    I did remove a relay box (2 10mm screws and swung it to the right). I have pretty small hands so was able to get around and into everything else. The torque wrench was a pain to get into position. I used a 2 inch extender and swivel extender. If there was a 2 1/2 extender I think that would have worked best.

    2007 Prius w 129k, plugs were changed at 86k. Chk engine light came on and code was #3 cylinder misfiring. Pulled #3 cyl coil & plug; plug was crusted, as were the other 3. Rock Auto - 4 - Denso SK16R11 Iridiums for $25. ; changed all plugs. Generic coil was $30. (As opposed to OEM Denso for $85 @ AutozoneCoil). After 8 miles code cleared. No problem w previous use of anti-seize goop so I used it again. I am burning some oil so my feeling is that that is what is crudding up the plugs. Just have to change the plugs closer to 40k than 100k. Anybody else having problems with oil usage ? Regards,

    some folks do have oil usage problems; there are several threads about it. pennsoil platinum oil is rumored to remove deposits in your engine. if the rings are sticking, it might help.

    I've used pennzoil platinum on my oil burning 2010 for 30000 miles and it has greatly slowed the oil burning. Went from 1 qt every 1.5k miles to now 1qt every 3.5k miles
