Technical PVC Breather system

That definitely p***es the "first glance test". It looks very natural in there. Good job.

 

Thanks
The only vortec intake that looked like there was enough room to drill for tube was the (Summit brand) square bore, it was tight, didn't realize that manifold would over hang the front of the block so far.

 

I got mine shined up and installed. PCV behind the distributer.

Here's a pic of the engine I built for my 36 Chevy former g***er project. I wanted to keep it old school so I went with an Edelbrock C26 intake with the oil fill tube in the front. Corvette valve covers without breathers so I drilled & tapped the back of the intake just in front of the distributor for a screw in PCV valve. This goes into the lifter valley area. Needed a baffle to prevent the PCV from ****ing oil so I made one out of thin steel and screwed it on the underside. (not my picture but exactly how I did it).

 

i put the fill tube in the performer in my 64 as well . painted it orange .no one seemed to notice . much better for adding oil to me !!

 

Just wanted to commend all you guys installing pcv in your rods, jane fonda would be proud of you! LoL

 

Yeah I know I should have gone 100% old school and just let it blow oil smoke out the breather all over my engine so it looks like ****.. Sorry man.

 

I run a PCV valve on all my builds, just to keep the engine bay as free of oil as possible. It's one of the only environmental adds I do. But a PCV valve is good for the engine too, so not just about saving the world.
This image may offend traditionalists, as it contains a PCV, and some OT valve covers on my '39 Chev. You're forewarned!

 

I'm running a post '68 SBC block and an Edelbrock 2X4 bbl air gap manifold with no provision or room for an oil fill tube. The valve covers have 1 hole each, and in normal street use I have a PCV valve in one and a pleated cloth filter breather type cap in the other. If going to the drags where I may turn 6500 or more rpm, I pull the PCV valve, plug the hose and install a 2nd breather cap.
To add oil I have a funnel that fits tight in the rubber grommet where either the PCV or the breather normally goes.

 

Also helps pull moisture and condensation out of the crankcase.

 

And it adds negative crankcase pressure which really helps to keep oil from pushing through gaskets and seals.

 

PCV systems work...period....lots of pluses with no negatives at all.

 

I run a points-type Chevrolet factory distributor/cap with a Pertronix setup in it. No problems in the years I've had it.
The roadster I'm working on will have the same setup. Easy to install and costs around $100.
