replace the timing chains?
 

Going through an early 911 low mileage motor to do a complete reseal. Split the case and all. Only 40,000 miles in 10 years. Obviously not driven enough. any reason to replace the timing chains while I am in here? They were new 10 years ago.

Thanks,

They are likely fine, but why risk it? If you are really budget constrained, then sure, go ahead and reuse them but if it were me, I'd' prefer to eliminate the risk and replace.

I know what you mean and bottom line is that the cost of new chains is almost invisible given all the other work being done. Just being practical, but why start now.

Thanks,

Using new chains on old sprockets is more likely to cause problems than re-using the old chains.
