## Overview

Liqui Moly 20004 Hydraulic Lifter Additive is a premium lubricant designed to improve engine oil performance by enhancing lubrication and cleaning valve bores. Suitable for turbocharged and catalytic converter-equipped vehicles, it prevents hydraulic lifter noise and reduces engine wear. Each pack contains two 0.5L bottles, making it an essential upgrade for smoother, quieter, and longer-lasting engines.

## Description

Liqui Moly's Hydraulic Lifter Additive damps the noise produced by worn hydraulic lifters. Cleans valves and holes in the lifter and promotes optimum operation. Add to engine oil, for all gasoline and diesel engines with and without turbo-charging. Tested for compatibility with catalytic converters. Liquid Moly's Hydraulic Lifter Additive can be mixed with all commercially available engine oils. 300 ml is sufficient for up to 6 liters (6.34 quarts) of engine oil.

Review: For my specific problem, it has worked perfectly for a full year. - An older boat, with twin Chrysler Marine 360's, with intermittent hydraulic lifter noise at idle on starboard motor. Isolating the noise to the specific location suggests one or two lifter(s) are (occasionally) remaining to some extent collapsed, resulting in increased clearance and thus noise. At higher RPM this disappears, probably as a result of increased oil pressure. Pressure gauges are in PSI and indicate that Oil pressure in the motors is within all specs at idle and speed with a solid margin of safety. Maintenance records indicated a sticky lifter(s) in past, but are incomplete in regards to service performed. Vessel is used and on third or fourth owner with rebuilt blocks. Both have sound compression and run smoothly with about 500 - 600 hours on the rebuild. How much was done and by who is unknown. 360 engines are flat tappet cams and are run on high ZDDP Oil specifically for this type of motor. To see if the lifter(s) could be freed up or performance improved, I added the Liquid Moly Hydraulic lifter additive to a fresh oil change. After an extended run of several hours, no lifter noise has was heard. The oil appeared to change color to a darker dirty color more quickly over the next few weeks of testing. I speculate that this is the result of the additive performing the described cleaning action. As a result of the discoloration, an earlier than normal oil change (1 month) was performed based on appearance (not analysis) and the additive used again. The theory was if we dissolve the crud; then remove the crud and start clean. Seems to make sense? A third change has just been performed after a full year/season, and still no noise. I continue to add 1 can per engine at each full oil/filter change. There was no desire to deal with the expense of new lifters/cam issues on an older rebuilt flat tappet motor. The engines are maintained carefully, and one can will be added to the appropriate range ZDDP oil at each change. My experience indicates: If the motor is mechanically sound, and lifter binding or clogging is the apparent cause of issues. Then this additive appears, as with many of the reviews, to restore the lifters to improved performance and quieter operation. As a comment. No engine additive can improve a problem if the internal engine condition is not suitable. In other words it can only improve the problem it is designed to fix. For this additive: low oil pressure, excessively damaged or fouled lifters, too much or too large dirt to overcome, metal particles in the oil, etc. could limit or prevent successful noise reduction. That's not a product issue, it is that these products perform a specific action and cannot work miracles on a junk motor. Negative reviews don't always take this fact into account. It can't rebuild a seriously damaged motor. It appears to clean a basically sound older dirty/worn one and provide improved lubrication and performance. It is not "Snake Oil". in my experience and did the job we asked of it extremely well. I first verified the basic criteria of engine vacuum, oil pressure, and smooth idle, etc. Then it was not hard to propose the cost of a new cam/lifter set vs a try at cleaning them up. I would never change lifters alone on a flat tappet marine motor, so we would have had to change the camshaft and lifters in place, then break in. I do not claim to be an engine expert, but for this specific situation, the thought was what have we got to lose? So far after a full season of run, it has been a great success. I will continue to use it at each oil change.
Review: Helped reduce noise but not an instant fix - I tried this Liqui Moly lifter additive on a car that had some ticking noise and it did make a difference, but not immediately. After driving for a bit, the noise became less noticeable and the engine felt smoother. From what I understand, it works by cleaning internal oil passages and improving lubrication, so it may take some time to fully show results rather than fixing the issue right away . It is important to mention that this is not a miracle fix. If the lifter problem is mechanical, this will not completely solve it, but it can help reduce noise in mild cases. The bottle came sealed with no leaks and everything looked fresh when I opened it. Overall it is worth trying if you have minor lifter noise, just keep realistic expectations
