ok on my 08 450 it started smokin last weekend and i cant figure out what the prob is. i did a comp check and it was holding steady so i dont see it being an internal engine prob i could be wrong. it runs fine just smoking i check the air box no oil and i found engine coolant in a breather valve below the crank case on the passenger side. could someone give me some advice? thanks in advance

In my experience blue smoke is oil in the cylinder. If it is on start up it may be valve guides which would still allow for a good compression test. There are many far more experienced motor guys on here that should be able to help narrow the problem down.

Have you checked for proper oil level?

it dont do it on start up but you can smell a little but its at high rpm atleast when i can see it. i have it on jacks in the garage and use a broom handle to push the gas to c when i can c it. if someone has any more ideas i am whiliing to give them i try. i have done compr, check breather tubes for cloggin, check reliefe valves to c if pressure is just backin up, i havent tore into the cam and piston because im not sure if it is that. thanks
