RAV4 with white smoke

Post by victor2k »

Hello,
The car has arrived without injectors,with bad battery so the initial fault code check was skipped.The engine is 2ADFHV /2011 without start issues but with a lot of white smoke.
At the beggining I checked the compression,is ok(measured 22bar without sensor +adapter compensation for 2.5 ml,file attached).
I replaced the 5th injector(maybe the original have some leaks),no improvement.
I suspected a late injection so I measured the cylinder pressure with the injector plugged,no late injection,the burning event is at 8.5* ATDC(as I know the maximum pressure in cylinder must be obtained at 10* ATDC).
Tomorrow I will reprog ECU for sporadic white smoke,in my case the white smoke is present with the 5th injector unplugged...
Any advice is wellcome.
Thank you
