2018 Prado GXL and Catch Can

[xclusive]

Bought a 2018 Prado GXL with about 60k km on it. Planning to install a Catch Can as I've heard it helps engine in the long run. I've also been told these are modern cars so don't worry about it. 

So, would like to know:

• Should I install one now or later or don't need to
• Have you installed one and has it made any difference

Thanks in advance.

Old thread, but what the heck ....

Yes, fit a quality well designed (meaning not a cheapie) catch can like the Provent 200.  The VERY reason a catch can is needed is because it is a "modern" diesel, where the ERG valve is directing recycled exhaust back into the intake manifold which intersect with the positive crankcase fumes that are entering the intake manifold (via the turbo charger - intercooler - throttle body).  The result of this oily intake air hitting hot exhaust gas creates a massive buildup of oily black sludge in the throttle body and intake manifold.

Perhaps not a big deal for simple on road driving, but certainly an issue if the motor has to work hard (and increased crankcase pressures)
