got a hold of them..

they said take the HYD a-juster out and put in a vice, to remove oil presser.
i did this and the valve is now closed.
ill see about some photos.

they said im one of 3 people that this happened to.
after that they figured it out and started fixing the issue before shipping the head...


talk about drawing the the short straw.....

I'd bet a million bucks there is nothing off with that rocker position at all, more likely the new valve seat put in too low, probably not a new head. Rocker stands are generally machined all at once. VERY odd for one to be off like that.

You can collapse a hydraulic lifter with a simple c-clamp. You ALWAYS collapse lifters going into an unknown quantity new rebuild, good way to bend some valves.

well got the pan/head back on, compression tested it was all 150/180, started up.

seems to stumble at low rpms, better as revs go up.

my INNOVA 3140 scan tool "not the dash trick" shows no codes.

timing? senser?
to much difference in comps piston to piston making it shake a little?

think ill try and run it 15 min or so, see if it puts a code out after it heats up.

pulled the timing cover found it off 0.25"

put it back one tooth and that makes it 0.25" the other way.



one way it runs smoother but the rpms are jumping up and down a few 100

the other way it stays fairly steady but its all most like its missing, revs better at higher rpms.



i thought timing marks are meant to line up????

any ideas? other then the Z one....
