[QUOTE="AfricanSnowOwl, post: 16492649, member: 168923"] I got the lower installed today. Used "the right stuff" gasket maker for the front and back(skipped the rubber gaskets), and also put a ring around the coolant ports. Followed the torque sequence, and now I'm just giving it 24hrs to dry before I try starting it up. I did notice that the rubber PCV grommet on the back of the lower intake was significantly loose. Loose to the point it would just fall out if you turned the intake upside down. That could have potentially been something causing my problem, so I put a ring of rtv around the base of the grommet to give it a good seal. I also apparently stripped out the threads on the heater tube connector, so I'll have to figure out a way to make that work. Seems like I can rig some hoses and a 90 degree connection up pretty easy. Don't feel like spending $100 on a new one from LMR. When I initially removed the lower intake manifold, all of the bolts were pretty loose. Loose to the point that I could've used a nut driver to remove everything. That plus the fact that it was free to move around with no give whatsoever after the bolts were out leads me to believe that there wasn't a good seal between the lower manifold to the heads. I'm really hoping this fixes the issue. Honestly if this doesn't fix the issue, a drastic change in the engine/tranny swap is in the very near future. [/QUOTE]
