Default Question about changing intake manifold

Hello, I just changed my intake manifold yesterday and I did a lot of reading about it before I changed it out. After I got it tightened down I thought of something and was wondering if I did it right or wrong. I was thinking if I needed to put RTV around the distributor hole? I only ran the bead across the china wall and around the water inlet holes. So did I do it correct or did I mess up and have to re-do it? Thanks everyone

Adam

You did right. There should be a thin paper gasket under the distributor. Otherwise, RTV just goes across the ends and around the water passages. A good intake gasket set handles the rest. BTW, a little sealer on the bolt threads prevents oil from seeping up and pooling on the intake. Not much is needed there and it seems that only certain bolts are open to oil from underneath.

Great ! I do have a paper gasket to put under the distributor when I install it back on the manifold. How hard is it to set the timing because I did not mark the distributor when I removed it But it only go's on one way really because of the tachometer(I think that is what it is) faces one side. I bought a timing gun just in case I need it. My brother told me to get it close to the original install and try to start the car... if it starts and sounds good then its ok ... how true is that? Thank you

Turn the motor over to get it to the top dead center mark on the balancer. Watch the valves on the #1 cylinder to make sure that they are both closed when it is at TDC. Install the distributor with the rotor pointing to the #1 cylinder. Make sure the #1 spark plug wire is in the same spot as the rotor tip. This should get you close enough to start the car and time it properly.

mostly If the valve covers are on, you can just pull the #1 spark plug, hold your finger over the hole and bump it until you feel the pressure. It'll start a lot easier at 8-10 degrees BTDC than TDC.

Note that once you get everthing aligned you'll probably find that the distributor shaft won't fully engage with the oil pump intermediate shaft and the distributor won't drop all the way. Just pull the distributor up and turn the rotor back 1 tooth...put it back in...and bump the engine until it drops. Double-check your timing and off you go.

Many intake gaskets no longer require RTV around the water passages - make sure you read the instructions next time around.
