Replaced my starter last night. The one I installed about 4 months ago was arcing across the solenoid. Luckily, it was still under warranty so it only cost me time and not money...
Decided it was time to re-torque the heads I installed about 2 months ago. Turns out I torqued too much and broke one of the bolts...
Luckily, I'm versed in replacing the heads so this shouldn't take too long to fix. The store will have them in on Monday.
