![]() To prevent any more coolant caps from blowing out, I changed them for a looped line. Now to recap the track day I did a couple weeks ago. I didn't think I could cut off more than 2. I rushed out there, forgetting to start the data logger or roll down my windows, and surprisingly cut 4 seconds off my previous run. He got there just before the end of run 3 so I actually didn't miss a run. I called a nearby parts shop to reserve a cap and called my dad to bring it to me with some coolant from home. I popped the hood and saw that one of the caps over the ports that would've gone to the heater had burst open and was sprinkling coolant onto the gearbox. At the end of my second run I got a decent time but heard that all of the course workers were smelling coolant from my car, and now I could smell it too. On the first run I went out and one of the sway bar link tabs slipped again, so I had to abandon the run and fix that. I figured the car was pretty well sorted out by now. The morning of the event, my offroad rally navigator wanted to share since he was between cars, and he'd shared his rally car with me once before, so it's only fair. I still think my usual alignment shop was trying to give me a right-turn-biased setup to be faster around the bigger track here, even though that's not a course I'll ever compete on. The guy did a good job, and this is a shop with a laser alignment machine I can get the car to on my own without taking a day off work. Took the car on the day before to get the alignment checked, at a different shop this time. My car is the 2nd least powerful of any of the potential contenders for 3rd (after my navigator's rally car), one of which is the electric sevenesque - I dread the day when the driver figures out that if he were to artificially limit the car's power output for autocross to 1/4~1/3 of full power, it would give his right foot a sporting chance at controlling wheelspin (and the related gratuitous spinouts) and make the car nearly as dominant in autocross as it is in drag racing.įinally have some time to recap the autocross on the weekend before last. I've beaten Toyobarus before, but with drivers of questionable skill, this guy I used to see at track days when I was a teenager so I know he has experience. One guy who just bought a Toyobaru and took the 2WD class win at the last event is just 2 points behind. I'm one of 4 competitors tied for 4th in 2wd class, behind my navigator who's just 2 points ahead. I might be able to bring home a trophy for the first time in quite a few years at the end of this season. After the autocross I'll get the wiring checked just in case there's a bad connection somewhere, if not I'll get a replacement smuggled in around March next year. So it's disabled for now, luckily I got plenty of tuning in before this happened. It isn't outputting calibration values on startup as it should and outputs noisy nonsense readings of 9.7:1 (below the normal minimum output value)~15:1 while driving. There were no physical signs of damage to the WB02 controller, but electronically it looks very FUBARed. Might've been a spill from an oil change the day before.Īnyway I got permission to leave the car at the track for a couple days, I'll take it to the shop that did the crank sensor bracket mods this evening. Oil has spewed from the dipstick tube before, but I had the dipstick velcro-strapped down and didn't see any oil around the top of the tube. I don't know where the oil on the timing wheels came from. One suggestion I got is that the stock timing indicator bracket might've been bent close enough to the timing belt to slice it apart when it bows out at high RPMs, apparently it doesn't take much. You'll also notice the fresh streaks on the alternator belt, indicating that the sensor bracket is still making contact with that belt at the very highest RPMs, so it needs some more clearancing. The crank sensor bracket might be an immediate suspect but it's not that close to the timing belt. Half the timing belt had been chewed off by something. I had a look around and soon saw the problem: ![]() ![]() When I popped the hood I saw some smoke coming from the pulley side of the engine. As I drove back in I could hardly guess what it might be, it seemed to have something to do with engine RPMs, but maybe a rear sway bar tab came loose again. My wrecked-engine PTSD sprung into action and told me to get back to the pits ASAP. ![]() This setting works well, it's almost impossible to get burst knock now:īut on the warmup lap (warmup for brakes and tires anyway, the engine was already warmed up and I was running it hard from the start) I started to hear a faint scraping/whistling noise. Only work I'd done since the crank sensor bracket mod was some tuning, mostly on the accel enrich settings. ![]()
