SOURCE: oil leaks from breather box

Hi!
From your brief description It sounds like you are experiencing Crank Case pressure build up.
I presume your ZZR is of High mileage or possibly previous owners havn't serviced it regularly.
The problem being the compression Piston Rings wear and allow Blow Back gasses into the crank case there by building up pressure, this in turn sends an oil film up the breather tube to your air box resulting in your problem.
You could try an oil & filter change (Synthetic) Top jolly with maybe an additive plus similar for the fuel i.e. Red-Ex or similar, it may help but I doubt a cure.
If you want you could extend the breather pipe away from the box into a drip can or similar, be sure to filter it as you don't want to get contamination down in the cases.
Hope this sorts it for you?
Please press the Blue Button for appraisal of my FREE! Effort.
Thank You! & Good Luck.

SOURCE: oil leaking through the air breather. oil is

Just a possibility, i found this worked on some cars with similar problem (at least reduced the amount of oil going up the pipe)

Add a (bit at a time) bottle of STP oil treatment, the thick gooey stuff, it should increase the surface tension of the oil, keeping it in one piece, not splitting up and splattering around --> thus being less readily exhaled up the blow-off pipe.
just a thought. this will also increase the compression a little since it thickens the oil, will take up a little wear too coz it likes to cling on to bearings.

I have a Harley Triglide w/103 engine. After warm-up steam or exhaust comes out the injector body. Shortly after oil seeps out as well. Is this a breather gear issue?


Hi, Gary oil leaking from your air cleaner is caused by oil carryover from the engine. For whatever reason, the breather system is not separating enough oil mist and air from the piston downstroke. There are cheap and quick easy fixes and there are more expensive ones. First, make sure your breather hoses are not dry and cracked if they are ok you can start by trying the following:
1. Run your oil level half way between the add and full mark when hot.
2. Run oil breather lines from the head into a TEE fitting below carb/induction module then a single line into a mini filter under the frame.
3. Purchase Arlen Ness Super Sucker.
4. Replace umbrella valves and realign oil pump.
5. Upgrade oil pump and cam plate.

if its a 4 stroke and its the breather pipe then your getting pressure build up , what colour is the smoke , white or blue ? white is water and blue is oil ! water could be a seal or gasket leak , oil could be valve seals or stems or compression leak !

Volvo v50 t5 oil leak


Most likely it is the breather tube and/or the oil trap box (integrated into the oil filter housing). if the box is plugged or the diaphragm is torn the box will send oil to the top of the engine via the hose.

do you also have a high pitched whistling noise?

Volvo has extended the warranty for the oil trap box (filter housing) to 120k miles and/or 10 years.

VOLVO V50 OIL ON CAMSHAFT COVER


I will try and simplify the problem. I have an oil leak, which I traced up the back of the engine to the cylinder head area.
When I removed the top plastic cover on top of the coil packs I found oil in every recess next to the coil packs. The crankcase breather pipe was also off. The source of the leak is not evident, but it is definetely above the cylinder head gasket area.

Oil leak


Rick, since 1994, Harley has used what we call a "head breather" system in that the crankcase breathers are located in the heads. This was done in an effort to reduce the amount of oil that gets into the air filter. In earlier case breather model engines, the oil would pour into the air filter if the bike had been sitting for a few months. Prior to that, the bike would "puke" what looked like a quart of oil on the ground below the bike when first started after a long period of sitting.

If you'll remove the air filter cover and element, you'll see that the large bolts that hold the breather onto the heads are hollow. Inside the rocker boxes, there are small rubber "umbrellas" that are opened and closed by crankcase pressure. These are designed to allow your engine to breathe without an excess of oil being blown out. Still even though this system is better, a little oil still gets into the air filter. You can either keep this cleaned out or you can replace the "head breather" systems with an aftermarket system that changes the location the system exhaust crankcase pressure from. Also, you can change the "umbrella" seal and put in new ones. It isn't that difficult to do on the front head. The rear head can be tricky since there isn't much room to get to the bolts to take the rocker box cover off. The umbrella seals are located in the center section of the rocker box cover.

Good Luck
Steve
