I have a plug in the draft tube hole with a hose that goes to a pcv valve in the back of my carb in my early 283. When I start it cold no smoke, when I start it warmed up it smokes it didn't do this before I changed the pcv. So I pulled the hose and plug out of the draft tube hole and there's a good amount of oil in it. Is there supposed to oil in there? And the canister is still in there.
Will this help? install pcv on 283 chevy - Search (bing.com) install pcv on ford flathead - Search (bing.com)
Do you have a breather (usually the vented oil fill cap) on the engine? Did you try the PCV valve before installing it? (the "suck" test)?
If it's anything made by GM, then yes. This is the factory corrosion protection package. The draft tube oil blows under the car, rustproofing the K-frame and undercarriage. Cheers, Harv
You say this didn't happen before. So I will assume you recently installed a PVC and removed the draft tube? If that is the case, is the PVC mounted sideways or verticle? Perhaps the valve isn't closing if mounted sideways.
some PCV valves are backwards from some others. there are those that have pipe threads on one end that are intended to thread onto the vac port of the carb and there are some that thread onto the oil fill tube like on a corvette. Did you look at the number on the old one and replace it with the same kind???
Here's another recent thread on the same subject: https://www.jalopyjournal.com/forum/threads/chevy-283-pcv.1316101/
This is true. Now go over to RockAuto. For what ever reason they list Standards V100 for oil fill tube on many applications. ing to say the least.
A buddy has a '67 Chevelle with a 283 that his granddad bought new that has the pcv in the valve cover. So who knows. I got a pcv listed for a '67 283 that is the push in style from Autozone for my 283.
This pcv valve (read vehicle I entered) is an inline and or push in. Grandpa’s car either received a replacement engine or a valve cover swap.
Yes this is still under the intake and I have the pcv valve that screws into the back of the carb. The valve takes a 1/2" hose, so I'm wondering if it has too much vacuum and is pulling oil through.
there were more than one version of the threaded valve, one that screws into the carb and another that was meant to screw into the oil filler tube. the vacuum goes the opposite way and these are valved opposite each other. if you have the wrong one it will use oil. do you still have the old one? clean it and look inside and compare it with the new one
no sir I do not, but he should be able to look inside his new and old valves and see if they are made the same or not (Which way the valve is facing and what side the spring is on)
True, I asked since this topic comes up so often and could help other’s. For myself, I never can get a good number for closed system’s where vapors travel into the treaded end and out the hose end.
I guess a guy could thread a hose nipple to the fitting on the filler tube and another on the threaded part of the PCV and use it inline because you could then turn the valve the correct way
