Hey everyone glad to be part of this forum as I am new here but loyal Toyota owner! I’ve been in the market for a 2008-2012 Toyota Highlander, did my homework seems like a great SUV my step mother even works at Toyota dealership, and backs these years of Highlander. My only real question is how concerned should I be about the vvt cam noise upon cold start up? I’ve researched hours about this issue and it seems like it’s very common and some people say they’ve always have had the noise and had no problems then you get people that had to do whole engine tear downs to replace the cam gear. My understanding is the cam gear isnt being lubricated due to the fact the oil draining back into the oil pan over night and causes the cam pin to not move properly. Ive seen a tsb for the 2008- 2009 Highlander’s. I’ve even heard of people installing prelube oil pump to “solve” this issue. What are your thoughts should I be concerned about buying one of this vehicles?
