Anyone have installed valve stem height spec?
Is this all related to the variations in lash? If so, then using the spring seat as a reference plane just gets the top of the stem in the 'general vicinity' of where it needs to go. Is this one stem noticeably taller than the rest?
And how does this relate to that one valve with the large lash that you measured?
Yes, I know I have some stems up to .023 over spec. I'm confused when I go to measure using the Mopar chart, ie.
#1 TDC, check #2In, #8Ex...etc. ALL are ZERO lash and into the preload as I rotate around 90deg at a time...but...#2 Ex is
waaay loose up until #7 cyl is TDC, then its tight. I'm using the Hughes chart...
Column #1 Column #2 Column #3
Position this piston at TDC Adjust the INTAKE valve on this cylinder Adjust the EXHAUST valve on this cylinder 1 2 8
8 1 4
4 8 3
3 4 6
6 3 5
5 6 7
7 5 2
2 7 1
Even using this chart and rotating 90 deg at a time...I get #2 at TDC and 7In, #1Ex are compressing.
I had better luck bumping engine around and watching rockers. I know this Whiplash cam closes Ex quicker so maybe the chart is not the best guide.
FYI...I did realize I had rocker shafts 180deg out and it does seem to have changed original measurements...just trying to understand why, but still have loose rockers that I'll have to use pushrod checker to get proper length.
Holding out cause I know $600 would put Comp pro mag rollers on and solve the issue.
