Oil Level Low!!! Help

[ff_jeff]

OK truck started to smoke a little a few days after the cam swap. I have been thinking its fuel. Started it up today at work, been sitting for about 2 days. Lots of smoke. I smelled like fuel, but after I let it idle for about 20 mins it was still smoking a little. I turned it off, then started it again. Low oil light came on. checked dip stick... yep... way low.
Im thinking its been burning oil this whole time. But whats weird is I checked the oil before I went to the track and it was fine. checked it the next day after the track... fine. It still smoked, but not as much as recently.
Yall think it might be the valve seals? Im at a loss for words right now. Looks like I have to cancel the dyno tune.
Help please!!!
here are the plugs
All were fouled by oil. some were loose enough to remove by hand.

If it's valve guide seals, you'll notice it most when there is no load on the engine. IOW, high vacuum. Try this to confirm: With someone driving behind your truck to observe, accelerate hard to about 4500 RPM in a low gear and then let off the gas pedal and coast. If you have leaking guide seals, the smoke will pretty much stop when accelerating and be the worst when coasting. This works the best if you can stay in the same gear.

Hopefully valve seals. Did you change springs, etc. when the cam went in?

If all the plugs are like that I'm going to say that it looks like it's drinking oil through the PCV system. I can't imagine that ALL of the valve seals are bad. Pull off your throttle body and see if there is oil all over the inside of your intake manifold.

hopefully that 125 shot didnt damage your rings.

Dude its toast go ahead and buy an LSX 454 and be done with with it.






JK I bet its drinking oil from the PCV like thunder said.

Jeff wasnt your AFR messed up when you got your cam in? Could this have torched your rings and causing blow by?

jeff i know this may sound stupid but if you changed valve seals did you seat them back down? i forgot to do that, my fault, and thats what my plugs looked like when i pulled them out for that problem and it was eating about a quart of oil every 600 miles or so.

You were correct sir. I had about 1/2 a cup of oil inside my intake. Got another breather for the driver side, cleaned up the mess... runs good now.
