I would like some input on a pcv set up. I have searched the forum on this subject, but wanted some advice on my specific application. This is a 383 sbc. Originally, the truck was huffing smoke out of both valve cover breathers. So I installed a pcv valve on the drivers side and hooked it up to carb. vacuum, as it's suppose to be. On the passengers side I installed a push in style breather. The drivers side seems to be fine, even though I need to look a little more to determine if I'm drawing in any oil into the intake manifold. The breather on the passengers side took care of some of the smoke, but is spewing oil. Not pouring, but enough to be a headache. I know the correct setup it to run a push in breather with hose to bottom side of the air cleaner assembly. Wouldn't that draw oil to the air filter? I have been researching this subject. I'm aware of the catch can solution. I've also been reading about the homeade pcv setup using a compressor filter. Any input? I have included a picture of the set up I have now.
Also, I'm running stock height valve covers because of interference on the drivers side from the alternator. See pic. I wondered if the taller valve covers would make it more difficult for the oil to reach.
I haven't got around to doing the compression check, tending to other issues. And since the motor is strong, I have no desire to rebuild it right now. Let me blow it first.
So I installed the fitting that came with the edelbrock air cleaner, underneath the base. I bought a pcv elbow that was the same diameter and enough hose to connect the 2. Slapped that in the passenger side valve cover. No issues during installation. I was still getting a hair of blowby smoke. I suspect it was coming from the gap between the base and the supplied fitting. I sealed it with silicone. Should take care of any escaping air. I drove it about 20 miles to see if my air filter would fill up with oil. There is a little sign of oil, but not much. To fix this I lined the fitting of the port, on the base of the air cleaner, with some screen. I'm using epoxy to hold in place so it doesn't get sucked in. After it is set and cured, I'll put some still wool in there so the oil has something to cling to. Hopefully this cures it. If not, I have plans for a homeade catch can.
The next time I change the plugs I will get a compression reading. Judging by the blow by and leaks everywhere when I got this truck, I'd say its probably time to be freshened up. It's still strong so I want to drive it. Maybe a good winter project. The valve covers have baffles in them. They are new Edelbrocks. Will the steel wool trick work for the baffles? Any other ideas?
