As an avid DIYer in the automotive world, I cannot stress enough how valuable this tool has been for maintaining and repairing engines... Thanks to my knowledge gained in practice, I can say that this tensioner is a game changer when it comes to camshaft locking. It is incredibly easy to use and ensures the timing of the engine remains absolutely spot on. However the only downside is its slightly high cost. Nevertheless, investing in such a tool with its high-quality build and precision is worth it in the long run..
