The picture below shows the old paint markers that we had put on James' car at the 56k service. Even after 40k additional miles, you can still see them. This technique allows you to visually inspect your car to quickly verify that your critical fasteners are still torqued correctly. If you see that a paint line has shifted, this is a good indication that you need to retorque.
Once we inspected the car, we noticed that most of the fasteners had not moved. We still removed each fasterner, reapplied threadlock, then cleaned off the old markers and repainted the joints. These paint markers are readily available at auto parts or hobby stores.
One of the issues that we found during this inspection was the rear bushes had moved and the wishbones were making contact with the subframe. The picture below shows what we found.
Typically we see this on track cars but even high mileage street cars that are driven with some enthusiasm can exhibit this problem. Luckily we have a couple of solutions that can help: SL Bushes and the MONOballs or Nitron Bearings for the track/race focused cars. We have a previous blog entry about this issue: HERE
We are big believers in the fact that these Toyota powered Lotus can be reliable cars. The two basic requirements are that you:
- Keep the fluids & filters fresh
- Keep the critical fasteners torqued correctly
If you follow these basic rules you can run your Lotus for years with confidence and a grin on your face.
