uh oh... blue smoke.

[HIGHPSI]

I'm also hoping anyone that has had this issue that may have found the fix can shed some light. I not have this exact same blue smoke issue. I had the LMS o/r downpipes and Magnaflow all put on at the same time it was tuned. Last weekend I cut out the third cat and straight piped it. Only did it because I could hear rattling from it thinking the catalyst was loos and banging against the shell. I had no smoke issues until I removed the third cat. After talking with LMS about it they said these cars are smokers after all cats are removed. I just can't believe so much oil getting by can be normal. I'd like to hear if any people that have o/r downpipes and third cat delete that have no issues. If there are people out there with no blue smoke issues it tells me it's got to be a common turbo issue most likely.

The common thread in all he smokey posts seems to be removing cats..... Everything else not withstanding, this is where it points.
Just saying....

Has anyone found if it's the lack of pressure on the seals that causes the leak or if it's just the nature of these turbos to leak and we just don't see it with the cats on.

That's exactly what I'd like to know.

Anyone that has deleted all three cats and has not had blue smoke and burning oil smell please let us know.

Everyone experiencing any smoke, did you have the oil return lines updated via the TSB or are you on the original un-updated lines?

I'm currently beta testing a resolution on my whip.

Final results still pending, however initial observations are look'n good.

Part of the issue, from what I've learned, is that the OEM supply side designed by FMC is dumping an unneccesary amount of oil on the supply side, into the turbo(s). This done purposely from what I understand,  to provide an adverse amount of safety to compensate for a (potential) range of conditions.

A light amount of smoke occurs when one chooses to go completely catless.

Regardless of what turbo(s) are being utilized. Stock, or aftermarket.

I'll digress for now, as final results are not in.

That's what I've been thinking of actually, it seems as if the problem is delivery of oil to/from the turbo. In my opinion, in order to have efficient delivery of oil you need a closed, air-tight system as it is pressurized to delivery the oil. FMC faulty oil-return lines probably were either too small or not creating a tight seal and causing some oil to leak out (reason for the TSB).

As such, having poor oil flow to/from the turbo's could result in fried seals (which some people are seeing) or inconsistent blue smoking from the oil being burnt.

Thoughts on this?

Any updates on this issue yet?

Its excessive oil flow that causes the seals to fail...

Our vehicles as many as of you are aware when purchased new or adding a upgraded turbo must be broken in properly,first couple hundred miles must be driven briefly and then to make sure to let it cool down,if procedure is not followed the seals can lead to heat exposure and cause abrupt consequences.
