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.

Why is gas coming out the Overflow not sure that I have the hoses hooked up right


They ARE backwards. You have two ******* on one side of the fuel pump and one on the other. Disconnect the fuel supply. The air hose is the breather hose from the valve chamber. The fuel pump works on pressure and vacuum. The single nipple is from the pump to the carb. The other two? Sherlock Holmes it and look at hose lengths.

2001 Kawasaki ZRX 1100 R gas in the crankcase


Hi, Tim, you're getting ready to go riding you pull out the dipstick to check your oil level and are greeted with the unmistakable smell of gasoline. What happens next depends on the following:
1. You have experienced this before and do not start the engine but do change your oil and filter leaving it 1 quart low until the engine reaches operating temperature then top off as necessary.
2. The amount of time your bike has been sitting, since the last time the engine was running.
3. The amount of gas and contaminants in the tank.
4. The oil pump location, exterior or interior.
5. The condition of your petcock gasket/seal/diaphragm.
If your gas tank was low and you start the engine probably nothing you would notice but if your gas tank was full and you start your engine the oil/gas mixture can blow into your air filter, come streaming out of your crankcase breather hose, and launch your oil tank cap followed by a blast of oil. The mess can be minor or you need to call a Hazmat team for assistance. This will also happen if you overfill your oil tank.
Next is the how and why gas can get into your oil tank/system:
a. The vacuum petcock rubber/diaphragm fails, which allows gas to flow from the fuel tank through the petcock, through the vacuum line into the intake manifold, then into the combustion chamber, where it seeps past the piston rings and into the bottom end.
3. Non-vacuum petcocks that are not turned to the off position will patiently wait until contaminants from the gas tank build up in between the carburetor needle and seat breaking the seal thus inviting gas to enter the combustion chamber eventually finding it's way into the bottom end and the oil tank.
4. Bottom line if you're not going to ride your bike for a while turn off the petcock.

1981 Honda CX 500 A blows smoke out of the exhaust


Hi, Anonymous your instrument gauges and lights can alert you to most electrical and engine issues they can not warn you about failed engine gaskets or seals so your engine has to resort to old fashion alert methods of colored "SMOKE SIGNALS" here is a breakdown of their meaning:
1. COLORLESS OR SLIGHTLY BLUE SMOKE on start-up means your air/fuel mixture is at the right composition and everything is well burnt in your combustion chamber.
2. BLUE SMOKE on startup is usually caused by failed valve seals dripping oil into the combustion chamber when the engine is not running.
3. YELLOW OR BROWNISH SMOKE at start-up means your air/fuel mixture is too lean. Too lean means that there is low fuel but high air mixture in your combustion chamber.
4. WHITE SMOKE on startup may be caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers. Smoke while riding is usually caused by worn out or damaged valves, seals, guides, pistons, rings, or cylinder walls.
5. BLACK SMOKE on startup is usually caused by too much fuel in the combustion chamber this can be due to air/fuel mixture adjustment too rich, accelerator pump improperly adjusted, faulty choke or not in the off position, air filter dirty and clogged, faulty carburetor float needle and seat, pilot jet too large, fuel injectors leaking, smoke while riding is usually caused by the main jet being too large or a damaged carburetor.
It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.

1996 Honda VT 1100 C2 Shadow Sabre oil in the air filter box


Hi, Wayne and the usual suspects are:
1. Oil tank/system overfilled.
2. Faulty breather valve.
3. Engine breather hose bent, pinched, kinked etc.
4. Air filter has too much "pre-oil".
5. Crankshaft seal failure allowing transmission fluid to migrate.
6. Blow by drain tube cracked/split or filled to capacity.

Model 331877 briggs fuel pump leaks oil out vent


I just got done repairing the very same engine with the same syptoms that you mentioned. I had considerable oil coming out of the fuel pump breather hole (copper colored mesh). The source of the problem: a blown head gasket. This will cause the piston, in the compression cycle, to pressurize the crankcase through the head gasket leak into the valve lifter chamber and push oil out the vacuum tube (bottom hose) leading to the fuel filter . To fix, you will need to first disassemble the cylinder head from the engine. To do that you first need to disconnect the three hoses to the fuel pump. Remove the cover to the air filter, remove the air filter and the screw in the bottom of the filter housing. Remove the four bolts attaching the plastic flywheel cover and remove the cover., remove the cylinder head (8 bolts)and check the head gasket to confirm it is blown (you will probably see some dark brown or black discoloration of the head gasket between the cylinder and valve lifter chamber. Carefully remove all old head gasket material from the block and head surfaces and clean the head bolts. If either your cylinder head or block surface looks ugly, you may need to get them resurfaced (flatness tolerance is very small ) Buy a valve gasket set (contains the head gasket and other needed parts)
Remove the valve rocker arm cover (4 bolts) from the head. Mark the exhaust and intake lifter rods (they are different) Clean the combustion chamber. If your engine has many hours on it, you will want to remove the valves and check the valve rims and seats for wear or pitting. You may want to hand lap the valves to insure they are seating perfectly.
I coated my head bolts with an anti-sieze valve lube compound. The B&S service manual calls for this. Reassemble head and torque head bolts to 220 in.-lbs. (4 stages) Do very accurately. Compress valve springs, install push rods and set clearances between rocker arm and end of valve stem. Turn flywheel to move piston so that both valves are closed before setting clearances. install a new fuel pump on the plastic flywheel housing. I removed the breather from the top of the engine (two small screws) and checked the reed and oil drain hole, and resealed the breather cover (you will need to pull the flywheel to get to one of the breather screws. I used a gray high-temp rtv liquid gasket compound to reseal the rocker arm cover and breather body. Reassemble all parts and screws and use small torques as listed in Briggs Service manual. I put in a new spark plug, changed the oil and filter, and breather tube, and o-ring at the bottom of my oil filler tube. That should do it

When turning the key to start the car,it just dumps gas into the air breather chamber .its as if the fuel pump continually is pumping fuel as long as you turn the key. its a 3.1 litre


Remove the oil filler cap, let some one turn over the engine and see wetter or not the valves are moving up and down, you may have a broken timing belt!

Oil in air breather


sounds like you have too much oil in the engine (should normally be around 500-600ml when there is too much oil, it gets past the piston rings and pushes it through to the head.
