i have a 1990 f-250 with a 302 efi the problem im having is there is alot of oil and blue hazy smoke going in my air box only wile reving or accelerating i was wondering if any one has had a problem like this or knew what was causing it

 

When I start my truck up on cold mornings it lets out a big blue puff if I rev it, but it only does it once.
Check and see if your oil smells like gas. you could have a bad ring and it's making it smoke. Does it get worse as you rev it up, or does it kind of clear out as you rev it?

 

it gets worse and worse the more i rev it I think it has to much crank case pressure it doesnt really smoke to bad out the pipe

 

it has fresh oil and doesnt smell like gas
