Symptoms of a bad Metering Oil Pump
I first thought the turbos blew... But that's not the case, so I figured an oil seal went somewhere in the motor. Upon doing a little more reading, I found that a bad MOP can push too much oil into the motor. Anyone experienced a MOP failure?
Symptoms: Excessive smoke. All oil. So much, that it started seeping through the gaskets on the exhaust manifold and burning on it. That's it. No ECU code, no harsh idle, no loss of power, no low boost... just a James Bond smoke screen. Even after warmup. Smoke calmed down, but was still there, and very thick on boost.
Any help would be greatly appreciated!

The ECU will throw a code and put it into limp mode at first sign of a oil metering pump failure. The oil is likely to come from your turbos oil seal. It probably is blown and needs a rebuild. Why did you not figure your turbos were the culprit to the excessive smoke? Just reading, "when I get onto the boost, I get heavy smoke" that right there should tell you. Good luck. Try switching to a thicker oil if you are using 10w-30 to help with teh problem.

I will take a second look and see what I come up with. Thanks for the reply!

Sorry to hear about you car man, I wish i could help you, but other than turbos, i wouldn't know where to look.

Not sure the technical explanation but I left it disconnected by accident once and it did exactly what you described -plugged it back in and all was well.

Sorry for bringing up an old thread.
I have the same smoke problem. Lots of white/grey smoke from exhaust and some from around the turbos. Oil on the sparkplugs. Engine starts and runs ok, but smokes directly.
jdhuegel1: Did you solve the problem?
