Valve cover oil leak / smog removal - The 1947 - Present Chevrolet & GMC Truck Message Board Network

79Square · 01-09-2020, 12:26 PM

My alternator went bad on my never-ending newly bought 79 C10 project. When I removed it and took into auto store for testing, the guy asked "when was the last time I changed the oil in my alternator?".... point well taken.

With that said, I realized how bad my oil leak is and that it's coming from front of valve cover. While looking to replace valve cover, and because of all the smog pipes and hoses going everywhere (see pic below), I want to replace it with the basic valve cover.

Looking for help: I want to replace the valve cover and remove smog pipes and put plug bolts in the exhaust manifold. My problem is that I have an integrated cylinder head. Does anyone know where to get a 'non smog' valve cover? What i'm finding with searches are for non integrated only.

Also:
What should be kept? PCV, EGR, etc. (I've already taken out the charcoal canister and the many hoses that go with it)
Will I need to do anything with the carberator? I have a Rochester Varijet II 2BBL.

And any other advice?

Thanks for your help.

If you like your motor, keep the PCV system. It pulls most of the blow by out of the crankcase and keeps your oil cleaner.

Might see if one of these: https://www.summitracing.com/parts/m...make/chevrolet
would fit your smog holes. Or something similar. Would let you use your existing valve cover.

Yes, California type stuff, as well as in the middle of Jimmy Carter years.

Good idea on the plugs. I'll do that if I can't find a normal valve cover for an integrated cylinder head. I was hoping to get rid of those 2 meatloaf pans on top.

Biggest problem is you need to keep that valve cover since it has you throttle cable and tranny kickdown brackets. It's easy enough to get pipe plugs to thread into the manifold, but the holes left in the valve cover, short of welding in plates I don't know. I do not know of anyone that ever did or does make a valve cover for the integrated head 250 six.
