting on about ~25-30k a year.. thankfully I've got other vehicles to drive to keep the miles off the SS.. only 15k a year on it so far under my ownership (with storing it as much as I can during the winter)

Problem is, "damage" would be already done from the start. Powell upgrade would be ideal right after cleaning.
Can't believe that kind of mileage in a year.. I'd be luck to get over 9k. I average 7-8.
If I owned my cobalt from new, it would still be a baby.
My mom's cavi is an 04 and has like 50k miles on it.
