I'm currently wrapping up a MK 3 Inno Cooper. Very nice and correct  car. Very early cars mid 64 and back had a breather vented toward the ground. The next generation had those large PCV valve mounted center of 309 twin 1 1/4" intake. The one I'm working on has had that intake port capped and the hose run down the side of the rad. I'd like to put the correct parts in and see how it does. Having done the 7.5 Cooper S brake upgrade all four corners as well as unleaded 295 cyl head update money may be tight here at the holiday season. 

I'd expect if a correct 998 Cooper your set up does not have breather ports in the carbs. Later 1 1/4 s do have ports and a connector to plumb. 

If I could suggest you invest in some books and do a little reading. I have a library at home and the shop with every mini book I have been able to find as well as a couple hundred mini and mini world mags. You will find books come in different printings I have all three of Vizard's Tuning and stacks of factory manuals. Just a thought Steve (CTR)

Anyone know if this is actually a PCV valve or ...........


Once the car gets warm under light load usually coming to a stop it makes a sort of squealing noise.
Not drive train related I'm 99% sure

Picture taking a balloon as a kid and letting the air out of it slowing.  that is what it sounds like. The noise comes from under the driver side fender. I noticed that the coolant Catch can was relocated under there. And attached to the can was a hose coming from this breather. 

Any ideas?

thanks

My golly!! That is an engine breather canister, NOT an oil breather, because the oil does not breathe, its the engine that needs breathing and de-pressurizing.

My mistake. Yes, on the back of the block.

I vote with MUR. Do almost anything but stick a little filter on the top. Although not the best answer, but still better than the filter, would be to run a hose down under the car. Usually you won't get the smell into the car, but you'd be dumping more stuff into the air that doesn't really need any more.

You can always hook that up to the crankcase vent port on the carb, or fit a pcv valve to the inlet manifold and put it there. You do not have to smell like car crankcase every time you drive your mini.

Thats for all the input guys

I learned to never overlook the simplistic solution today!

Was just a simple rotor disc baking plate rub!

All fixed now!

I will most likely just put a tiny k and N filter on top of the breather and let it be. It was originally plummed to the coolant catch can 
Dunno why

The blue can in the photo is a breather/vent. No moving parts like a PCV. Could it have been connected to an oil catch can rather than a coolant tank?

Connecting a line to the valve cover is not a good idea as it will not allow crankcase pressure to be reduced/vented (unless the VC is vented in a big way somehow). 

I don't recall what the factory set up would have been (early cars had a simple road draft tube pointed towards the ground) but ideally the breather/vent hose would be connected to a vacuum source to help draw out the crankcase pressure. Many just drop a K&N style filter on top of the vent and and another option is routing to ... a oil catch can.

It's the oil breather, although why they plumbed into the coolant catch tank is a mystery. Just put the hose up to the air filter housing or just pull the hose out of the tank and and let it breath to the road.

Mini's are like buses they come along in a bunch

It looks like a standard 998 tappet chest oil interceptor for the breather.
