AVENSIS: mark, i have toyota avensis t180 with white smoke

Customer Question

hi mark, i have toyota avensis t180 with white smoke issue, after lots of investigating have narrowed it down to being 5th injector problem, i have seen lots of these engines doing this and got told the ecu needed updating had this done by local toyota dealer, seemed to stop over fueling and white smoke stopped breifly... but now the only way to stop the smoke is by kidding it on with 1 5th injector in block and another with everything connected to it catching diesel in a container, now thinking did did ecu update alter anything or is there something else could be causing 5th injector to become wildly erratic at times but the just an evenly spaced clean injetion at others. hope theres a short resolve to this somewhat head scratching situation

Hello and welcome to JustAnswer!Although it's more common for an injector to cause a constant issue when there is a mechanical failure, it's definitely possible that the problem could be intermittent. If it's smoking white with a fuel small and excessive combustion noise then you very likely have a failed injector. You don't want to continue running the engine in this condition because it will damage the piston rings and cylinder wall.How did you determine the problem is with the number 5 cylinder?
