What Is Blowby? Do I NEED A Catch Can? | R35 GTR [TECH NUGGET] - Duration: 3:05.
there's a common misconception that for any engine that tends to fill an oil
overflow catch-can this must mean that the engine is terminally damaged now
while of course there may be some truth in this we're going to find there every
engine naturally will breathe a little bit this is called blow by and it's the
combustion pressure escaping past the Rings making its way down into the
crankcase and then through the breather system into the catch can now this is
perfectly natural and even a freshly built engine will tend to have some
level of blow by what makes this worse as when we're talking about very high
boost drag engines the amount of blow by will naturally increase even if the
engine is in perfect health when any amount of blow by is present we're also
likely to find that the blow by gases will naturally draw oil vapor with them
from the crankcase and this is why we tend to find our oil catch cans do fill
up over time with oil now under normal circumstances this is no problem in a
normal engine bay mounted catch-can will adequately account of this when we're
talking about a very high power high boost drag engine though a lot more oil
vapor will be pulled through and then there's also the potential for something
to fail in the engine which will involve a lot more oil going through the
breather system now potentially if we're running a engine bay mounted catch-can
this could be catastrophic if the engine does fail this can result in a lot of
oil making its way into the catch can and the catch can overflowing if any of
this oil then makes its way underneath one of the tires this could result in
the driver losing control of the car so a novel approach that we can see in the
english racing built our 35 GT are behind me is that they've actually
mounted a catch can in the rear of the car in the boot area now this means that
all of the breather system needs to make its way through the car through the
cabin all the way to the back of the car and this is the large diameter line that
you can see making its way into the catch can so there's all of the blow-by
gases in the rear of the car and the advantage here is that if there is a
failure and the catch can does tend to overflow all of the oil is rearward of
the wheels this means that there's no chance of oil making its way underneath
tire now one of the common servicing jobs with this car or any high-powered
drag car is to drain that oil catch can between runs and this can be easily
achieved with the ball valve that we can see at the bottom of the catch can and
then this goes to a drain at the rear bumper this makes it really easy for the
team to drain any oil out of the catch can preparing the car for the next run
