No piston slap, or valve noise, no problems with the timing chain tensioner. Always run Pennzoil Conventional 5w30 since new.
It has the 1ZZ-FE that is very similar in design to the 1NZ-FE in your Yaris. Have you tried it yet ?
I'm gonna ask my dad about the symptoms you mentioned for both your Rav, and your Yaris. He is a Toyota MDT at IRA. He's been working on Toyota's for 30 years. I can let you know if he's seen a trend. Also if you had the Rav serviced at IRA, I may be able to have dad pull the RO to get the tech's comments if you like.
Unfortunately he only has access to RO's at IRA Manchester. If it was another dealership, then I can't get the tech's comments.
Also how many miles are on your Yaris ?
The Yaris has 26K right now. The Rav was serviced at IRA Manchester, IRA Tewksbury and Mainly at Hurlbert Epping. 05 RAV 4 VIN is JTEHD20V056046507. Yaris has not been in for anything other than a tire change. Just wondering if any one got the engine repaired or they're just dealing with the racket and oil consumption. Thanks.
