1. Attempting to use a g clamp to push in the piston on a rear brake caliper on my 1st EA with Douglas as an accomplice. Shortly before that we fkd up the rotor retaining screw and took us one hour to sort it out. N00bs FTL. A call to Bass Crazy revealed that the piston actually needs to be turned to go in. One fukked brake caliper later it was all good.
2. 1st motor replacement I attempted was in MRDOSE when it was white and wore FBF500 plates. Yep. Epic fail that one. Had it sitting for 6 weeks out the front with no motor. It came out OK. Tried to bolt it all back together the same way it came out. Torque converter attached to flexplate and everything. Fail. Pulled out gearbox, slid the torque converter in without locating it and then jammed the motor together with the trans. It made cracking noises but bolted together OK. Doug, Karl and Rob (baarge8) came round and helped finally get it fitted in the car. All OK.
1st day problems included a clutch fan that removed itself from the motor, fukked electrics and a gearbox that would fail to engage any gear on the first acceleration attempted, and then thump loudly on teh second attempt. The gearbox died on the second week =D
Moral of story - locate the torque converter in the trans correctly before bolting up.
To think we can do that sht in a day now

3. Having a loose starter motor bolt on TUFPAK with a leaking fuel rail after the motor change. The leaking fuel rail wasn't going to be a problem in my mind, what could spark? Eventually the loose bolt worked loose enough for the starter to not want to engage - instead making a slight spark where it was loose. Fuel ignited. 5 minute fire ensued. Celebration burnout occurred once the fire was out. Drove it home from Rowville with the loose starter bolt and fuel still leaking =D
There's probably more. A lot more.
