    I did VC gaskets and intake gaskets on my 91. Everything went pretty smooth besides bolting the intake back down. Can anyone show me a picture or explain to me which bolts must be loose in order for the intake to set flush down on the engine? I've tried my best but I can't seem to make it happen. Thanks again guys!

    You have to loosen the couplers on all the intake runners so there is enough for the intake to be slightly flexible. Then you put the intake back on the head and get it to sit flush. Make sure no wiring or small vacuum hoses get in the way on the back (crushed a vacuum hose and could not seat the intake properly my first time). Tighten the bolts and the clamps on the intake runners and you should be good to go.

    You can see the couplers are the black pieces with the hose clamps on the intake on this dumb video I got in a google search-- fast forward to 2:17 for an intake shot

    I never had to loosen anything to get the intake plenum to sit back flush. Though I will agree you need to be very careful not to let anything fall down into the holes of your intake and also not to crush any wires or vacuum hoses.

    It's hit and miss putting it back on with everything still tight. To get a good seal at the gasket it's good practice to loosen the couplers just to be sure. I've had it not seat flush a time or two trying to short cut it.

    Update, so I believe I have the Intake back on flush. The culprit was a crushed vacume hose. Now I have a new problem. Ive done lots of reading but any more advice would be appreciated before I get back at it. My car is running really rough. Has hard starts and just a rough sound coming from the engine. Not really a knock or tick, just grumbly. Also when,I hit the gas it bogs down.. I hear what seems to be a vaccume leak, at the left of the Intake/engine. I'm gonna spray everything with starter fluid tomorrow see what happens. Ive looked over my work a few times now and can't seem to figure out where i went wrong. Everything seems connected. Here is a list of what I replaced: VC Gaskets, all intake gaskets, plugs, wires, thermostat, upper radiator hose, plug well rings. I also replaced the short wire from the sensor on the top left of the IM with plugs on either end going to the battery. The new wire is bigger gauge, possible problem? I have not tourqued the Intake bolts just hand tight then a little more. I'll do that first thing tomorrow. As always you guys are great and I surely appreciate!

    Yeah, you have to go back and recheck your work. You replaced the hose that got pinched by the intake?
