In most cases, a timing belt kit will consist of the belt itself, 2-3 idler pulleys, and a tensioner. When the job is done, all these components will be changed out. In most cases, a timing belt kit will run between $100 -350. Labor on most timing belts is between 3-5 hours, putting your total cost between $400 -1,000.
The timing chain tensioner is expected to last between 80,000 and 120,000 miles. However, there is no recommended time frame to change the tensioner. The device is expected to run long and should be checked regularly.
October 13, 2022 by Carolina. A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves. The valves themselves will bend and potentially ruin the

To prove that point BMW has always performed several long distance tests on its new engines before they are put on the market.From what I can tell, (probably like lexus) a well taken care of bmw will last a very long time. As long as a car is not a lemon, the life of a BMW is most likely determined by how well you take care of it. If you treat it well, expect 250000 miles. 7 posts · Joined 2019. #1 · Sep 15, 2019. I recently purchased a 2005 GTO with 191k miles. Do I need to change the timing chain at 200k or is it designed to last longer. The owner changed the water pump but didn't change the timing chain while they were in there. I tried looking at forums and they said it went for the life of the motor or Mikola200 said: as E46's generation gets older we might see a few failures. I believe it is supposed to be checked and tightened once in a blue moon, smth like 150k miles or so. BMW uses spring loaded and/or hydraulic tensioners in just about everything with a timing chain. There is no adjustment possible.
A timing chain can last for more than 200,000 miles with proper care. You may never even need a timing chain replacement, but you should book a check when your car reaches 125,000 miles . Be sure to invest in regular oil changes to keep it well-lubricated.
Based on RealOEM, there was a part number change for the N20 Timing Chain starting 01/2015 so we can assume then that N20 and N26 engines with build dates of 2015 have the updated timing chain and components. Up to 01/2015 – 11317584084. After 01/2015 – 11318648732. As of this writing, the update parts are back ordered and will soon be
