just like to add my own update..
Early batch 2005 Elise, not sure on assembly #.
Driving habits: Never tracked, but driven quite hard (I thoroughly enjoyed the car!) I would hammer it into 2nd cam as soon as the car allowed.
17,000 miles: during cam change, engine threw codes, car went into limp mode
damage: replaced cams, rockers, complete valve job, machined the damage from bits of metal going into the #3 cylinder. Every setting back to factory. Parts purchased from Lotus.
22,000 miles: Lost nearly all power, and an incredibly loud knocking noise, Also happened during cam change.
Damage: detonation of #3 cylinder, broken cam lobe #3, #2. you get the picture~
I live in san antonio TX, and the car has more than once had issues with keeping cool in high summer. More than once it went into limp mode due to coolant heat being above 210F (or whenever it starts flashing), usually in stop traffic. Both incidents happened during the coldest parts of winter.
For the engine build, we talked to lotus, $15,000 for a crated motor.
We looked at replacement used motors off celica GTS, and i believe two other toyotas, $6000-$7000 for low mileage.
Ultimately we just purchased every single individual part from Toyota, and are assembling it our selves. I believe it was $3000-$4000.
I believe this is the safest method to avoid the possible causes for this issue. If its a bad batch lotus received from toyota, or if its an issue with the cam cover, then I think I'll be fine.
Any thoughts or questions?
