Question about 1986 Chevrolet Nova
Posted by Anonymous on
It wasn't the oil level. Mine started ticking around 14K and it still ticks like crazy at 168K when the engine is warmed up and cruising. Goes away under moderate acceleration.
There is a thermostatic flapper valve in the exhaust manifold that is likely the source of the ticking when the engine is warm.

It may be a coincidence but try replacing the oil pressure-sending unit if it does not change try changing back to the original oil

Try Autozone's website, you'll have to create a free user account, but they have wiring diagrams. The colours are indicated by letters on the schematics.

The Haynes manual is detailed enough to get you through the job, or you can create a free account at Autozone and they have an online manual which also covers this task. I can go through it step by step if you want, but essentially I'd just be regurgitating the information available from these 2 sources.
It's not a particularly difficult job, just a bit cramped, and make sure you have all of the necessary tools to hand so that you don't have to keep climbing out from under the vehicle, that tends to get old really quickly...

I'd personally start by checking the basic ignition components; spark plugs, spark plug wires, distributor cap and rotor. If any of these items are damaged, worn or just no longer up to specification then they're likely to be the culprit. Mine just went through a spate of stalling and wouldn't restart because the wires were no longer insulating properly...weak spark, wouldn't ignite the fuel.
Let us know if this helps, and if not try to provide some more detail regarding the conditions when this is occuring.
