Can Anyone Identify This Please (Rover V8 Engine)
I have no idea what this inlet/outlet at the rear of the engine does? Can anyone help please?
Cheers
Scotty

Its just a cam cover breather, most of the work is done by the rocker cover breathers, on EFI engines it does not even exist so you can just block up
if annoying you.
Failing that a little rubber tube and take it into the air filter base plate, it would have gone to the big back air filter housing that joined the SU
inlets after the U bends.

Thanks guys! I already have the rocker cover breathers linked into the carb vacuum port so I'll just block this little fella up!

Connect to your rocker breathers. but I would bother if both rocckers are connected ther are enough holes between the vally and rocker covers for the
carbs to suck the fumes out. IMHO

It is crnakcase breather. Originally it wold have been connected to the air cleaner so that filter air is drawn in. Most after market set up do not
allow for this hence you fit a wee K&N type breather, like this:
It should not be sealed as bad things will happen (I need to wrack my bran what that is; I also seem to recall that later engines did not have the
breather so it may not be that bad.)

It should be a tight fit, but seriously just bung the hole up, it is not needed and you do not want dirt creeping in there.
You have plenty of air gaps by the pushrods to allow air to get to the top of the engine, the only time I have ever seen a problem with a RV8
overpressuring was on an efi engine, all the breathers went to the front of the plenum before the butterfly into a 1/2inch tube, this was bunged up
with black goo.
The ali plate then buckled and leaked, before this the dip stick started to rise with the pressure.
On an EFI
* you do not have this tube.
* You only have an extraction breather on one rocker cover
* You have a tiny filter, usually broken and blocked on the other
As a carb engine you will have proper breathers on both covers, these would have plugged directly to the carbs, now they are probally sent to the
outside world, so already double the capacity of later engines.
