Fixing all six first-track-day issues

theruleslawyer said:

1. Burning some oil in the braking zone. The engine is probably under a ton of vaccum and sucking some oil in. Reportedly it clears right up out of the turn, and doesn’t impact a high G turn alone. I need to check the oil catch can. Maybe its full?
2. Brake has inconsistent feel. I bled the brake on track. Some people say it is indicative of two things- A leaky master cylinder or air in the ABS. The ABS I need to see if I can get or borrow a tool that can do ABS bleed. I ordered a new master cylinder. Even if it isn’t the issue, it is a 25 year old part and probably worth freshening. Probably worth checking the booster vaccum lines too.
3. Check engine light. I ended my day since I couldn’t get scanned at the track. Torque pulled O2 low voltage and a bunch of throttle position errors. O2 maybe I melted a harness? I guess we will find out. The TPS errors I suspect are related to the autoblip. I’ll contact their support and see what they say. At least nothing major happened.
4. Some oil is leaking. I lost about 1-1.5L a day. Some of it burning, but I have a minor leak when hot. I’ll have to chase it down this weekend. Probably just the new oil cooler needs tightened.
5. Grinding noise LR- Either I’m starting to lose a wheel bearing or maybe the axle nut needs torqued. I know SKF trackers are in my future.
6. The tunnel is freaking hot– I think I’ll order a c6 tunnel plate and insulation kit and see if that keeps some heat out of the cabin.

1. The catch can was pretty full. I also found the hose pretty loose to the TB. I bet it was leaking.
2. Replaced the master cylinder and bled a ton on the brakes.
3. I took out the positaps and soldered in the wires instead. o2’s look okay.
4. I found the oil block to be leaking. It looks like the temp sensor and a plug. I added some thread sealant, cleaned the surfaces well and reassembled. I was tired and frustrated last time I put it together. Good news is the heat has formed the hoses to their new shape a bit and now it wants to stay in the correct location so getting the screws in is easy.
5. I had a spring in the parking brake loose. not 100% sure it fixed it yet, but I’d bet on the G forces causing the shoe to swing out and rub the inside of the rotor.
6. I added an insulation kit. It’s pretty!

I also managed to get 2 more bolts into the headers. I just drilled out the threads completely and used a through bolt. I also finally bought a cordless ratchet. OMG why did I wait so long? Instead of fighting bolts where you get a couple clicks of swing- ziiiiiiip and it’s out.
