GEN 2 Intermittent Smoke After Idle

Ooof! My bad. Don't have any of her cleaned up on my phone, but here she is when I was installing the BOV and 1st oil change. And no, its not lifted. Just on jack stands..View attachment 442794

Nice moto.

Thanks Johnny! It's an absolute RIOT on wheels. Lol

Jayzus! that’s all we need is more this Jen is better than that Jen. We’re one, big, happy, dysfunctional Raptor family here.


Despite the ribbing, you did the right thing by coming here to find info and if you didn’t get a good answer out of reading, that happens. Better to ask, especially since it’s a first turbo.

However, since it was an intro post and lacked the appropriate, required photographic proof that we’re actually talking to a Raptor owner here,

So... Pictures. Or we are forced to conclude that this is you:

( I can’t believe nobody’s caught this one yet. Must be all the gummy spam posts )

We’re trying to be better. Like the Gen 1 Raptor. Better.

Unfortunately it sounds like your turbo seals are leaking a bit . If you are not super meticulous with oil changes; or they can just plain give out. Its a ceramic seal that can wheep oil. You gotta pull the intake pipes from the turbo to look . You could also pull your hot side pipes to the intercooler . If theres a lot oil you’ll know the answer.

Thanks man. I will try to check them out this weekend. I figure hot side pipes will be more of a tell since it's downstream of the compressor, yeah? I will look for a good parts diagram or YouTube teardown video on them so I can see what's going on in there. Is it safe to say that if the turbine is leaking into the exhaust, then the compressor likely would be leaking too and leave residual oil in the intake/hot side piping?

Have you noticed that you have to add oil in between changes? Also what are your current OCI? Is it a used truck or you had since new?

I check fairly regularly. Especially since the first time I noticed the puff of smoke. I haven't had to add any oil to it between changes. It's maintained the level with any losses being negligible. I change the oil every 5-6k miles and use Penzoil Ultra Platinum. Here's a picture of what the catch can had in it when I changed the oil this past weekend. There wasn't much as far as volume goes though, just enough to cover the bottom of the catch can.

Idling builds up a ton of moisture in the exhaust. As it boils off it creates steam. Since the exhaust has carbon residue within the pipes, the water turns dark and creates a gray smoke that has a carbon odor.
