Here's the symptoms, tell me if you know what's going on.

Hard braking (100mph -> 10mph) downhill just before I get to the parking garage and shut her down. I come back out later and start the car and I get about 20 sec of dense blue oil smoke. After it clears up I'm fine and all's back to normal.

I had heard that the hard downhill braking is allowing oil to slosh forward under the rocker covers, into the PCV tubes and out into the airbox where it's then re-ingested through the throttle bodies and back into the combustion chambers. I mentioned this to my Viper tech a while back and he looked at the PCV and said he saw no evidence of this whatsoever. I'm sure it's something like this though ... I NEVER get it any other time except on startup right after that hard downhill brake. Where else could the oil be sloshing into the combustion chamber from?

I would have guessed that this would be the only reason for the blue smoke as well. He can look in the intake box and the crankcase ventilation system, but if it was only a little oil there wouldnt be much residue. Just my opinion.

Don't worry, it's normal.
Anything that creates G-forces will throw oil into reciprocating
parts in the crankcase - the result will be oil mist that finds its way
into the valve covers - and ultimately the PCV valve and intake.
Gravity is responsible for removing the oil build up from the valve train area,
anything that disturbs that also contributes to slow draining to the oil pan,
so G-forces and RPM create this and if it gets to be a problem, valve cover
baffles, crank scrapers(windage tray), can help - if not you might need
to plug your intake and vent the valve covers to the atmosphere. - But for
emissions inspection - you might need to be able to hook back up.

Its "normal". I'll take a pic of what I'm doing to fix this. Basically, I've rerouted some of the PCV hoses from the air box to a breather can. The breather can has two inputs and one output out the bottom. The bottom line then runs down back into the oil pan via a custom tapped plug.

After doing a couple lines I tested it at the track and I'm still getting oil puke so I'm about to send all the breather lines to the puke can. The only tubes coming out of my airbox will be the smooth tubes to the throttle bodies.

Believe it or not, at the track I was leaking oil out of my air box, thats how bad this problem can be!

Amazing that no one makes a puke can for the Viper after all this time. It must be a pervasive problem.

It happens to me often during hard acceleration on level ground. First time was at the drag strip at VOI7 and then again under hard acceleration on the "street".

Jason, why are you selling your car?
What are you going to replace it with?
A Modena?

I have many things on the horizon and have decided to TRY to sell some of my toys. I listed my HD VROD and my trailer on this site for sale. I will probably put my Cobra for sale soon too. I have some ideas of what I will do but not sure yet. Moving these comes first. I plan on picking up another GEN II Viper later and go another route with the mods though. Will you be making it to Texas for one or both of the shootouts?? One is in February and one at the end of March I believe.

No. Jason isn't allowed to buy a Modena!

you are right, Trey. Slow cars are not my thing, brother.
