Changed wear pads, variation is worse

This is where my book will be gold for you guys..

Yes, you must pump the tensioners in oil and then install them immediately before setting cam timing.. Or use the Porsche pre tensioners that are insane money.

These engines will teach you many, many lessons...

Jake,

Any info on the publishing date?

As an update, the tensioners were the problem. Hate to admit I did it, with my background I should have caught that.
I pulled the tensioners one at a time and pumped them up. Huge difference in the tension. Rotated the engine a number of times to be sure the full tension was on the chains, then set the timing.
Final specs on the deviation,
Bank1= 1.59
Bank2= 2.10
I'm Ok with that
@Philmou320 - You're correct in that they are 'suppressors' not 'depressors', much like a shock absorber or lifter. The fact that they are not in dampening mode lets the chain float enough that the timing is near impossible to get spot on.

So I understand that you have to pump them when you put new ones or you have let them for a while bleeding out the oil but when you want to set you timing and they are still on the car, do you have to pump them too?

If the car has run for a while, meaning that the oil is supposed to have filled the tensionners and the visual control of the timing is OK it should mean that everything is Ok, am I right? so Gary, When you checked your timing, were you camshafts perfectly parallel to the seam between the head & the valve cover after -1-the repair AND after a ride?

thank you .
