The first time I used it I was really sceptical about this product still leaking for two days but as I drive along the leak suddenly disappeared. So when I did my oil change I pour another bottle no more leak up to now. I think it does its job kudos to the seller and kudos to bluedevil. ### ⭐⭐⭐⭐⭐ Good product *by on Reviewed in Canada June 28, 2025* worked as described ### ⭐⭐⭐⭐⭐ Klein lek *by on Reviewed in the Netherlands May 29, 2026* Gekocht maar nog niet gebruikt, wacht nog op olie wissel. Recomended in vers olie. Gekocht voor kleine lek/zweet van de achterste krukaskeering op mondeo mk4 .Snelle levering. ## Frequently Bought Together - BlueDevil Products 00234 Rear Main Sealer - 8 Ounce - BlueDevil Products 49499 Oil Stop Leak - 8 Ounce - BlueDevil Products 00243 Stop Smoke & Engine Repair - 16 Ounce --- ## 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.gr/products/733094769-bluedevil-products-00234-rear-main-sealer-8-oz](https://www.desertcart.gr/products/733094769-bluedevil-products-00234-rear-main-sealer-8-oz) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-06-29*
