My truck began smoking heavily in the last few days. I assumed it was bad fuel so I ran the tank near empty and filled up at my normal location (I was out of town travelling for the last tank). It still smokes. Mainly at idle and upon acceleration off idle, it'll spew thick heavy whitish blueish smoke. I checked the oil and it's a quart low, but I haven't checked it in a while... approaching 3k miles I assume.
Any ideas? What would cause it to burn oil. I do have a bypass oil filter that returns to the valvetrain area, perhaps I have a bad valve seal and it's leaking there?
