Engine Noise
What kind of failure causes a rattling noise in the engine? It's loudest at about 2.5k and tracks with the speed of it. A pretty engine savvy friend of mine suggested it may be a rod bearing. Any one agree?

I disconnected the battery for about a minute then hooked it back up. No more SES light! I'm going to begin tearing apart the motor tomorrow, bottom first. There is definitely some kind of mechanical failure in there. I hope it's a rod bearing. $100 for a set of those vice $2-3k for a replacement motor.

Pretty sure I rolled/wiped a bearing. Pulled off the oil pan in preparation to pull off the bottom half of the motor and found some copper shavings in the bottom! It's good news and bad news. Bad being that something crapped itself. Good being that it is just a bearing, not expensive.

Yeah. Ordering parts tomorrow. I normally use 5 or 10w30 all synthetic with a good filter like K&N or Purolater Pur One. I think maybe my pressure dropped too low during a high RPM extended turn.

Is it a rev up with oil consumption?
Edit: Saw your post. Sorry about your car. Give us a call if you need anything.

What funny about this thread is that I'm have the exact same problem with my z, the noise started at about 2.5 to 3k rpm and continued as I drove. I was told by a friend of mine who's a tech at nissan that my rod is knocking. Also found little metal shavings in the oil.

UPDATE: Finally got around to removing the old bearings. The rod bearings on #5 cylinder were F'd. Some of the others were showing some of the copper backing. I'm glad I went ahead and ordered rod and main bearings! I'll post some pics of them soon.

Hi there, I've got a 1.0 litre Yaris Blue edition, 04. I've had it for just under two years and it hasn't gave me any problems so far. I noticed today that when i was changing from 1st to 2nd gear, the engine was giving a kind of whirling noise. After i realized, i turned off the radio to see if it was happening all the time. It only seems to happen if I'm doing between 10 and 15 mph and doesn't happen every time, although quite often. It's definitely not the way I'm changing gear before anyone asks, every other gear change is fine apart from 1st to 2nd. I've noticed on the forum a lot of other people seem to have problems with the yaris gear box. Any clues? huh.gif
