After reading about all of the galled cam lobes that peolpe have been reporting, I decided to pull the valve cover and have a look to see if there might be any problem. I have not had any codes set, I was just curious. Well I found what I did not want to see.
The #3 cylinder high lift intake lobe is severely galled as can be seen below.
My car is an 2006 Elise Chassis #357 built in September of 2005 and has ~19K miles. I know some people are interested in this information to try and pinpoint the affected range of serial #s.
I took a look and did not see any issues with the holes drilled in the oiling tubes in the valve cover that others have reported.
The cam wear is so severe there are ~0.010” tall ridges at the edges of the lobe where there is not contact with the rocker. Thankfully, it appears there has not been a rocker arm failure (yet).
Looks like once the snow is gone, it will be time for a trip to the dealer in MA to have this resolved since the car is under warranty until November 09. Hopefully the warranty will be honored.
How have other people made out with this problem as far as repairing under warranty?
This really bites it, I was willing to buy the Elise mostly based on the perceived reliability of the Toyota engine and drive train. So much for that idea.
Can anyone tell me what the torque specs are for the valve cover bolts and the sparkplug coil bolts so I can button this back up?
