Found this product in an email from Minimania and don't know if there is something the same sold locally.

I still have problems with oil blowing out the breather on the tappet cover and maybe this would create a better breather - can be plumbed into a catch can sort of thing.

Hi miniDave..

I can't say I've used this product... How old is the motor? If you're getting enough blow by to necessitate another breather, it might be time for a rebuild. These things don't last forever after all,,,, and this product kind of looks like a patch more than a solution.

Dave, Give GR or the Doc a call, they should be able to point you in the right direction. Yours is only a fresh motor isn't it?

Your silliness has been noted.

You can make one using a breather of a tappet cover or similar, braze a tube into the side of it and braze the other end of the tube onto a plate to bolt onto the block. Someone might have a pic on one. Rather common and they fit under the exhaust with the right angle on them.

I adapted one like that when I first built my 1310. I bolted it to the fuel pump flange and plumbed it to a PCV valve, like on a Cooper S.
All went well until the motor was run in and I went up over 4500 rpm.
Then the crank and rods threw heaps of oil into it, and the car did a fair impression of JB007's smokescreen.
Might have worked if I'd put a baffle across the entry, but I fitted a flywheel housing one instead.
I'd try that MiniMania one, it appears to be baffled internally by the way it is made.

I had the same problem when i went to lakeside. The canister had mesh in it though so i put it down to excessive blowby because the bores have corrosion marks and slopy pistons.

After the first session at lakeside when i pulled in due to smokescreening i put all the breathers into my washer bottle. After 5 laps the washer bottle was half full and oil was EVERYWHERE in my engine bay, was even coming out of the vented oil cap.

Yes - the engine is fresh, just clocked up 1,000km. The breather I have on the rear is the one that looks like a shepherd crook that bends upwards and then drains down on top of the diff.

The rocker cover is one of those shiny aluminium ones and I have doubts if it vents well enough. I like the idea of maybe putting through a hole through the rear and adapting a tube into a breather.

I have noticed when the oil level is at the top mark that comes out quicker. The level now is between the two marks and after a blast the other day there was less oil drips on the bottom of the remote.

May be it is one of those things you just live with . . . but I really hate engines that leak oil.

Dave, I would fit a late Clubby 998 (same as Cooper S) breather canister in place of your `shepherd's crook', and I'd run it to the vac ports on your HS2 carbs (if they have them) otherwise to a PCV valve on the manifold.
A proper PCV system maintains a slight vacuum in the crankcase, = bingo less oil leaks.

it sure does.... my timing cover seal always weeped a bit of oil after my last rebuild, stopped the day after I put the PCV back on

I have 2 breathers into a sealed catch tank (90mm PVC pipe, plain cap at the bottom, screw on at the top) that is about 1.5l, and from there into the PCV. Means that if a bit of oil does get thrown out of the breathers, it won't go straight into the inlet manifold

would it be possible for a few oics of these mods, a picturs speaks a thousand words..

Pics, Pics, Pics....sorry, little fat fingers...LOL

Here is a photo a fuel pump engine breather that l have just installed on my 1380.

I haven't fitted the engine in yet. Will let you know how this breather runs later
