well i changed the injector washer....15 minutes to remove the injector and the rest of the day removing the old washer welded into the hole with the black gunk blowing by. what a pig of a job it was....if i was still in the trade and doing a customers car it would of cost at least 200 quid maybe more to do the job. good news is the injector is no longer blowing...even better news...my son who owns it has bought a honda civic type r instead.... really bad news... hes gifted the lexus to his brother for his birthday and i still have the dubious pleasure of mending it when it breaks again.

i have an identical issue,no2 injector blowing by...i have just ordered a new washer and will be trying a fix soon. its been blowing for some time i think,could not hear it till i pulled the top cover off while servicing the sons car,as its been like this for a while and running fine i guess a drive to your repair man will not be a problem.
