Pontiac 6X-head problem

[njsteve]

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: StealthBird</div><div class="ubbcode-body">Also, if you haven't worked on a Pontiac before, make sure you use the rubber o-ring at the front of the intake to water pump, and use some silicone to seal it. Lots of guys forget that, or don't use silicone/gasket sealer along with the o-ring, and they end up with a puddle of anti-freeze on their valley pan cover. </div></div>

Quite right! And make sure you install the timing cover/waterpump housing before you install the intake. The correct procedure is to have that timing cover in place, then put the rubber O-ring on the front of the intake. Then set the intake in place. And this is the important part: The first bolt you tighten is that really long, horizontal timing cover-to-intake bolt that pulls the intake up to the timing cover and compresses the O-ring. Then you can tighten up the intake mounting bolts. [img]<<GRAEMLIN_URL>>/scholar.gif[/img]

Welcome to the wonderful world of Pontiacs. So what's it going in????

be carefull not to pull it too tight as you will crack the intake or timing cover.I have found to hand tighten the rear intake bolts and then pull the intake to the timing cover.This will keep the rear of the intake from lifting and causing miss match of the intake to the cover.Tom

Thank you guys ! I know we had a leakage problem (exhaust gases) with the castiron manifold after putting the 6X-heads on the engine. So I thought it was a manifold problem since the intake was older than the heads and I assumed the aluminum intake would cover that &quot;hole&quot;.
It´s going into the 1971 Le Mans that we have, the one that had a RAII engine in it when we bought it. It´s in &quot;members rides&quot; long ago.
Thanks again for your input guys !
