How did you adjust the valves? What kind of problems are you having?
Are you sure you are on the proper spot on the cam?
Realistically the lifters should bleed down.
Try turning 1/2 let it set for 10 minutes and see if you can turn pushrod. I suspect you are not allowing lifters to bleed down.
Accordng to service manual and parts catalog they are the same. What I am thinking is when you are tightening you are going to tight.
Adjust until you cannot move the pushrod up and down instead of til it wont turn. then go 1 turn. My manual states 1 turn after the clearance is removed.
I looked up rocker arm part numbers and spring height specs. The ratios and spring heights are the same 91 and 95. The part numbers are different and I cannot determine the change
I can opt out and see if another expert can help
I always adjust the valves when the engine is idling no matter if I give them an initial adjustment when it's not running or not. What I would do is start off with 1/2 turn down from zero lash, then while the engine is idling back off each adjustment nut 1/8 to 1/4 turns until the lifter begins to clack then tighten back down 1/8 to 1/4 turn at a time, pausing of course, until the noise goes away. That would be zero lash, then go down another 1/2 to 1 full turn depending on the mileage on the camshaft, with 1/2 turn being anything nearing or over 100,000 miles and 1 full on anything under 50,000 miles.
The spring tension, I don't believe really matters, but the rocket arm ratio I believe should. I would think that you would have to adjust your thinking or specifications for how much of a turn or adjustment there is for the valve and lifter since of course it takes less travel of the valve lifter lobe to equal the same distance of valve opening.
If it's a 1.5 times ration rocker arm, I would naturally think that you would divide that 1 full turn down by 1.5 which equals 0.66 turn.
Let me backup here. I believe adjusting the valves has to do with putting the lifter plunger down into it's center of travel, so even if the are different ration rockers, the adjustment will still be the same.
If your valve springs are starting to compress and valves open, I might come to the conclusion that you are not on the flat side of the camshaft. You never did say on the compression stroke when you said tdc, so maybe that is your problem, you have to distinguish between tdc exhaust and tdc compression stroke, then do those adjustments.
