Crank engine crank case too full and gear case section empty of o
Drained the oil the other day on my 08 450 exc and found a piece of seal in the oil as well as metal, when i removed to fill plug oil came rushing out as if it was too full, however i fill to specs every time, noticed the gearbox section empty.
Was wondering if there is a common prob on this model.
Engine made a strange wine before hand however still goes hard.

Re: Crank engine crank case too full and gear case...
Running with no oil in the gearbox means all new bearings and seals and all new gears and possibly shafts. If you found metal in the oil, the entire engine is contaminated and will need to be rebuilt: Crank, top end and all else. Your engine is self destructing due to lack of oil. Yes, it still goes hard - - - but not for long. Sorry.

This sounds like the crank seal, the engine doesnt have to be removed, in order to get to seal is like replacing the ttiming belt, and once in the timing belt i would replace the crank and cam seals, also do the timing belt, and maybe the waterpump, you will need to remove the crank pulley and then the timing covers then align timing marks for timing belt before ou remove it, with timing belt off the crank pulley then slides off the crankshaft and the seal is behind it, the cam shaft gear unbolts and the seal is behind the gear, once the gears are off then you will be able to remove the seals from the engine,heres a few diagrams to help. good luck and i hope this is helpful,
The gray color(if it's milky) may be water and may mean that your water pump seals are leaking. Check your radiator level, it should tell you. Be sure to replace both and check the waterpump shaft for corrosion in the seal area. If there is, replace the shaft, too, or the problem will occur again.
If you don't feel that you have water in the oil, it may be that your right crank seal is blown. This will pressurise the clutch and tranny area and likely blow oil some out of any place it can on the right side. If this is the case, the engine will have to be pulled and completely disassembled to replace your crank seals and possibly the main crank bearings.
Gearbox oil may be getting into the crank area. Check the oil in the crank, is it motor oil or two stroke oil? If it is motor oil then you will need to split the center case and clean/re-seal the case halves. Be sure to install new crank seals. New crank bearings? If 2 stroke oil, just put a cup of gas in the crank to thin the oil, rotate the crank a few times to mix gas and oil, then just tip the bike over to dump the mix out of the case. If the bike has an oil pump, see if you can lessen the stroke of the pump. If mixing 2 stroke oil in the gas tank, Be sure to use only 2 stroke engine oil at 32 to 1 ratio. That equals 4 ounces of oil to a gallon of gas.
Assuming little Johnny did not pour oil in the crank when no one was looking, you must figure that there is a bad seal on the case halves. Did you fail to use a liquid gasket when assembling the case halves? Dirt on a surface? Did you not put in new crank seals?
If able, can you " burn out" Johnny's oil by riding all day? Does more oil get in the crank? If Johnny is not the culprit then the engine will need to be torn down. The need is to find the sealing problem and then fix it.
