The internet seems convinced that GM's lifter design is flawed, but I'd like to play devils advocate.
I am a prospective 5.3L Ecotec buyer and was wondering if the route cause of Afm/dfm failure could be lack of maintenance versus a design flaw. To my understanding the system works off of oil pressure and the fact that these engines are known for burning oil makes me think people are starving the engine of oil, leading to valvetrain failure. Carbon build up probably plays a role too. I'd especially like to hear from GM techs in case they have insider information. I could sure tell you some shit about Toyotas😉 Thank you.
I apologize in advance if a thread for this exists, I found something about the lifters turning in their plastic trays. But I'm not convinced.
