Hey I bought my first diesel (02 chevy duramax) and it has some blow by out of the crank case breather tube. Is this normal for the lb7 engine to have it. Its about a quart in 4000 miles and of course I stand on it a lot.

I thought it probably was but to be honest I had no idea. It runs way good and has good power. If you pull the oil cap while its running nothing jumps out at you
