Removing intake, any tips?

[LSUfan71]

Is there a secret to remove an intake off a 20-year-old engine?

I'm replacing the intake gaskets and I'm at the point of removing the intake from the block. I've tried inserting a thin paint scrapper between the intake and the block to free it up a little but it's not gettting the job done.

Any tips/secrets would help.

There are only 8 bolts, right?

I cannot remember the number of bolts off the top of my head. Did you remove the distributor and egr tube already?
I had to use a pry bar carefully to lift mine off since it was stuck so well.

Yes, there are only eight bolts. Assuming that you've already pulled the distributor and all the other lines/hoses, you also need to remove the driver's side valve cover, disconnect the EGR line from the intake, and loosen the accessory drive bracket so it hangs forward far enough for the AC compressor mount to clear the intake manifold. With the driver's valve cover off, you should see a small tab near the intake/head mating surface that you can use a large screwdriver or small prybar to gently pry up on the intake. It should pop off with some firm pressure, or at most a pop or two with the heel of your hand.

Edit: This is all assuming that you have a Vortec engine. If you have a TBI, as your sig suggests, disregard the above post. TBI intakes have 12 bolts, and you should only have to disconnect the rad/heater lines, vacuum hoses, fuel lines, and all wire connectors in addition to pulling the distributor. Same procedure as above with the screwdriver/pry bar. Be sure you have ALL the intake bolts out, though.

Dist is off but I left the egr on, I thought I could leave it on.

Ok, I didn't remove the driver's side valve cover. I know it needs to be remove for reinstall tho. I'll get back to it in the morning and remove the drvs valve cover first. Thanks for the tips.

This Fel-Pro image of the MS93317 intake gasket shows 6 bolt holes on each side, maybe I missed 2 bolts in the rear on each side?

Entirely possible. The two in the center can sometimes be covered in oil/trash that builds up in that area. Double and triple check before prying on it.

OK, 88-95 has 12 bolts, 96 & later have 8 bolts. My rear 4 must have gunk covering the bolt heads. I suppose it would have helped if I had read the manual already in my possession. How do you guys put up with people like me? smh

Yeah step #1 make sure you remove all the intake bolts.

Here's a write-up I did on mine, also a '94, a while back...tons of pics and details.

Cool, thanks.

Intake is off, got a good bit of cleaning done. Ridiculous amount of sludge inside. I'm too embarrassed to post pics.
