My PCV and Lloyds timing wheel have been 100% since being installed by The Vic Shop in the Summer of 2013. I'm now considering the Maximus option. I'll have to remove the PCV, reinstall the oem timing wheel and also go back to using the O2 sensors. Removing the PCV seems straight forward as does reinstalling the oem timing wheel. But, what real world difference / improvement would Maximus offer that I don't enjoy now? It's a lot of money to spend and I'd want to ensure it makes sense to do so. Sure, a PCV can fail. So can anything else.
