Hi Scotty , I have 2011/ Buick/ La Cross CSX , w/90,000miles , 3.6 L 6cyl , automatic transmission . The engine's timing chain is known to be a problem . When should I replace the timing chain ? Thank you !
I would change the timing chain when the engine is seriously misfiring. If your car runs fine, leave it alone.
Thank you VERY MUCH !!!!
