Review on Rislone 4416-6PK Smoke Repair: 16 Oz, 6 Pack - Seal Rings Quickly & Effectively! by William Lin
It worked for me! Passed California smog.
Purchased this product as a last gasp hope of passing smog at referee center in California as vehicle was failing smog visual and smoking. It worked. Was able to pass smog and good for 2 years. Just added another 2 bottles to my 06 BMW 750li after recent oil change and seems to jave stopped the smoking again.
Pros
- Thumb up. Strongly recommend to all buyers.
Cons
- This is useless. My car kept smoking anyway.
