How do you replace a starter on a 1987 Chevy 305 V8?

Plug and play my friend. Disconnect battery. Remove all the wiring (positive(red), negative(black) wires and another very large wire located on the back. with all wires removed ( remember to take note as to where they all came from!!) Remove the bolts attaching the starter to the car and holding the starter securely in your hand, wiggle er out from the flywheel and the mounting brackets on the engine.

Take the new starter and observe as to where exactly all the wires would go by remembering where they all were on the old one.

When putting the new one on, i like to attach all the wires first then put it in EXACTLY the way the old came out, screw in bolts and make sure it is tight. aluminum gaskets are appropriate and will come in the box with the new starter.

Do you have to use the egr valve on 305 or could you just block it off?

No you need the EGR valve as these gases need to be vented from the crankcase. An EGR unit that has failed will cause your vehicle to run rough and use more fuel. The three letters in EGR stand for " Exhaust Gas Return". If your valve has failed it is best to replace it.

+_+_+ Actually the above answer is wrong. EGR valve system is used to add a small amount of exhaust gas to the combustion chamber for emission purposes. It also keeps the temperature of you engine lower. It is not active at idle or at WOT (wide open throttle) when they fail they put the exhaust gasses in the combustion chamber at idle making it run rough. IT IS NOT NECESSARY! Block off plates can be purchased or created. +_+_+

+_+_+ PCV Stands for Positive crankcase ventilation and that is a small device in the valve cover. +_+_+
