flying oil !!!
Permalink  

i was letting the engine run for awhile to see if my new gauges were working (temp and volts) and i gave her a good rev and oil came flying out of the oil fill tube, and it had the little chrome breater on it. I do have to change the oil, and later on i will see if the level is too high. Also, i now have a pcv valve where the "stink tube" or downdraft tube was. Its also a holley alum. intake and a 4 barrel roch. on it now. Oh, its a 59' 283.  What could make oil fly out like that?? Im fearing for the worse!!

Is there a vent on one of your valve covers? Sounds like you have some serious crankcase pressure there.

He says he has a breather on it.

First off, are you sure the breather works and is clear?

DSC03092.JPGits a brand new breather, and the pcv valve i put in where the downdraft tube was is new and i have it going to a vacum port in the manifold (its just behind the carb, it has three lines, one to the tranny,one to the distributor, and then the one to the downdraft pcv) Its never done this before with the two barrel setup. Also, if i was to open it full throttle while in park, will the back barrels open up? i dont remember?

and yes that is an aluminum intake painted, it just dident want to clean up nice enough for me that day so i gave her some paint.

so i was thinking... i put the intake back on and then did the pcv valve later so i left the little round canister in under the intake that goes to the downdraft tube. it was a little bent so it would fit so i wonder if leaving that in and with the pcv there just to much pressure and thats why it spewed oil at me ???

i was waiting for other to chime cause i'm no expert but with my 283 i ran a short hose off the back of the block to just below the engine, from that same canister you have and i was getting a oil film coming from the fill tube. i ran the hose into the carb on a vacuum line and the truck ran like a turd. since then i've ran a longer garden hose down the frame to just aft of the cab and things are good. bottom line you have to get rid of the crank case pressure somehow

it's been a while since I beat on 283's in my 64. but if I remember if you pull the draught tube out and run a pcv valve to the lower rear port of the carb, you would also change the filler tube to the 307 style with a twist on cap. this would create positive vacuum in the crank case, with a breather cap you would just be moving air. I recall hammering a frost plug in place of the filler tube and using vette covers with an oil filler cap in it. if your using an inline pcv valve make sure it's in the right direction.
just my 2 sense.

Bit of a long shot but would the PCV valve be in backwards? I assume it is in the rubber hose running to that port in the back?

Seems to me the hose sizes are different on each side of the valve, but have to start somewhere...

I was thinking about the idea of closing off the filler tube with a solid cap but then you have no fresh air intake anywhere, do you? Don't you have to have that with PCV?

If I think of the later PCV systems, they have the crankcase air intake vent in the air cleaner, that white banana shaped breather. I assume the oil cap with the "scouring pad" in it serves the same purpose on the earlier systems.

thx guys, im going to put the downdraft tube back on and see what happens. It probally is just too much pressure with the pcv on there. I like what you suggested Steve with the hose running along the frame, that way you dont have the fumes or junk getting all over. thx guys
