Timing change replacement
My 1991 D21 Nissan pickup has 250,000 km and has a rattle from the timing chain when starting cold. I've been told that the solution is to change the timing change. The rough estimate for replacement here in BC is $1500. I've never had to do any work on the engine or the drive train apart from the clutch. Syncro rings in the transmission certainly aren't as smooth as they used to be, it doesn't burn any oil, runs great, body is good shape. I'm retiring and would like to use this vehicle for another 15 years or so. Am I just throwing good money away to do this repair or should I just drive it till it drops? Thanks. Jim
