Hey everyone

Im just about to finish my motor and need to do a clay test to check the piston to valve clearence but the only this is how do you engage the V-Tec when testing?

Thanks

yeah, as sayd in the link, just swap the vtec locking pins around

 

thanks for the link but this is the part i dont get you must dissassemble the rocker arm assembly for the cylinder that you are going to test on (#1 cylinder) and switch the VTEC pistons in the rocker arms so that it locks the VTEC rocker in place. You don't need to dissemble the entire head, just slide the rocker shaft out far enough so you can remove and install the rockers on the #1 cylinder.
With the rocker arm pistons swapped, you will be testing the clearances when the valves are on the high cam lobes and not the low ones. This is very important, since when VTEC is engaged, that is when you have the closest piston-to-valve and valve-to-valve clearances.

how do you switch the vtec pistons in the rocker arms?
