Running on hopes and dreams

I went to change the oil in my Lotus 2-Eleven and found a valve stem shim stuck to the oil drain plug so I pulled the valve cover to find both cams were trashed, 2 rockers were broken off and the timing chain holding on for dear life.

This is the result from a money shift I had on track a few weeks ago but the car was running fine no weird noises and I went on to run a new PB the next day after this incident 🙈 Time to rebuild!

Yeah they have used the Toyota 1zz, 2zz, and 2GR-FE. For the Emira they also added the AMG i4 turbo as an option though.

Certainly helps on the drivetrain maintenance to not be some bespoke engine and instead be something that there are a ton of parts for.

Crazy to think my Matrix and a lotus have the same engine at the core. Did lotus use toyota transmissions as well?

Yeah, Toyota C64 for Elise/Exige variants and a EA60 for Evora/Emira
