owners manual, or see the link.
where does the oil gush out from? but you obvioulsy either have a hole in crankcase, or oil pan, or the oil pan and gasket are loose
if it has a fluid view window, fill to cover window. if not, fill near top of fill hole. It cant hurt a thing having it full.
haha same on my cr125
Yes, you can fill in a hole, you can not fill out a hole
Your crankcase should hold a little under a quart of oil, but the exact amount is irrelevant beings there is a plug on the side of the case that will indicate when its full. Just unscrew the plug and fill it till oil starts coming out of the hole. Pretty simple.
Drill an appropriate sized hole in the end of the key and use a stud extractor. If that is not possible it is likely that you will simply have to cut it of and replace the flywheel
One possible cause is a blocked PCV (positive crankcase ventilation) valve. As your motor is running the crankcase will build with pressure and the PCV system will let the motor breathe. If the PCV valve is blocked or faulty then the motor will look to release the pressure somewhere else.
Most likely , depending on the condition of the engine, the piston rings are worn or full out bad. The purpose of the piston ring is to help seal the compression pressure in the cylinder. When they start to go bad the escaped pressure pressurizes the crankcase, and then vents anyway it can i.e. The oil fill hole.
Fill it till it runs out of the fill hole. Again that's the FILL HOLE, not the DRAIN HOLE. They are separate.
front or rear diffs take approximately 320cc. fill the diffs till the oil runs out the filler hole, it will find its own level.
The fill hole is located about half way up the rear differential, fill it to where you put the fluid in, there is no way to get any more oil into it then that and it will be at the right level, you can also drain it into a measuring cup to see the exact fill the factory put in.
The fill hole is the dipstick hole itself. You usually need a long funnel to get fluid into it, and it's slow to fill because of this.
