thanks Buzz44 it is time for my oil change I will go ahead and just put 6 quart and see if that solves the problem, but I see what you mean 7 quart in a 6 quart system and not upgrading to a bigger pan could be the problem,the only reason I did that is because I knowest that when I was driving on the highway my oil pressure would drop and if I got off the highway as I was slowing down the pressure would go up, so I thought all the oil was on top and none at the pan that's why I added the extra quart but anyways Ill try 6 in my next oil change and see what happens thanks again you are all great

 

5/16" brass rods...where did you put them?

 

If you take off the flute that the rockers go on, there is 4 or 5 bolts that hold it down one of them is thiner that is where oil is feed to the valve train,if you look inside where the threads are your going to see and oil passage that gos in an angle that's where I put the piece of rod I made it to stick out just enough that I can grab it with some pliers but short enough that it does not interfere with the bolt you might have to shave one side to adjust the flow of oil,install the rod put everything back together and start the truck and see if you like how it lubes the the rockers if god you are don if not take all apart and shave the rod until you are happy with the flow of oil, no mes because oil dos not squirt it just flows enough to lubricate that's all hopefully you understand what I just explained

 

OK, I just had visions of those in the drainbacks...forgive my pessimism. I am enjoying one of the benefits of being a pessimist right now, as we are also pleased when we are wrong about something....

This does not help your problem though. The overfill is the next suspect and you are on to that.

Our '66 wagon 390 lived happily with 5 quarts, but that was a car pan, and afaik, the trucks take 6.

 

It seem some pans from cars get put on trucks and they have only a 4qt pans with a total of 5 qts with filter. So the crank may be slinging oil way to much oil up word that causing your problem. Try not over filling it for one thing..

I have a similiar issue - wanting to convert my oil based air filter to a standard air filter. Anyone done that?

 

Blowby and alot of it is my guess. I can't see how else you would get that much oil into the filter housing. Like said before a good way to get an idea is plug off oil fill cap (If vented) and pcv vent so your engine is sealed (I just use my hand) hold it for a few seconds and see how much pressure is created. There shouldn't be any if everything is perfect with ring seal to cylinder. But there usually is and a small amount can be delt with by the pcv system. To much on the other hand blows alot of air through the only way out... The pcv. All this air is obviously going to carry oil with it....

 

Ok I'm going to throw some questions out there. First if you look at the diagram. The PCV is between the drivers side valve cover and the carb.(not air cleaner) then the hose from the air cleaner to the pass. valve cover(creating a loop). If you have pcv's on both sides it creates a flow problems and builds gas preassure in the crank case. Next if you pull the oil cap off while it is running does it have alot of air/steam comming out ? It will have a little air comming out but if there is blow by you might even have oil getting blown out.(I know it is a rebuild but some times the oil rings grt their slots too close together). If that all checks out then I woul go to checking under the valve covers.

 

Did this just start doing this or has it been an on going problem since the rebuilt??
Also do you have stock valve cover or aftermarket. Reason I ask some aftermarket one's don't have the PCV bathel around the pcv valve letting old to be sucked up into it and end up in the air filter.. 5/16 BRASS rods as oil reducers GEEZ seems like a hoking way to do it when you could of just use a Holley carb jet of any size you want to choose to reduce flow..Oh well we all have a way of doing things..orich

 

You should switch out that pump for a stock one, no need for a high volume pump unless you have a oversized oil pan.

 

the extra quart is probably being whipped by the crankshaft and causing foam which is easier to pump than the oil.

 

I have one question, are you running stock valve cover ?

Some after market valve covers the PCV is not shielded and sucks up to much oil that loads up the air filter with oil..

Guys this is an old post,I had to rebuild my engine because of broken oil rings my problem is fixed. sorry for not letting you know sooner.

TASBOJ.......
