Yaris - 2010 - 2NZ

[lasherza]

Hi Guys,

At the end of my tether!. We have a Yaris only around 120k kilometers on the clock. South Africa so in Km's .

We had a head gasket blow around 5 years ago, apparently water pump broke and like no warning head gasket was gone. So head was skimmed and engine sorted out. Sorry not very technical.... but the car did come back " working"..

What was noticeable for around 2 years or so, was a foul odor like rotten egg smell in the cabin every now and again AND fuel economy was WAY DOWN!

Took it back to the mechanic countless times ..Could not find the issue. Finally on close inspection we saw that on connecting the engine back he FORGOT to connect the Oxygen Sensor at the back!!!!

Anyways smell was sorted but fuel economy has remained crap!. Also there is no very noticeable blue/greyish smoke in the mornings!. Oil consumption not bad i suppose ..but fuel consumption is bad.

Cleaned the PCV valve recently...no help...but it was really fouled up. Not sure which way to go now! . The car is still relatively new . to note though long distance journeys a bit better. Attached a still pic of the smoking as could not upload a clip.

thank to everyone who replies!!!
