Can someone take a look at my hose hookups. This is a picture from years ago when I purchased the car, and Ive cleaned it up a lot since then, but this picture is the best I have that shows where I have the pcv connected, and the bowl vent hose (back to the case). I also have the hose that runs from the brake booster to the rear of the intake manifold, and finally the secondaries connected with the main. The main has one other tube that is capped.

Is this right? Want to make sure nothing here is contributing to my white smoke problems.

I spent most of the day working on it today, and changed the oil twice, so that makes 4 times total. I hate throwing away perfectly good oil after only a few minutes.

Every time I run the motor the crankcase fills with at least a couple quarts of gas. I have no idea where its coming from but it MUST be just running down the manifold because #8 keeps hydrolocking.

The floats are adjusted well and shutting properly.

I think I have tried virtually every trick or advice given here and Im just stumped

Car has been sitting in the garage for over 6 months now and it deserves to have someone enjoying it, but

If tomorrow doesnt go better Im calling it quits 


PS

If nothing else at least Im no longer hesitant to work on the six pack, and though Im not saving anything on car insurance, I can pull the whole setup in 15 minutes now.




I should say that Moparjack gave me the idea to remove the center carb and see what comes out of it, and sure enough I set it in a metal tray and fuel comes flooding out the bottom from somewhere in the bore area, but I havent been able to zero in exactly where or why. You can see the gasket above is soaked.

This is with only the fuel pump on, no starting or pumping the throttle or anything. ONLY turning on the fuel pump.

Obviously fuel should not be dumping out, especially a LOT. The float bowl fills, but only up to about the bottom of the sight plug hole where I have it set, and I assume the inlet valve is shutting off when it reaches that level, because it doesnt spill out, but how is it not coming out the open sight hole but pouring through the bores? 

I know Im close. Maybe I just have the wrong gaskets installed?

How do you know? The kit is what it is  

Also, it goes into #8 because the rear of the manifold probably sits nearly an inch lower than the front. Its just flowing downhill, and I noticed it keeps pouring out for at least 5-10 seconds after you shut it off, probably at least a cup, maybe more in just those few seconds


Thanks strawdawg, but I have already checked those sites. In fact I have the wingedwarrior site listed as a favorite and have studied it at least 20 times over the last 6 months, since the problem started. Rebuilt these carbs once, and then replaced the outboards with used, then rebuilt them, and then replaced several of those float bowls, etc etc.

Dont see any cracks, but how can you tell if the power valve is working?

Gotta be something to do with the metering block or gaskets? Idle screws?
