Stumped on oil leak

[squaredeal91]

I just did away with the vent and plumbed this in recently.

I see the fuel pressure regulator there. But how does that affect the PCV valve/vent?

It doesn't. I installed it to keep the factory 3 port mechanical fuel pump from pushing too much fuel into the carb. I have an Edelbrock 1406 which can allow too much gas in if not regulated. When I bought my square, the engine compartment reeked of gas and oil. The top of the engine was wet.
Now it's dry and runs a lot better.

Here's a better picture of what I did. Sorry for the confusion.

Omg @ that fuel filter.

Hey O.P. - we'll send a bill.

Hang on there. If I had money for that I'd have my beast on the road!

I didn't get much done today, it was about 98 outside. I did manage to get it onto the driveway and pressure wash the engine bay/framerails/inner fenders I was careful, so I didn't get anything electronic wet. Then I drove it back around the house and parked it back in its spot. Maybe tomorrow I'll get another test drive done and see what else is leaking.

Ah I see, so it should be routed so that the PCV breather vents back into the carb intake to burn off/use up that oil vapor. I'll see what I can do to simulate that. But that's more of a long-term issue. For now, it's at least working.

This! Is correct.
The engine is made to burn those vapors.

Let's ask @Biz Markie, maybe he can provide insight.

Hate to be a party pooper but while you have solved one problem you've created another. Over time oil fumes from the engine are going to come out of your new breather cap.Oil will collect in the new breather cap and drip on your rocker arm cover and down to the exhaust manifold. Giving that nice clean engine bay a layer of engine oil.
The diagram has that rocker cover being vented to the air breather to recirculate the oil fumes.
When I got my square it had an air breather in the rocker cover. A pretty reddish Moroso one. Over time it started dripping oil. My engine bay was getting oily and smelling like oil more and more. I added the air breather vent hose, fuel pressure regulator and fuel canister and now the engine bay smells and looks a lot less like gassy and oily.

If you move the fuel filter to the bottom end of the steel line,right at the fuel pump,you can run a steel line to 1/4 inch of the carbureator and 1 inch of rubber as a connector. Now a leak at the fuel filter is on the ground instead of on top of the engine.Plus less rubber hose and clamps as failure points on top of the engine.

I had just enough time for another test drive berofe the rain hit today and I think this has got to be coming from the timing cover. Again I probibly only went about a mile or so. So although its not much oil I'd rather not have to deal with this all the time. Oil pan has a Felpro one piece gasket. I guess it could be from the pan on the drivers side. But the passenger side has got to be the Timeing cover no way it could be driping onto the crossmember otherwise (right?).

It was a reasonable temperature outside after the sun went down so I started prep for doing the timeing cover gaskets. Took me a little less than 2 hours. I’ll have to rent a harmonic balancer puller tomorrow.

Hey u know what I like to use?
ESPECIALLY with most fluid seals? Transmission pan gaskets, thermostat housings, intakes, oil pans, differential covers, you name it.
A loooong time ago I fell in love with Permatex brush on gasket sealant. Been using it for AGES and never once did it leak when I was finished. If I was in your position you couldn't keep me from it.
I very liberally apply this stuff on both sides.

I'll get some for the shelf. I've used similar ones in the past with good results for different applications.

Pulled the Harmonic Balancer. Not sure what to think now.

The bottom of the oil pan gasket looks like it was pushed in a little bit in a few different areas. This may have been a contributing factor. Then on the timing cover itself a couple of the bolt holes look stretched/ not flat. Oil could of been coming out of them if there was a gap there. The funny thing is if I had used a cork gasket it would probably have been able to hold that.

So now I guess I'll get a new timing cover? Might as well get another oil pan gasket and if I'm doing the oil pan gasket again I may as well do the oil pump, pickup tube, and intermediate shaft. I didn't have the money for them when I had the engine out of the truck.... Ugh this is getting expensive.

Yeaaaahhh that's a pretty great argument for the pooky.
Speaking of expensive...I think it prolly costed 7 or 8 bucks! COSTED

If you're gonna take it back apart...you could try the old socket trick or getcha a ball peen hammer and flatten on them bolt holes that are givin YOU fits now.
Plus there is little reason to use crappy-assed cork gaskets! That technology has really advanced AND buying better gaskets is way cheaper than new parts, just not fun , youre ish ain't broke -you're not doin it right or it wouldn't leak.
