Chain Ramp Inspection's
 

Can you inspect your chain ramp's or guides using a camera,..you know the type that can snake thru the spark plug hole,.(once you remove the tube ),.? Thanks Frank

I don't think so... Anyone else?

I think it would be very difficult. Your cam deviations are a good indicator.

NewArt my numbers are bank 1 = 8.6 bank 2 = 3.6 Ill admit numbers not taken as JFP said to,.which I will do it that way this weekend but it was warmed up ,..just not driven around.! cant wait to double check them !!

doing tensioners this weekend to I hope,

Not possible.

8.6 would indicate worn ramps. You would probably get a code before too long.

Usually around 12 degrees.

Wouldn't the deviations be a result of numerous points of wear; the most significant being vario cam tensioner/phasing pads. These are actuated into the chain for most of the rev range.
