Hi just done my timming chain 2007 d40 @ 108k km because a friend of mine done an engine @ 180k and cost him over $8000. The only
reason i noticed it is because he jst got a new motor in his and it was a lot quiter than mine. I fitted the yd25 dual row conversion .with the old one this is what i found bottom chain streched by 10mm and tensioner guide rooted .Would not have been long before the chain snapped or tensioner guide failed. After doing this the truck doen not blow smoke anymore and spools lot quicker with more power.I was thinking it was just the motor getting little noisy with wear but as you can see its poor nissan enigineering.timming chains should last at least 500k ,hell iv seen a Exel Huindai snap a belt after 350k.If you own a yd25 get it checked oyherwise could cost you $$$$
