White Smoke During Acceleration.

[Lofty901]

Hello chaps, had my is220d since November. Has a week and had vsc light problem. Egr valve cleaned, inlet manifold removed cleaned, egr eventually replaced and finally in January got a new cat fitted after several clean outs failed. No lights after 3k miles but their is now a lot of white smoke coming from the exhaust. It's not overheating and no difference to performance. My Mpg varies from 34 and 49mpg depending on town or motorway driving. It is a 56 plate 93k miles and 7 of the 9 service stamps are from Lexus.

Thanks in advance for any help.

i been having that, also coolant sprayed over the engine .... Head gasket gone.... going into Lexus MK tomorrow for new engine

70k on mine with full service stamps.... all work being done and paid for by Lexus :)

Why does the head gasket going result in a new engine? Can't the head gasket just get replaced?

It is very often the top end or short engine replacement. The head itself can get twisted/warped quite readily.

However there are other issues of carbon/sooting up of the engine to quite bad degrees. When this is seen it will invariably mean the whole engine needs doing. EGR often replaced too.
