2001 Boxster S Engine Noise

[Wilson01S]

I found an online manual for removing and replacing valve tappets-

In the steps it says "Basic camshaft adjustment of cyl bank 1-3 the groove in the camshaft must face outward toward the cylinder head cover"

I have that done.

Now it says "basic camshaft adjustment for cylinder bank 4-6 groove must face inward toward the crankcase"

Are they referring the marks lining up like that at one time? Or should the mark for 1-3 be facing outward- make your adjustments to timing for bank 1-3. Then when you are ready for bank 4-6 spin the engine 360* relock the crank and check to see if the groove for 4-6 is now inward. If it is then make your adjustments?

If that's the case then I am 360 out on one bank, and would make sense why the exhaust manifold for 4-6 isn't getting warm and its missing on 3 cylinders.
