1997 BMW 540i Q&A
1997 BMW 540i Question: Plastic chain guide replacement -- $$$$?
The BMW dealer that services my 540i is telling me that plastic guide that protects an engine chain (timing chain?) is coming apart and if not replaced could damage the engine. They are estimating repair costs exceeding $10,000, which is probably not much less than the resale value of the car itself. Can this be right? - dhalbers
Replacing the timing chain ,guides ect is a huge job requiring special tools and about 22 or 24 hours labor to replace. Perhaps see if there is any BMW specialty shops in your area. Ask them if they have done this job before! - patrick mannion
Timing chain guides-rails wear off around 100-120 k miles and start making a diesel engine like noise. Three plastic guides/tensioner may result in breaking and the chain starts contacting the aluminum engine body. Timing chain and guides replacement job is an 18 hr job and the parts themselves cost around $1k. Your service is asking way too much. Do not even talk to them anymore. You can get a new engine even a new 540 for that price. - Visitor
Replacing a timing chain guide on an 1998 Ford Explorer is running $2,000 US. This is an outragous repair and should have been recalled and repaired for free by Ford. Timing chain guides should not be falling apart in 100,000 miles. This repair is as costly as a total new engine at 100,000 miles. - Visitor
