What Is Blowby? Do I NEED A Catch Can? | R35 GTR [TECH NUGGET]
What is blow-by? If your catch can is full is it game over for your engine? Why do you even need a catch can?!

Andre runs us through these questions via the setup on an English Racing built R35 GTR from this year's Pikes Peak Airstrip Attack. We see this particular installation has the catch can in the boot with a simple drain fitting so that in the event of a catastrophic no oil will end up going under the tyres, and when everything is running as it should the team and quickly and easily empty the setup between runs.
