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?

Thank You! & Good Luck.

SOURCE: 1999 VULCAN HAS OIL LEAKING

hi, sounds like the oil seal in the rocker cover has failed, remove the rocker cover and you will see a rubber seal, this seals the oil inside the cover, however when the seal fails around the spark plug hole, oil leaks into spark plug well and out of weep hole.

I was out of my car and it started raining that with flood and now I got water in my oil could it be From oil pan


No the oil pan is sealed,unless you had a major hole. But you would have also had a oil leak.Water in oil is a sign of either a intake gasket or head gasket leak.

Peugeot 207 1.4, small oil leak from underneath, added engine stop leak, how long before it stops leak?


oil leaks from underneath can come from front crank shaft seal --rear crank shaft seal --oil filter--sump gasket---power steering ---leaking rocker cover gaskets ---leaking oil pressure switch.--transmission seals. I suggest that you have the engine professionally cleaned and then put it on a hoist while running to see where the oil is from

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

You told me about part no 12329-415-000 spark plug drain washer can you tell me how to replace step by step and would i need new rocker cover gasket or can i use old one and when finished how tight do you...


hi, the rocker cover gasket can be reused if is not damaged in any way you may want to apply a small amount of sealent to it, when tightening the rocker coverbolts when you feel them stop use only a slight amount of pressure to tighten, as they tend to break when overtightened, i am not sure what part you refere to exactly but if you mean the ruber ring that fits in the rocker cover then this is a simple job, do you have oil leaking from the weep hole in the side of the cylinder head?this ring fitted to the rocker cover stops this,

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

Oil leaking from small hole in left side of cylinder head.only leaks after bike has been ridden.does not leak while in operation


the small hole is a drain hole from the spark plug recesses, so you may have a rocker cover leak.
Pull the tank off and have a look down the plug recesses and you should see where it is going
