[carolinagreenhead]

Thanks Chris- will look into those. Pretty in-depth, and a couple of them vary from one engine model to another (so may not be feasible).

[BrownTrout]

Very useful info. Thanks Don

[BudT]

Good stuff thank you Don. Can you please add Plenum bolts. My manual references 100 and 120 inch pounds I'm sure it is pre and post 2003 but not sure which is which. Thanks again.

You are correct- there is conflicting info in many of the manuals. 120 lbs/in is best suited to all "air-handler" type intakes (down-draft throttle body models). Added to list.

Would like to request, Compressor pully screws.
Thanks-

[EuropeanAM]

Air compressor pulley screws added.

Hello, is it possible to update torques for the rod caps, mains caps and any other internals?

Hello, is it possible to update torques for the rod caps, mains caps and any other internals?

These items are internal components, and are really beyond the scope of a blanket "cheat sheet".

A Factory Service Manual should be utilized for this type of extensive repair.

Wayne... you've got a PM.

[dkennimer]

Maybe alternator for those changing belts.

[EuropeanAM]

Maybe alternator for those changing belts.

V- Belt driven spec added.
