Please advise on all the torque settings for pistons, mains, top/head, tappets (hot or cold) for the car listed above, etc?

I attached the torque specs for the complete engine. It looks like all the items are in there that you are looking for. If not let us know and we can find it somewhere else in the manual. Thanks

I thought they were in there but maybe I am not understanding what you are referring to. Let's take them one at a time.

1. When you say pistons, are you talking about the connecting rod nuts? If so, that is 24-26 ft lbs.

2. End mains - I figured you meant Crankshaft bearing caps - 42 ft lbs.

3. Cylinder head - This is listed as cylinder head retaining bolts which is 16 ft lbs + 82 degrees of rotation starting at the center bolts and working your way to the outside bolts.

4. Intake manifold is 89 inch lbs. I guess I am not sure what you mean by hot/cold.

I think all these are on the documents but again, if I am not understanding something then get me a little more detail on what you are looking for. Thanks
