Intake Manifold Bolt Locations - I need help
 

I have a 1991 Blazer, 4.3l V6, TBI. I took off the heads to fix a lousy gasket. I am in the process of putting it back together. I realized the intake manifold bolts were out of order, I made a template out of a piece of cardboard, but somehow only 8 of the 12 bolts made it into their right place. some are just bolts, others have studs to hold on accessories. That is what is confusing me. Does anyone have a diagram, or a picture to help me out? If you could just type out where they go, I would appreciate it. I went to the junkyard last week, looked at a dozen different S10 trucks, they were all vortec CPI. I need some help guys, I am desperate to get my truck moving again. Thanks in advance for any help you can offer.

So basically some have studs and some dont? I have a 91 tbi 4.3. i can go outside and look for you...I know theirs 1 or 2 at the top rad hose with studs.and i think some where the linkage bracket for the throttle cable etc has them too,not sure. i can look if you need me too.

Yes if you could check yours out for me, that would be great. I want to put it back together once and for all without taking bolts out to rearrange them like a puzzle.
Thanks Chris

Ok for what i could see is this...Left to right if your faceing in front of the engine :

Rightside thermostat housing
left and right side nearest the front
Map sensor bracket,front side.
front throttle cable bracket

I couldnt see the back left side past the coil as a ton of wires and hoses was in the way.

Thanks Chris. Just so I understand correctly, are you telling me the location of just the studs? you mentioned the thermostat housing, I remember that one being there. The bolts/studs I am asking about are the 12 that hold the intake manifold to the heads, 6 down the passnger side, and 6 down the driver side. I'm sorry if i was unclear about that in the first place. Thanks again.

Yes just the location of the studs..and i was calling out every stud i could see on the intake manifold. I dont think the stud on the throttle cable bracket bolts the manifold down,but i noted it just in case.

Thanks Chris. This will go a long way to getting my truck back on the road. I feel a lot more confident now with this information. I hope to finish the job this weekend. Thanks again.

No problem. also remember to add Teflon tape to the bolt threads.

Would it be possible to get some pictures of the bolts and studs that are visible? I want to be as confident as I can be when I get to putting this truck back together. Thanks
