You are right in that he puts his faith in the manufacturers designing a system that will meet emissions standards and last with minimal maintenance. Some engines may do this, others may not be designed as well. I think if manufacturers can get them to last the warranty period then that will be good enough for them. Not so much for us.

The other thing he points out is that if you remap or chip an engine it is likely to increase the crank case pressure so you get more blow by. He strongly recommends against this. The problem is that most people will seek to increase power, especially if the engine is underpowered for the weight of the car. A lot of diesel 4WD's do OK out of the show room but as soon as you add the weight in the form of accessories they no longer cope. This is what has happened in my case. I did all the touring mods and then found the engine (ZD30 CRD) couldn't cope which put me on the expensive path of searching for more power.

It's almost enough to send a guy back to petrol engines.
