You will have to remove the distributor and replace the gasket. Next and most important is the PCV system. The PCV valve is in one valve cover and a fresh air tube in the other. On the fresh air side place your thumb over the pipe and see if you have a suction with the engine at idle. If not then replace the valve and recheck. If you still do not have a suction then remove the pipe and be sure it is unrestricted. If so then clean it out. The PCV valve keeps pressure from building up in the engine. When it does the pressure goes to the weakest spot.
It is at the rear of the engine and has the plug wires coming out of it.
behind the engine you'll see a black circle with 7 plugs coming out of it. that is the distributor cap. take the cap off and you'll see the rotor.
there is a gasket that goes under the distriburator that needs replaced.
get a testlight ground it to the battery and turn the switch on and check the hotwire coming out of the module Also if you can remove it from the distributor you can take it to a good auto parts store and they can bench test it for you.
located in the distributor itself, follow wires coming from coil to distributor
On top of the distributor. The thing with all the plug wires coming out of it.
counterclockwise
A vacuum leak nearby. Distributor shaft & bushings are worn and the rotor is clipping the distributor cap inside. Spark arking inside cap.
This can be tricky. The base of a distributor is sealed with several "O" rings and to replace them requires removal of the entire distributor. A shop will charge no more than an hours labour for this. Or a "Quick" fix is to loosen the bolt securing the distributor and lift it out slightly and the wipe all oil away from the mating surfaces. Then use a heat resistant silicone and apply a small amount to the mating surfaces, drop the distributor into place, secure the bolts and wait several hours and then start.
The spark travels from the coil to the distributor then from the distributor to the plugs. So if you have spark going into the distributor but not coming out to the plugs, I would blame the distributor cap and rotor being at fault.
your coil's got a posative and a negative... Positive is Ignition hot and the negative connects to the distributor
Yes, it should be located towards the back of the block, and can be identified by the ignition wires coming off of the distributor cap.
