Update on startup rattle
Hey guys, I just wanted to make an update on the post I made last fall about an issue I had. Maybe it could help somebody troubleshoot this kind of problem.
The symptoms were:
-Short but severe rattle when the car was sitting for more than an hour
-P0024 dtc for « advanced timing exhaust b2 (driver’s side)
-Also had a weird intermittent issue with the idle that would climb up to 1.5k rpm randomly and stay there when sitting in trafic but return to normal if I turned off the car and back on.
I ended up replacing both VVT gears in the end and now the dtc hasn’t come back in about 500km and most importantly no rattle.
Made this post because I couldn’t find information about VVT gears going bad on the vq, just found videos on Toyotas and Hondas.
So if you know your tensioners are good the rattle may be caused by the gears having gone bad.
I bought both gears #VTG0024 on amazon but they are genuine Hitachi ones for about 400$CAD each shipped to QC.
