Distributor oil leak need help!!

[frank]

Distributor oil leak need help.
Where the distributor and the block meet leaks oil when I get on it. I’ve taken the distributor out and took light steel wool and cleaned the bottom of it. In the block side I did the same until it was spotless. Replaced the gasket tightened it down and it still leaked. I then did the same and put 2 gaskets it still has oil pooling up. There are no groves/gashes that would offer a hope to leaking oil. Need some help

I assume this is on a big block? It's most likely that the valley pan is leaking but if you are sure it's the distributor, check the base where it goes into the block and see if it has an 0-ring groove.....

Do you have good crankcase ventilation? I'm wondering if your crankcase is being pressurized and pushing the oil out.

No reason to get nasty, I'm the one that didn't add the correct information. Go figure I forget to mention the most important information. It’s a 1969 Road runner 383 4 speed magnum, also see attached for exact location of oil leak. I really need help with this; it’s a pain in the ***.

I would think it's the o-ring gasket too. Has that been replaced already?

 

[frank]

As indicated in the original posting, I’ve changed-out the “O” ring gasket, it’s still leaked, then I put 2 of them on top of each other and it’s still leaking.

Uh, who got nasty? Did I miss a post that got deleted or is it one of us? Anyways, if the base of the distributor just below the base flange isn't grooved, it takes a flat gasket but if it is grooved, then it takes an o-ring to make the seal. If it takes an o-ring, make sure the groove is good and clean and the right size o-ring is used. I've seen ones that are too small in diameter installed before. If it takes a gasket, a coating of RTV may do the trick.....

I don't know how you could put 2 of them on top of each other, if you are putting them in the groove machined into the distributor. As was noted above, you may have an O ring that is too small for the application. It may fit into the groove, but not be thick enough to stick outside of the groove far enough to seal against the block.

I would guess the rubber o-ring on the shaft is leaking. If it is, the oil will wick right through the paper distributor gasket. Also check the valley pan for leakage.

Stick with me on this…I’m stilling trying to figure out the verbiage. It’s not and “O” ring there is no groove, it takes a flat gasket. At idle there is no indication of the oil coming out it seems to be more prevalent when I drive it. I’m in the process of replacing the, distribute hold-down clamp maybe that’s the problem (I’m not overly optimistic about that). What I meant to say about putting 2 on top of each other was that I put 2 distributor mount flat gaskets on top of each other not 2 “O’ rings.
Stick with me guy’s I need your expertise on this.
Thanks, Frank form Delaware

Do you have good crankcase ventilation? I'm wondering if your crankcase is being pressurized and pushing the oil out.

Did you check the issue mentioned above? If your motor has excessive crankcase pressure it will find a way out of the motor. Make sure you have a working breather on the valve cover.

crankcase ventilation?

Not sure what to look for in reference to crankcase ventilation.
You’re Input..........Did you check the issue mentioned above? If you’re motor has excessive crankcase pressure it will find a way out of the motor. Make sure you have a working breather on the valve cover.
Response: "working breather on the valve cover." I have a chrome valve cover cap that has a hose to the breather on top of the carburetor. Do you think I should replace it? I have chrome valve covers (if that matters). Do you need me to take a picture of the valve cover w/the breather cap?

Thanks for your help…..

I have some pictures of my car on my profile, you can see the cap there

 

[sicksatellite]

do you have a PCV valve in one of the valve covers? if so, check to see if it's plugged

 

[frank]

Responce

This past Wed. when I had the car out (and stepped on it a little) I returned home, lifter the hood and saw the PVC Valve was out of the valve cover, I guess it was blown out. The one that’s in the car now only has 1 end on it on top, not 2 as your photo shows.
My vacuum is connected to something else.

 

[Stumper]

That could be your problem then. There are two typical ways to evacuate crankcase pressure on a stock car. One is the "breather" mounted in one or more of the valve covers that allows pressure to vent to atmosphere. The other is the PVC valve that actually uses engine vacuum to pull the pressured gases out and return them to the intake. If your PVC valve popped out (from pressure build up) it could be that it was plugged and not operating correctly - or maybe that the vacuum line pulling on it was choked off (same effect).
Either try soaking the PVC valve in gas to get it clean - or just buy a new one, and make sure the vacuum line (s) connected to it is pulling a vacuum - into the intake.
Also make sure your breather is clean and flowing.

 

[frank]

In reference to your last posting

Following your suggestion:
--Will replace the PVC valve
--Check vacuum line, make sure it’s pulling
--Check breather filter is clean

I also attached more photos for you to look at, maybe there’s something out of place?
I’ll check in with you tomorrow.

Thanks, Frank for delaware

From what your pics show your engine looks like it only has a PCV and not a crankcase breather. If you replace or clean your PCV and still have the problem try a valve cover breather, you can get the type that replaces the oil fill cap .Your engine may be creating more pressure than can be relieved by the PCV alone hence the pushing out of the PCV and the oil seeping out of other places. Does your oil dipstick push up in its tube?

 

[frank]

Thank for your help, this $%#* thing is turning out the be a disappointment, but I guess its part of the package. I have a breather (on top of the carb) with a hose that runs to the oil cap, so I have that covered. On the issue with PCV I’ve replaced it but not with the one that sicksatellite posted with a photo on 22April. If I can find one like that where does the small top opening hose hook up to? Also, yes the oil stick comes out as well as the PCV (from the valve cover) and oil from under the distributer. I took the car out yesterday and it’s still leaking, that was after replacing the PCV and cleaning out the oil valve cover breather. I would really hate to have to take the car to someone to correct; I need to keep trying on my own.
Sicksatellite, if your reading this where can I find a PVC like the one you showed in your posting?
