MINI Timing Chain G1 IWIS

Note: The kits by IWIS comes with the tensioner plug as well. The kit currently doesn't have the chain lube as shown in the photos.

MINI Timing Chain Kit for all Gen 1 MINI and MINI Cooper S. This kit includes both chain guides, a tensioner, and chain, as well as the front cover gasket, crank seal, and chain lube. At the shop, we've found that if you overheat your engine or run it without 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. This 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 quicker.

While this kit is not hard to install, you do need to know what you're doing, and we highly recommend a Bentley Manual to help guide you thru the process. You're 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.
