how to know if my 2001 rav4 has a variable cam gear
Need to buy a timinig chain repacement kit. Don't want to start untill I have all the parts
on hand but I don't know if the engine has a variable cam or not unless I open it up or is
there an easier way, like a lable under the hood?
On the top of the engine will have VVT or VVT-i. (Those are V V not W's) VVT Variable Valve timing, VVT-I is Variable Valve Timing-intelligent

It uses oil pressure on the cam to move lobes to increase lift and duration https://www.youtube.com/watch?v=T0G5KLN4a_w
