Nope,

At least I don't think so.  The engine/turbo has never been apart such that I could have possibly left out a critical piece.  At better than 140k miles, there's no question that a complete overhaul is in order, but, recent smoke aside, it just runs so damn great!  Not enough reason for a tear-down....

I thought about a turbo leak from the oil-supply line but couldn't figure out the mechanism for so much oil to be getting into the exhaust, especially only at certain idle-times:  Only after coming off an extended cruise or burst if speed, at full operating temp (180 as I recall), and the engine winds down to idle speed does the embarrassing smokescreen come up.  You should see all the dirt looks I get from those Prius-owners!

However, I recently found that if I can keep the rpm up over 1200 at stoplights and such, I can greatly minimize or even eliminate the smoke problem!  This technique, combined with fresh 10W40 oil, a can of STP and a can of Restore, I only generate about 1/3 the volume of smoke as I did last week in the worst-case scenario.  What's more, now the smoke is practically ALL BLUE, whereas before it was mostly WHITE... the difference between burning traditional, mineral-based oil vs. Red Line synthetic...?  Who knows, after another couple of weeks with these additives, I may even be able to reduce all smoking to no more than one of my favorite Jamaican cigars!  

Meanwhile, I ordered a set of new valve-stem seals from RockAuto and next week expect to replace at least the driver's-side bank of units (the easier-to-remove valve cover), which theoretically should reduce at least 50% of the smoke and maybe keep things stable enough for me to wait to get another vehicle running, tagged, and insured so that I can totally decommission Ol' Reliable Syclone #773 and start on its dream-motor... titanium rods and all!

Stay tuned,

D.O.

  Make sure you don't have a turbo seal out, they can real smoke alot.

  My 'Clone's valve guides and/or seals have had it and I gotta do something before the EPA-cops give me a ticket!  After coming to a stop at a light or sign-- once the oil warms up... even 5W50!-- after a cruise, I get ENVELOPED in a pillar of cloud that is reminiscent of Moses and the boys running around in the desert!  This problem just crept up on me during the past few months and I gotta do something fast.

  Naturally, for me, a simple valve-seal repair isn't good enough.  Here's my chance to pop-in my new injectors, convert to rollers, and maybe even swap the heads!  Anybody know anything about McCoy's "Stage 2" heads, now on sale for $495 (a pair or each?) and why they're so much cheaper than the Stage 1s?

  Anybody have any luck swapping-in ROLLER-ROCKERS, with new or reused pushrods, on a stock set of heads?  (I did a Crane-swap-out on my TTA many years ago-- Chevy self-centering units-- only to break 2 of 'em when my CPU or ignition system went berserk and misfired the whole engine and shredded my TCC....)

  Thanx in advance,

  D.O.
