Helping a friend, with timing setup with variable valve timing.
She has a 2003 trailblazer 4.2 engine and has it out of the vehicle, all new parts and head is rebuilt.
Question is how exactly to set the vvt, at full advance?
Alldata states when installing the cam sprockets and chain to set the exhaust side to full advance. I am not finding much information on exactly how to do this. Does she need to rotate the camshaft clock wise or counterclockwise to achieve this or turn the end of the vvt unit??
I thought I could just look it up but not so. does anyone have good experience with this type of setup?
Thanks and I hope to help her get this setup soon.
