Land Cruiser 80 - 1HDFT has a strange knock / ticking sound on startup & idle

The infamous 1HDFT knock / tick has appeared in one rig. We have retraced the sound to the air intake and naturally it seems to be coming from the block. However, it is a common issue with Toyota HD engines. Some other facts are: - Oil level is fine and no reduction - Mobil oil was changed recently 450kms ago - Mobil oil was shifted from Mineral based to Semi Synthetic same viscosity 15W-40 - Liqui Moly Ceratec was used 5000kms ago with previous oil ( 2 cans to 10 litres of mobil oil) - Oil filter is changed on every oil change - Turbo was inspected and is fine - No oil in air intake apart from minor droplets - Acceleration and boost is fine, normally operated The proposed solution has been highlighted in the video and we hope it works out if you run into similar problems. Naturally other issues can be evident after a qualified mechanic inspects your vehicle but it a good to check if you recently changed oils within last 1000kms. Stay Tuned!
