hey guys long time reader but never really posted because most of the answers are allready here. But this time i am at a loss. 94 blaster is using crank case oil and puffing white smoke. I read up and thought it was the crank seals. just installed both sides with cometic seals. I started it up and within 2 minutes idleing it used half of the site window. When trying to rev the motor it spits and pops. Any help for me guys.
