First time replacing intake manifold gaskets

[johnswie]

Great info here @johnswie. Easton did his when he was 14 and it was not that bad at all, and the timing was the easiest part. You can do it.

Cool pics Randy, thanks for the vote of confidence!

Stock cast-iron intake or aluminum intake?

Edlebrock aluminum

Edlebrock aluminum

Many recommend a non-steel core gasket like the one Edelbrock sells.

Does anybody know what this is called or what it does? It was on my intake but nothing attached to it.

It’s part of the hot air choke on a Quadrajet. The choke mechanism has a couple small tubes that connect to that device, and it pulls air through it to heat and operate the choke.

It’s not needed if you have an electric choke. IIRC, my Edelebrock intake came with a choke block-off plate for the fitting on the intake.

I use Fel-Pro intake gaskets...throw away the black rubber front and rear seals and run a bead of Permatex RTV silicone gasket maker instead.

Distributor timing has already been covered, I will add though, it really isn't as scary as it may seem.

Easton used no gaskets front or back just permatex “right stuff” and it’s been perfect going on 2 years

Wanna sell it? I'm sick of my electric choke.

Make sure you mark cylinder 1 wire on the cap and you know the firing order so the wires go back on in the right places. Rotor turns clockwise.

I got a couple wires swapped on mine recently. Motor ran, but ugly. I'm always amazed at the resilience of these motors when I make a mistake like that.

Invest in a timing light w/ tach and dwell, and a vacuum gauge. You won't be sorry.

Look forward to hearing your progress. Mine has evidence that PO used _way_ too much RTV and probably needs to be cleaned up.

OP, when I was first learning my old man taught me to write information on the inside of my hood. That way I could pop the hood anytime and be able to see firing order, the rotation of the distributor, part numbers for oil filters and oil capacities and other specific information if I forgot. It was very helpful in the beginning. A light coat of clear over it will make it stay longer.

Also, silver Sharpies show up on black parts really well

I use a white paint pen to write on the black NAPA gold or Wix oil filter ends the date and mileage it was installed. This has helped me to remember when.

Ah, that makes sense! Thanks for the info.

Wow lots of great articles in there! This should help a lot

So everything is finally hooked back up. The biggest issue I seemed to have was that I couldn’t properly fit a socket in between some of the valleys on the intake. I torqued the bolts done as well I could with a smaller wrench, but not sure if it’s to spec. The bolts came off pretty easy, so I feel like I had it tighter than before. Anyways, after an oil change I started it. Ran rough and had a new loud sound I couldn’t identify. Like a loud tick? Adjusted the timing. Seemed to idle well but still the loud noise. After warming up it seemed to go away. But comes back once in gear. Drove it very briefly and seemed to drive fine. Any ideas what this could be? Maybe this will go away (wishful thinking)? I’d post a video if I could

Hopefully you didn't drop anything inside. I can't imagine a tick from an intake change. Check your plug wires and distributor cap is on correctly.
