    Help installing camshafts

    Hello Everyone I have just recently bought a 1996 Seville STS off ebay for $1200.00. I did not do my homework before buying,seller said engine had blown headgasket. Engine was already torn apart. I am trying to stay on a low budget with this car, what I would like to know is 1) what are the torque specs and the sequence for torquing them are? 2) what is the proper way to tighten down the cams, and the torque values for them? Any info would be greatly apprec.

    Re: Help installing camshafts

    You really should buy the FSM. There is enough to reference that it's pretty hard for someone to give you everything you'll need. Check EBAY. We used manuals a year off and they covered everything we needed.

    I think 96-98 are very similar. Someone who knows for sure can chime in.

    Depending on where you live the public library may have Alldata access. I know Phoenix and San Diego do.

    Some things have been covered in threads. Cam timing and head torque among them. You can search and find those threads.

    You probably do not have to do anything with the valves or cams. Leave the heads alone unless you see something obvious. The N* has really good heads, they don't warp or burn valves.

    Zonie77 Thanks for responding I was hoping to hear from you,I have read a lot of your threads. Do you think the heads need to be checked for cracks and milled for warpage? The gasket blew on the back side between the first and second cyl from left to right. Thanks

    As I said, unless you see something obvious they should be OK. The majority of guys who did their own did not do anything to the heads except clean the gasket surfaces.

    Don't use Scotch Brite pads for anything to do with machinery. They are the worst possible contamination.

    I'd just check the gasket mating surface with a good straightedge and run with it.

    Re: Help installing camshafts

    This is why an FSM can come in handy... if nobody else replies I will take a look tomorrow (although mine's a 95 there *should* not be a difference,) my info is at my friends house/garage.

    Re: Help installing camshafts

    The FSM says 22ft/lb + 60deg + 60deg + 60deg.

    That's 22ft/lbs plus 180 degrees in 3 steps. I think that was updated to a slightly higher figure though.

    Mark the bolts at the 22 ft/lb step so you can verify the turns. Use a sharpie/marker.
