I've nearly achieved the impossible!!

After curing the major ones I have 1 source of oil leakage left now...just wondering if anyone can advise on this last one?

It's coming out of the oil breather pipe where it exits underneath the car.
It's only 1 or 2 drips a day, so nothing too major...but i'd love to cure it if possible.
I've not overfilled it with oil or anything, so i've no idea why it does this.
Any tips?

maybe a breather kit might do the trick to reduce?

like the full kit that vents rocker covers as well as normal to reduce/prevent. Maybe... like the empi one. i dunno.

But anyways, its when ur piston rings aren't sealing as much as they should, in turn combustion chamber pressures leak (or blow by the pistons) into the bottom end. This pressure then vents via the breather tube.

Chris is right me thinks.
getting a breather box and venting the valve covers would fix this.... most likely. but if you do have blowby, check your oil regulary.!!!
to run this breather box, you will most likely need to pick up a different oil filler also 🙂

if its a stock engine then the stock breather is sufficient. getting and after market breather kit with a catch can might fix the leak but its only a bandaid.

if u want to fix blow by then rebuild the top end. other wise id just live with the 2 drops a day. an after market breather on a stock 1200? is kinda rediculous.

Ok - my be wrong

Dont only the early oil filler / breather set ups have the drip tube??

Later 1600's dont have them

Cant (or didnt they) have a rubber cap to stop the drips and you empty it every now and then??

theres a little cap that goes on the end of the drip tube that acts like a one way valve to stop the engine sucking in dust through the drip tube during the vacuum of starting the engine.

u can get them from classic or micks or vintage

i gotta agree with nick, a vented breather setup on a 1200 is a bit of a joke

on stock to mild engines they're just a waste of time and money
i had a full vented bugpack setup on my old high compression 1835 engine and even on it i ended up removing it

it takes a hell of a alot of blow by to force it out the the breather, you would know if your engine was that sick especially a 1200

the rubber boot isnt gonna stop the leaks but it is needed as nick said to keep the shit out

if the engines healthy the usual reason they leak out the road draft tube is whoever assembled the engine puts the oil deflector/separator plate in facing the wrong direction

Thanks for the info Joel!
Only problem is, again, i have no idea what an oil deflector / separator is, so its not something i can say is fitted right or wrong!
Whereabouts is this part, and is it something that i can easily tell if it's been fitted wrong?
