I'm currently working on a CA18det motor changing out heag gasket and front/rear main seal. the only problem i have is,the FSM that i DL from the web was missing a few key pages.head bolts torque paterns and specs on re-installing the head.

So can anybody please help me or pointing me in the right direction, to fine the torque patern and spec on re-installing the head?? please.I've tried searching here but came up empthy handed. Thanks in advance.

PS: BoostBoy. any input from u on this matter will be great. thanks C

The front crankshaft seal is going to be a bit of doozy! And no FSM is going to help you overcome the amount of headache involve. The FSM's torque specs and tightening/loosening order mainly pertain to those gaskets that are of stock composite materials. Perma-torx gaskets are a two stage tightening scheme in which you will tighten all bolts to around 35 pounds per square inch and finally securing the bolts with around 80-85 pounds per square inch. This is the method I use on all the motors that I deal with and it has never failed me. If there's any doubt, use the order the FSM prescribes.
