Oil coming out the dipstick and the ccv lines. The engine was knocking also. After 3 bottles of this stuff it's back to running normal. ### ⭐⭐⭐⭐ It works *by K***A on 18 March 2026* It works ### ⭐ One bottle was open and leaked all over the box, the bottles and my porch. *by B***E on 11 July 2022* Our order came and one bottle was open and leaked all over everything including my porch. I honestly thought no big deal, I can take pictures and have them send us a replacement bottle...ha... no such luck. Since we ordered the 12 pack we were told that we can not get a replacement for the bottle that leaked. I would have to return all 12 bottles! That seems ridiculous, so I am out one bottle and that just irritates me so much. I will remember this when it comes time to order again. I will not be ordering this from here ever again. So frustrating. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/275878445-bars-leaks-rislone-4447-12pk-compression-repair-with-ring-seal](https://www.desertcart.pt/products/275878445-bars-leaks-rislone-4447-12pk-compression-repair-with-ring-seal) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-22*
