Oil in Air Filter

[MrBeard]

Hi guys n gals

T25 1.9 DG engine. 1986

We have isolated it to be oil coming from the Breather Housing and Breather Hose. There was more of a push than a suction from the hose with some oil vapour.

what can I do to repair this?

Cheers

Nothing it's quite normal
just ensure your breather hose is not kinked and the breather tower is not blocked

I am getting about an inch of oil in the air box and filter in about 2 months

normal?

It cant be good for the engine to have oil going from air filter to the carb and engine block etc..

One friend says I need to re-bore and re-ring the engine or replace the engine outright, hence my surprise with your sentence of normal.

I would be over the moon is this is not a real issue.

I can only comment on what you post...
Now you decide to divulge more specific information.

So now I can say it's not normal.

If your crank case is getting pressurised from combustion blowing past the rings, then your friend is correct, in his saying a re ring will be needed.
A dry cylinder pressure check, followed by a wet cylinder pressure check, will determine this.

Over filling with oil, I would think, produce oil in the airbox.
The breather tower collects/traps oil vapour and allows it to drip back into the engine, is this working OK.

when I bought my van nearly 3 years ago one of the first things I did was change oil and filter,air filter etc,when the airfilter was lifted out I noticed bit of oil in the bottom of the filter housing,I removed it degreased the whole assembly and refitted,have not had a drop of oil in it since,bone dry,is this ok??,she runs sweet as a nut,an excellent motor

kevtherev I apologise if I came off rude, I was just surprised.
I thought my initial was enough, but obviously I didn't.

Thank you for your patience.

I will try to get the cylinder pressure check done.

I am aware that it has been over filled with oil at some point before I owned it. and recently the dipstick can undone, so I may have also over filled it, before i realised the dipstick was not connected.

the breather hose has some oil residue in the tower end, and spits out a fine oily mist at the airbox end, does that help?
