MINI Cooper R56 Turbocharged Engine Timing Chain Guides Replacement (2007-2011) | Pelican Parts DIY Maintenance Article

[Q] Install the timing chain pretensioner tool and tighten it to 0.6NM (green arrow). Then install the camshaft sprockets and tighten the fasteners (red arrows). These fasteners are single use; check with a MINI repair manual for the most current torque spec. MINI now recommends removing the pretensioner tool and installing the timing chain tensioner. Once you do that, rotate the engine one full rotation and recheck camshaft timing. Install the crankshaft and camshaft locking tools and be sure everything is aligned correctly. If your timing is correct, reassemble the engine. Take your time installing all removed items and reseal everything with new gaskets. Be sure the wiring is routed as before to avoid issues. Once assembled, replace the engine oil and top up the coolant. Run the engine and recheck your work. [UQ]
