I was wondering if it is normal for the ignition coil to sit slightly tilted when the bolt on the ignition coil is tightened down. I noticed this recently after running into a small patch of water during some heavy rain last week which lead to the car sputtering. After a short investigation I found the problem. I pulled the ignition coils off and found a slight amount of water. Like a couple drops which after drying out seemed to take care of the sputter and misfire. Also the boot instead of coming out in one piece came apart in several pieces when I was pulling them out to check so I'll be getting new ignition coils very soon. The rubber stayed in the engine along with the spring, the fuse popped out along with the top of the ignition coil which I had in my hand. Three of them did this, one came out as one piece. I noticed water in two. Rolling up a paper towel and pushing it down around the spark plug got the excess water that was around it, and I left everything open for some hours to dry out in this texas heat. Running fine at the moment. But to my main question, I thought it was odd that the ignition coils do not sit straight when tightened but instead at the slightest angel. If I turn the bolt back a little it sits fully horizontal. There's a slight lip where the bolt tightens the coil on the engine, and the bolt tightens down into it.
