Timing Belt Or Chain
I have been looking around and I want to ask ask a question. I wonder:
Does the 4.6L engine in the 460 have a timing chain or does Lexus still use a timing belt?
The further upstream a car gets, I guess there is a greater possibility that it will have a chain instead of a belt. I do know that Toyota's philosophy has been to use the belt instead of the chain because of noise issues....a belt is much quieter than a chain, especially as time goes by. The chain stretch is a reality even with a hydraulic tensioner using engine oil.
If it does have a belt, I wonder how difficult it is to change? I suppose a car like this is SUPPOSED to go to the dealership for maintenance / servicing, so for most folks that would not be an issue.
I am just wondering.
