Liqui Moly Hydro Valve Additive, 300 ml

Vortec 6L V8 lifters started to make some noise especially during cold mornings and it was getting louder and louder fast. Tried to flush the engine twice but no help although engine got bit smoother. Throwed this in between the oil change and the noise completely disappeared fairly quickly. Now even that the truck is sitting 3 weeks in a weather between 0 to -15 in C (32 to 5 in F) there’s absolutely no noise in cold start while the engine is warming up. I’d still recommend the engine flush or several of them as the noise is usually about the poor oil flow (dirt all over the place) and dirty & sticky lifter rods. If this does not help, manually clean the rods and inspect the rockers. Bit time consuming but fairly simple job, tons of YouTube videos available for sure. Act fast as more noise more damage eventually. Also understand what you’ll be doing. My V8 is a 2003 engine that is a) in a good shape (piston pressures solid 13 bar) and b) the engine does not have anything fancy in it – just simple V8 (no variable this and that, no eco throttle pistons to save fuel etc.). As the magic of these is the change the oil structure from viscosity point of view you can actually do more harm than good with your engine especially with the newer ones.

I don't know what's in this but it worked straight away with the noise from my tappets. The garage wanted £500 to repair it. Easy to use just pour it in the same place as your oil.

Excellent Product. Quick Delivery Easy to pour into engine Added to Engine immediate result. Reduced noise to zero. Highly recommended.

Ok

Thank you very much!

It does what's writin on it

This product is liqui moly hydraulic valve lifter additive. Not Hydro Lift . Just buy hydraulic lift additive at £8.50 and not this at £14.00.

Usato dopo il cambio olio, sono spariti i rumori della valvola motore che batteva! Fantastico

Ein wirklich tolles Produkt, das sogar funktioniert. Man darf keine Wunder erwarten aber die Geräusche werden definitiv weniger

Mycket bra, funkar på min gamla mitsubishi

Çok uzun süre araştırdım araçta lifter ve itici sesi her ne derseniz deyin daha yeni başladıysa ve ses az seviyelerdeyse kesinlikle ise yarıyor ama tamir edilmesi gerçeğini değiştirmiyor büyü beklemeyin sesi azaltıyor ama tamamen kesmiyor Hyundai Elantra 1.6 dcvvt aracimda 10 bakım 100 bin km yakın kullandım eğer yağ oranıyla güzel ayarlarsanız keçe falan patlatmadan yağ kaçağı olmadan motor içi ayna gibi olur ve uzun süre sorunsuz kullanirsiniz

Excelente producto y de calidad los recomiendo
