This seems to be a common oil leak / gunk buildup area on honda engines. Im just guessing where its coming from the valve cover gasket area? Any other places to check before I go about installing the new gaskets?

Replace your Positive Crankcase Ventilation (PCV) valve, too. If it's never been replaced, it might be gummed up and causing excess pressure to build in the engine forcing gaskets to bulge and leak.

While you have the VC off, you might as well check the valve lash and adjust if necessary, and change the spark plugs.

Valve lash adjustment and spark plugs are the plan. Actually looks like it's the distributor leaking. Not the valve cover. But still gonna replace that gasket too because I want to do the lash adjustment.

Any recommendations for an aftermarket dizzy? Hondas are like 3x the price

There is an O-ring on the distributor that you can replace. Unless the shaft is bad I'd replace the O-ring.

It'd be better to rebuild the distributor with OEM parts than to buy an aftermarket one.

Well I can see that it's leaking. Should I test if the new o ring fixes the problem?

To rebuild the dizzy order parts thru Honda? I've never rebuilt one. Not sure what I'd need to order

There is an internal seal on the shaft, as well as an external O ring.

If there is oil inside your cap, it's the shaft seal.

If it's just leaking out, replace the o ring.

if nothing else is failing, ignition wise, in the distributor, you don't need to replace anything else.

- use a wire brush to scrape the Calcium buildup
- spray some engine degreaser to remove the caked up oil on the block
