Replacing Intake Valve Retainers
Is there a sequence also in tightening the valve cover? I have received all the retainers and keepers just waiting for the valve compressor and compression gauge and more very helpful information from everyone. Again thank you.
The timing chain is on a separate sprocket which drives the camshafts, so you don't need to set the timing anywhere special to remove the cams, timing only needs to be set during installation. White line on crank pulley aligned with the triangle on the block, and the cam sprocket and cams aligned.
The recommended tightening pattern is done in "two or three steps" starting, indeed, with the center bolt on the intake side but isn't exactly what I consider a "star" (like lug nuts). Pretty easy to just torque to the diagram. I'm assuming it's important since it's specified.
Page 6-23 in my 2007 shop manual; page 6-54 in the on line 2003 PDF manual. Torque is technically 8.7lb-ft
but that's just the math based on the actual metric 12 n-m spec.
The main consideration seems to be tighten the center, then the ends in stages and don't over-tighten.
