Bad pcv?

[Stroked10]

Hey guys on my 82 c10 383 stroker. I found oil on the intake manifold valley below the carb, cleaned it up next day it got wet on the same spot, seems to be coming from the intake bolts. I also found the dipstick pushed out. I have an oil leak from the front of the engine maybe front seal or timing cover. Could all this be caused by a bad pcv not venting the pressure properly?

The setup I have is pcv on the drivers valve cover with a vaccum hose connected to a nipple on the bottom of the carb and a fill vent oil cap on the pass side valve cover. Thanks in advance.

Could be, but the middle 4 intake bolts seeping oil up is pretty common we always use high temp silicone on the threads. Maybe replace the pcv valve and blow out the line. Remove that valve cover and see if it has a clogged valley and than check the breather on the other side? If i recall there was a discussion on this a while back and a way to test it. Good Luck

Thanks for the reply!. It is the middle two on the drivers side. I'm gonna rtv the threads. Do you know what type of pcv valve I might need? Stock 350 one?

Take the pcv off and shake it in your hand if it makes a rattling sound it good no sound replace it.

Rarely does a pcv go bad. If your dipstick is blowing out then your ring seal is shot. Pcv is supposed to burn the vapors from the crankcase to prevent it venting into the atmosphere. Nothing else. Simply an EPA buttplug

PVC valves DO go bad, they get clogged up, gummed up and can stick open or closed.
That is why they have a replacement interval just like engine oil or spark plugs do. Check the maintenance schedule in your owners manual.

Should the OP start tearing the motor apart now? You seem positive the ring seal is shot. Only thing that could cause dipstick to blow out?

While I do agree with this
"Pcv is supposed to burn the vapors from the crankcase to prevent it venting into the atmosphere"

It's your next comment
"Nothing else"

Where you seem once again misinformed.
Actually the PVC Valve does a lot of other stuff.

The PVC works to extend oil life (as well as engine life) by removing Moisture (water) from the engine oil caused by condensation in the crankcase.

Examples of other benefits of a properly functioning PVC System would be lower fuel usage and lower emissions.
As to your last comment,
The term "buttplug" does seem fitting in this case..

That all folks..............

Lol.. I changed it, so far no pushed out dipstick, drove it all day yesterday. I still got a leak from somewhere in the front, one of the disadvantages of having the sway bar sitting 3 inches from the floor is that I cant get down there and look .. Need a new jack, thanks for the help guys!!
