Is 2002 lexus es300 a non interference engine
The 2002 lexus es 300 has the 3.0L engine, which is non-interference. The later lexus es 330 has the 3.3L engine, which is an interference engine. The even later es350 has the 3.5 engine and is back to non-interference as well as having a timing chain rather than a belt. Hope this helps.

Some test should be about $25 and take about ten minutes once the car is up on the lift, after all it is just a diagnostic test to see if there any leaks. The car should be on the lift to check the EVAP piping all the way back to the tank. It is unlikely that the charcoal canister will need changing, they generally last longer than the car as they rarely wear out. The charcoal canister and the whole EVAP system merely absorbs fuel vapours rising of the fuel in the tank. When your engine is warmed up and doing more than 2,500 revs the EVAP purge and vent valves open to allow outside air to be drawn in through the canister to carry the small amount of trapped fuel vapour into the engine to be consumed as part of the normal fuel air mix. The computer normally commands the EVAP system to open and close the purge/vent valves check as part of an inbuilt leak detection protocol and has seen an anomaly, possibly the vent valve not closing properly. Once the nature of the leak is diagnosed it is matter of fixing it and it should not be an expensive or time consuming job. Take the car to other mechanics and get their opinion and guesstimates. Put it like this "would you smoke test my EVAP, fix the leak and clear the diagnostic trouble codes from my computer for $200 including taxes?" If the answer is no then ask how close they can get to this price.
