The Stovebolt Site Forums The Shop Area Engine Shop oil filler tube 57 chevy

ok i got a 57 chevy 235 3100 and it is missing what i would call the oil filler tube. the only engine i have to compare it too is my dad 216 47 3100 engines look similar but i do not have an oil filler tube all i have is a hole where it should be.
please post pics of what the 57 235 oil filler tube should look like or a link to purchase one... i found an oil filler tube at ecklers

but as u can see it says its for small block and then on product illustration it shows its for v8. so not sure if that would be the right one or not.. im leaning towards not the right one. any help would be greatly appreciated. ty

the item you linked goes in the intake of the V8 - there is nothing similar for the 6, the oil is 'filled' into a hole in the valve cover that has a simple cap on it .... you must be seeing the road draft tube opening on your 235, which is in the block just above the oil pan, sometimes called the crankcase ventilator - it's not reproduced that I know of, you'll be looking for used

Are you referring to the draft tube shown here to the left of the fuel pump?

big tonka thats the one im looking for... sorry for the confusion as i said i only had the 216 to compare to soo i guess im sol unless i find a used one somewheres

There's plenty around. Post in the swap meet section - i'm sure you'll find one for a song.

Make sure you're looking for the correct kind though. Does your valve cover not have a oil filling cover? If so, the draft tube you procure will not need to have a removable cap.

yes my valve cover has a filler cap.. so i'll be lookin for that draft tube no removable cap ty for ur help

You could convert to a PCV system...Do a search on here about it if your interested.

an old timer up here said the draft tubes didnt work very well. basically a venturiery affect to creat a vacuum in the crankcase. he said all they did was leak oil. i dont know if he is right or wrong. i was going to convert mine to pcv and i read on here someone used a pipe and installed a pcv on the top. i went one step further and figured out an oil fill tube off a early sixties v-8 intake is the same size. i ordered a chrome one and was going to install the pcv under the breather before the old timer talked me out of it. he said the breather cap is all i needed. anyway i put the tube in and looks great. anyway if you need an original draft tube send me a message i will hook you up.
