i have a jdm d15b swapped 96 cx hatch. i have replaced the head gasket, the o-ring on the distributor, and the VTEC solenoid gasket. im still leaking oil from the passenger side of the motor. it looks to be coming from right under the dizzy. im a little lost now, what else could be leaking?

Did you use RTV sealant in the inside corners on the gasket?

It really sounds like a leak from around the O-ring.

OEM O-ring? Spread oil on it prior to installation?

DCAR

yes its a honda o-ring. that is the only place to get it. the oil isnt coming from the valve cover. all the oil is under the dizzy...

Is there oil inside the distributor? If so, it's a bad internal oil seal. If not, the culprit is most likely the O-ring.

And there are many available aftermarket O-rings and it is possible to do a bad O-ring install.

DCAR

can those oil seals be replaced? how could the o-ring be leaking, its new?

Former User

Yes

The O-ring can pop out of place or break during installation, especially if you don't oil it.

New is what you had when you bought the O-ring. Used is what you have after you install it.

I had this same problem on my 93 del sol with D16Z6.
After I changed the distributor o-ring there was still an oil leak past the o-ring and I had used a Honda OEM o-ring.
What I did was loosened the distributor and backed it out of the block just enough about an inch to put a seal of silicon grease between the block and the base of the distributor where it touches the block. This was enough to stop the oil seepage. It's been good for over a year now. I got the silicon grease from a NAPA parts store, it's made by 3M. I use it on all rubber gaskets and o-rings now.

The internal oil seal is often neglected. After the outer o-ring is replaced, this is the only part left where oil can leak through the distributor.There is a small hole where the lubricating oil passes to return back to the engine. It can be easily clogged and so oil will accumulate near the oil seal. Cleaning this would prevent accumulation of oil but still sufficient to lubricate the shaft and seal. Oil leakage can be prevented or reduced depending on the condition of the seal.

no the o-ring still looks good. i have had it off a few times to inspect and no rips or anything. if i have oil inside the dizzy whats my options on fixing it?

There's nothing wrong with using a this film of form-a-gasket in addition to the O-ring, but it sounds like your internal might need a little inspecting.
