Damage to catalyst, due to oil being forced down the exhaust. If you remove the crankcase access hex screw and start the motor , a lot of pressurized oil spews out. Water vapor enters the crankcase of all motors from the atmosphere, and as a by-product of combustion. There were not much stuff in the crankcase plug. If left unchecked, the carbon buildup can also lead to detonation. Too much or too little oil can also result in foaming the oil which makes your lubrication factor drop. They run enough for the pump pick up to grab oil and lubricate the engine but they run it low enough that the counterweights on the crank don't splash in the oil too much. Excessive blow-by can be caused by piston rings that are sticking in the bore. Re: Gas in crankcase oil Usually gas in the crankcase is due to trash in the carb. bottom side of the dipstick. If the crankcase pressure exceeds 0. In addition, recommended oil change intervals must be followed. If not, you may have gas in the oil as well.

Now all engines have some degree of blow by. Additionally, an improperly broken-in engine or one with dry, cracked piston seals can allow too much gas to leak past the pistons into the crankcase, generating dangerously high levels of pressure that can cause engine damage and failure. I did notice that there was a little oil at the bottom part of the seal. So I researched up on what could cause this and came up with that is due to excessive pressure in the crankcase due to bad valve stem seals, bad piston rings, lack of oil (which is not the case) and or it could also be a bad oil pump (not very common). If there is a buildup of oil on the deck of the mower, around the tube’s connection to the engine or on the tube itself, the tube may be cracked or its seal with the engine may be worn. While gear oil will work, you can run a lighter weight oil in there. I though that Yamaha had a diferent case oil for the 2-strokes. Remove the vehicle from the chassis dynamometer. This specification was developed after testing multiple good known engines, VAG does not supply a crankcase vacuum specification. Smoking (blue smoke) due to oil above turbo oil return line (turbocharged engines). High crankcase pressures and oil leaks are a sign of head gasket failure, you may also hear a slight puffing noise as compression escapes from the cylinder. With the oil pan plug out, kick the engine over a few times to pump out the remaining oil; Lastly, remove the oil filter housing. The amount of oil should be between the upper and lower limits of the dipstick. Improper type of oil. Leaking valve seals result in blue-gray exhaust smoke. Both intake and exhaust valve are equipped with these seal and when they wear or get over heated they can allow too much oil to travel down into the combustion chamber much like when the cylinder head drain back hole plug up.
