Everyone will have their different opinion about it, normal as its not going to cause any problems short or long term, but its not right if that makes sense..You can either clean them which I have done, which made no difference or replace em..which is about $100 per cam...so $200 for a complete job..Your under CPO so you might be able to bitch about it enough and get ones but 9 chances out of 10 they'll just "clean" em. Take a video with your phone on a bone cold start so you have proof to back up your claim.
