I was reading Bambam's "how to build a realiable lsvtec/b20vtec" and he said rotate the entire assembly. I don't get that. As this is my first build, when should i know when is the right time to rotate the assembly while in the build???...Please help guys...Thanks.!

 

huh?

i think you need to go back and read what he said.

 

maybe......
Balance the rotating assembly?

 

or maybe to rotate it after installing each piston..

 

I think he meant to rotate the assembly to check for binding or clearance issues. IE, after you put the bearings in No 1 conrod, give the crank a spin to make sure it rotates freely.

 

rotate to make sure everything is rotating smoothly without any type of interference, also do this after you've installed the head w/the timing belt.
