WOW! /\ /\ /\If the engine only smokes at cold start up the problem may be worn valves guide seals. It is possible to change these with the heads on but takes a while.

Probably a 96-97. I have a 95, and I've looked under the hood of a 96, and some vacuum lines are gone, such as the one for AC idle up and etc. The power steering vacuum lines appear to have changed as well. Not too sure about 98-99, but definitely not 2000+, because these have VVTi on them.WOW! /\ /\ /\
I think if it came down to this though, I would just swap engines, which leads me to ask - what's the lastest model Avy that I could rob a 1MZ engine from for my 1996?
Even though you have the same engine code, updates were done through the years.1mz's were in avalons, v6 camrys, and siennas, the latest you could get one from is from a 1999. in 2000 they changed the standard toyota v6 to i belive a 2mz. ive got a 1mz in my 98.
as the forum implies, our cars remained fairly unchanged from 1995-1999, engines and drivetrains included.
