How was it running? Any other issues with the motor? How many hours? There are a few different things it could be. Burning excessive oil, oil getting past rings, etc. It may just be the that new oil you put in her. I would probably start by first draining that oil out and filling it back up with the stuff you were running before or another fully synthetic 10/40 or 15/50. I wouldn’t go heavier than 20/50. Another option is a good semi synthetic diesel oil like Rotella T4 15/40. Change oil and run it and see if that fixes the smoke issue. If not, then do a compression and or a leak/down test on the motor.

If you are truly worried that your motor is damaged then do the compression and leak down test first.

My first thought is that oil is probably too thick and is being sent up the crankcase breather and being sucked into the combustion chamber with the intake air.

Hell yeah imma change the oil 25w60 to 20w50 and put some oil stop leak if it smoke again what u think??

The only time i have had it smoke was when i filled it to full. Might check that first. I use the Rottela thinking 5w-40 but not sure. I have had good luck with it and is reasonable priced. Do a search there have been conversations on what oil everyone uses. Rich

Ayt tnkx man

 

[megacab48]

did that fix the problem?

I noticed if I fill over halfway in the sightglass that there's a slight lessening in power, and I will get a little smoke on my 450xc. I remember posts when I first got it stating the same.

Definitely check the level. I run 10-50 amsoil. A lot of woods running, I saw cooler temps after switching. The 10-50 also is easier cranking than the 20-50 I ran before, which was also lower temps than the 10-40 prepreviously.

Me di cuenta de que si lleno la mirilla hasta la mitad hay una ligera disminución en la potencia y obtendré un poco de humo en mi 450xc. Recuerdo publicaciones cuando lo recibí por primera vez diciendo lo mismo.

Definitivamente revisa el nivel. Corro 10-50 amsoil. Mucho bosque corriendo, vi temperaturas más frías después de cambiar. El 10-50 también es más fácil de arrancar que el 20-50 que corrí antes, que también tenía temperaturas más bajas que el 10-40 anterior.

Benos días amigos bueno yo tengo un 525 xc con un poco pistón a 97 mm con 12.5:1 de compresión y árbol de leva +1 bueno hice todo esto porque mi motor se había perdido compresión y usaba 10w 40 sintético.. cada vez q le hacía el cambio de aceite encontré más residuos de metal en los filtros y luego q desarme el motor y hice está modificaciones desidia cambiar mi aceite a un 20w 50 mineral y los cambios en el motor han Sido exelente no he tenido más desgaste ni reciduos en los filtros si he notado q el aceite cuando lo cambio sale es más oscuros pero eso es causa de q es mineral... Hice este cambio porq acá en panamá el clima es muy caliente lo q ago pues s cuando arranco espero unos 3 minutos el motor en baja y me doy unos 5 minutos rodando la suave hasta q le empieze a dar más gas y gas gas por lo tanto he tenido mejores beneficios

I'd think you overfilled it or it just doesn't like that oil that's pretty thick
