Hi Thanks for letting me join the forum,, PLEASE I NEED SOME HELP
Ive had a 2009 IS220d se for about 5 weeks , When i drive the car from cold ,no issues starting, after about 5 mins when it gets up to temperature ,it blows blue smoke out for about 30 secs then clears up,, continue to drive the car and about 5 mins later it blows smoke again and clears up. Ive had the car to a local mechanic,,had the car on diagnostics with no faults ,forced a regen, no luck,then he thought the car had been overfilled with oil,,then he changed air filter,oil ,oil filter, .. The car continued to sporadically smoke.. Back to garage again , he checked the turbo,found little wear but nothing unusual,,
Mechanic basically doesn't know what it is,, says it could be a valve stem worn( but if it was ,wouldn't it smoke all the time?)
I did a bit of research , blanked the EGR valve to test,, still smokes,,, no that so removed the blank.
COULD IT BE THE 5TH INJECTOR?? I can't even find the 5th injector to disconnect.
Any ideas, or any non dealer lexus mechanics near Yorkshire anybody could recommend. Im at my wits end. Its embarrassing to drive the thing in daylight
