This might explain your oil consumption and to a lesser degree the smoke. This type of driving tends to cause sludge build up which in turn can clog some of the smaller oil breathers and venting passages. Short distance combined with cold climate takes a toll on engine and transmissions as well as the cooling system since the fluids never get to operating temperature to burn off moisture but get warm enough to absorb it and keep it within the fluids to create sludge and cause rusting of cooling components. Take it on a nice long drive and keep the engine speed around 3500-4000 for a few minutes.
Now all you have to do is find a new mechanic who is both competent and honest.

If the smoke has been eliminated or subsided, I bet it's not sludge per se, but just oily build up on the catalytic converter. You need to get it nice and hot to get it to operate efficiently or it will clog and break. Long trips or sustained hard driving will get it hot.

They took the engine apart and took photos which were forwarded to Lexus along with recommendations. Calling Lexus today to see what they say. Only 73000 miles on it.

sportsmom - you have a 2002 just as i do, and i only have 60k miles. The oil gel settlement only provides for 8 years of protection from the original sales date. Didn't they deny your claim on that basis alone?
I have not bothered to take my vehicle to the dealership for just this reason. I'd be very interested in knowing that there is a way to get relief even though one's vehicle has exceeded the 8 year settlement period.

So Lexus finally said no and I am having trouble find a engine mechanic to even consider doing this job. I don't know if they can't handle or don't want to. Can you guys just give me a handle on what might need to be done. Why would sludge build up cause grey smoke? and why when it has been sitting for a while is when it is worse. Just need some ideas on how to nail down a few options and what have to be fixed or replaced. Thanks,, Toyota won't touch it says I have to go to Lexus. I took to 2 engine mechanics and both kinda backed down and didn't want to touch it. I guess more of a hassle than the money.

Yelp.com would probably be your best bet. Here's the top 8 mechs I found in your area.

Otherwise, do a search in the messageboards or just Google.

To get an idea of whats involved watch this video.
Hopefully sludge is apparent under one side only.
the grey smoke is from some of the sludge buildup behind the intake valve is pulled by the incoming air and dripped into the combustion chamber.

It's a thankless job for a mechanic because there is more crappy work involved than a regular engine rebuild estimated hours account for. You might be better off buying a rebuild engine than trying to rebuild yours. With the exception of the crank (may be), There is not whole lot parts than be salvaged from your motor.
