QuestionSometimes when I start the engine it makes blue smoke for a few seconds and then it stops smoking.Also I get check engine light on for a few seconds along with track off light and then it goes off.
AnswerIt's oil burning at start-up. It's more likely than anything else to be valve-stem seals. About $6 in parts, and hundreds of dollars in labor to change. During the process. Have all the valves checked & adjusted.
Call your local Lexus & Toyota dealers, and some independant mechanics that advertise working on imports like Toyota's, or Nissan's about replacing the valve stem seals & checking/adjusting the valves.
I will tell you flat out. Unless you like taking a leak in marbel lined bathrooms... If you need a dealer, go to Toyota, never Lexus.
If you don't have the money to repair it. Understand it *will* have to be done at some point in the future. Right now there are 32 little rings around the valve stems that keep oil from flowing out of the heads. They're just leaking tiny amounts of oil right now. It pools while the car sits enough for you to see smoke during start-up. After that, they don't leak fast enough to be a viible problem while the engine runs.
The seals are broken, and will continue to break. It wont' get better by adding things to the oil supply so don't even try. That will do nothing but upset the balance the oil is formulated too & accellerate wear on the rest of the engine.

Eventually they'll simply collapse & dump all your oil out into the intake & within maybe 10 minutes of running one day you'll have an engine with no oil in it.
It's just how every engine on the planet with over-head valves work. Nothing much I can tell you passed that.
If you can't afford to fix it now. Monitor your oil-consumption on a weekly basis. If it ever smokes for more than several seconds (Say 10 or 15) after start-up you're loosing oil & it *really* needs to be serviced.
**********************************
Your ECU is storing fault codes when your diagnostic lights (like the check engine light) come on. To get the code on the old systems, you jump TE1 & E1 in a DIAGNOSTIC port. Turn the key to ON & the CEL will flash the code in numerical fashion.
(Example:
Steady quick flashing is Test OK
3 quick flashes, pause 5 quick flashes would be code 35.
If it stores multiple codes. It will display them sequentually from the lowest number to the highest. And repeate them.)
