    Rated 5 out of 5 by Great product The HLA's on my 1990 Eunos (MX5) were very noise even after an oil change. Not surprising after 135,000K. After a single treatment with this Wynn's product they are now virtually silent. Well worth the money. 06 September 2016
    Rated 5 out of 5 by It takes time people!! I have a Porsche Boxster S which was suffering from a noisy tappet on tickover. I put this stuff in 2 - 3 weeks ago and the noise is pretty much gone altogether. Please bear in mind this is not a miracle cure that will work instantly. It takes a lot of miles for this to try to break down the deposits 20 July 2016
    Rated 1 out of 5 by Useless No change in my hydronic lifters noise before treatment and exactly the same after used 22 May 2016
    Rated 4 out of 5 by Definite improvement. But not a miracle cure Used this on my 03' Golf Match 1.4 Went for a 50 mile motorway drive and there is a improvement but still ticking. Not very expensive so would recommend you give it try and see what happens. Engine runs smoother and more quietly. But no miracle cure. 26 October 2015
    Rated 5 out of 5 by cheap solution to misfire caused by dticking valve my engine warning light kept coming on and car was lumpy at idle speed so I plugged my OBD 11 scanner in and fault code was for misfire cylinder 1 but only at tick over I had used EGR valve cleaner which helped a little but fault continued so I ordered a compression tester thinking valves or maybe a piston ring were to blame then I saw a video on youtube about sticking valves being gummed up so looked for a cleaning product and found this stuff , I followed the instructions and yippee car ticking over like a swiss watch , great value. 10/10 (compression tester will be a nice addition to my tools) 14 September 2015
    Rated 1 out of 5 by Wynn's Hydraulic Valve Lifter 350ml Total waste of money do not buy this product........ 30 June 2015
    Rated 5 out of 5 by Nice and quiet now. Have been plagued with a noisy hydraulic valve in my 90k mile V6 Freelander for sometime. Saw the positive reviews on here of a possible inexpensive cure and decided to give it a go. Success. On start up in the mornings, especially if it had been left a few days, it was very noisy. Much quieter now, sounds like a sewing machine. Would definitely recommend this product. 16 May 2015
    Rated 3 out of 5 by had very little effect. My vehicle is average mileage for a three year old vehicle. The very long service interval set by the manufacturer means that the oil is expected to be in the engine for 20000 plus miles. The hydraulic lifters were making an awful noise especially when cold. The treatment had very little effect indeed. I ended up having to change the oil and filter twice. First time with some low cost oil which i added an engine cleaner to (not the wynnes engine flush but a product called "tec4 oil system cleaner" which i kept in for a short journey across town). Then a complete drain to get every last drop off oil/cleaner out before pouring correct oil in and replacing the filter again. 08 March 2015
