Description Reviews MINI Timing Chain Kit for all Gen 1 MINI and MINI Cooper S. This kit includes both OEM chain guides, a tensioner, and chain. We have found, here at the shop, that if you over heat your engine or run it with out oil for too long, you can wear out or break the chain guides as well as stretch the chain, or cause the tensioner to stick and fail . Also if your engine clatters on first start up then goes away, then this kit is for you. As an added benefit, we are now cryogenically treating all chains and tensioners in all of our timing chain kits. The cryogenic “heat treating” process is where the material is cooled to approximately −185°C (−301°F) with the use of liquid nitrogen. This increases the amount of martensite in the steel's crystal structure, increasing its strength and hardness. Which in turn will not allow the chain to stretch or the tensioner to fail as quickly if ever. This keeps your motor in time better as well as quitter. While this kit is not hard to install, you do need to know what your doing and we highly recommend a Bentley Manual to help guide you thru the process. Your also going to need some special tools to make the job happen correctly and we rent out tools to make the job a bit easier and cost less. You will need the cam tool, belt tensioner tool, and the crank pulley tool. You should also replace the crank bolt and maybe the cam bolt. 1 Review 5 Mini R53 timing chain Posted by Pablo Hernandez on 13th May 2018 First just wanted to thank Chad for helping me find out about my timing issue....(stretche) Timing kit was shipped fast definitely be difference on my R53 No more rattle...
