Intake manifold re-seal 4.3L

    Hi everyone. My 2000 Chev 1500 4.3L V6 RWD has a coolant leak at the front of the intake manifold. Is it better to get the whole seal kit that includes valve cover gaskets and everything else or just the upper set which will only do the manifold. I'm asking because the whole kit is double the cost. I will be doing the repair myself. Oh, and if anyone has any tech tips for this job let me know. And yes the 4.3 does have coolant flowing through it. soon enough I will upgrade to a V8, but not yet. Thanks for any and all your help.

    is it the upper intake gasket or the lower?

    It is the lower gasket. I think I have decided to buy the whole seal kit. It's probably best to change all the gaskets and o-rings while I have it apart. Spending the extra money will mean base model shocks. Oh well, at least I'll have peace of mind in it's reliability.
