I had a guy keep trying to race me in his BMW M4. He kept egging, so finally, I said screw it and handed him his ass. Well he wasn't satisfied, so he wanted to go again. Again, I handed him his ass. But this time on letting off of the throttle, I had some serious popping and from places that shouldn't have popping sounds coming from.
So, since it's my nature, I thought of the worst things that might have happened and pulled over. It was running fine and the popping was gone. No weird sounds any more. Took it easy for the 15 miles left to go home and parked it in the garage. Like I said before, I immediately think of the worst and figured lets do a compression test and see if it's down on any cylinders. I park in the single bay side and I parked too close to the cabinets to work on the R/H side.
The next AM, which is today, I started it to move it to get clearance to work and when I started it, I had sounds of an exhaust leak. I was thinking oh screw me what else did I F(!K up! Got the car on jacks and hanging on the left side was the downstream l/h side O2 sensor. The J shaped defouler broke at the the area above the hex closest to the exhaust bung. So, that relieved me a bit. Did a compression test and all were within 15lbs 260-275 according to my Mityvac compression tester. I did the test on a cold engine so that any damage should show itself right away (that's what I was told to do). This was a good time to change the plugs, just have to wait on the defouler to come in along with a new O2 sensor. At least I didn't screw anything up that would cost big dollars.
Note: After doing a some research, what I thought to be a Vibrant product, was not. It was a "Vibrant J Style" defouler. What did I learn from this? Read the description carefully of what the onlne seller is listing it as and if it states "style", it's a knockoff. Oh well, it cost me the price of a O2 sensor.
