Re: video- 07+ 400-Valve Clearance Inspection
I have watched the #2 video 3 times, I have gotten to the cam lobe and the tappets and am trying to measure the clearance.
I have set the TDC to the beginning of the notch, the middle of the notch and the bottom of the notch on the right side.
I am trying to measure the intake side (i.e. the closest to the seat). I have a mirror so I can see the feeler gauge, have light on the tappet and cam and can see the cam lobe and the tappet top clearly.
I can not possibly be measuring correctly:
I slide the feeler gauge in from the exhaust side of the intake valve, I see it go under the cam, until it gets to about 3/16" of the wall of the tappet closest to the seat. There it will not go under the cam lobe and get all the way across the tappet top. I think this means I have the crankshaft rotated a couple of degrees to much. However the rotating TDC indicator on the right side the mark is right at the very first part of the notch opening you use for TDC alignment.
I have tried from .008mm all the way to .300mm and can slide most of the feeler gauge under the cam lobe to about the 3/16" from the wall of the tappet bore.
I have tried the middle of the TDC mark and notch, I have tried the lower (to the ground) part of the notch and the mark.
There is something fundamentally wrong with what I am doing or the way I am doing it.
When I pulled the plug the color was a light tan, the electrode was worn some (about 1/2 of the orgional electrode) indicating that the ecm is working the mixture properly and the combustion is happening correctly. I also think that also means the valves can not be far off if any, but I am having a heck of a time getting that measurement to validate it.
I need some ideas. I will leave the scoot apart until I figure out how to do this.
