Possible fault on Yaris 1NR-FE engine - Toyota Yaris Forums

Geoff Peace · 05-16-2013, 03:20 PM

I have heard of two cases recently. one at 2,000 miles the other at 4,500 miles from new, of piston slap combined with what has been described as 'carbon build up' on the cylinder head on this engine. This causes a rattle at startup similar to little end chatter it disappears when the engine is warm as piston slap usually does, unless it is excessive. Toyota want to fit new pistons! To me this is beyond belief. Carbon build up at 4,500 miles, and piston slap on 2012 cars. I thought it was a wind up, but evidendly not. Has anyone encountered any such problems in the USA? I would be most grateful for any information.
Regards Geoff Peace.
