Timing and TDC ??? Putting in Distributor

I am about to take my distributor out. I am putting a new intake on. What valve from the #1 cylinder should be down be down, exhaust or intake? The rotor should be pointing to the #1 cylinder too, right. Thanks

Re: Timing and TDC ??? Putting in Distributor

When you are refereing to timing, you're refereing to TOP DEAD CENTER of the compression stroke, so there shouldnt be any valves down at the time. The distro will be pointing wherever you happened to turn the car off.

The easy way to do the intake is to pull the distro, but mark where on the distro the rotor is pointing. When you put it back in just make sure the rotor is pointing to the part you marked before you took it out.

It's usually easiest to bump the starter over until the rotor points to the firewall and put a mark there. You can then take it out. It's a good idea to mark the body of the distrbutor here also. Then put it back in with your two marks lined up and it should work. Basically you're putting the distributor in - the exact same way you took it out. Make sure you don't turn the motor when you change the intake. If you do, then you will have to retime it, with number 1 at TDC. And by the way at TDC firing the number one cylinder, both valves will be closed.
