The PCV is mounted in the rear of the intake in a aluminum plate and tube. The tube has 2 o-ring grooves cut inside it to seal the valve.
The stainless steel lines tee out from the vacuum port in the center of the intake.
The other line is for the power brake unit.
As Gene said, every piece of this engine has been modified in some way.
The valve covers have a ton of work in them.
They are Blue Thunder aluminum pent-roofs.
I had to cut the ends of the covers off and move them out 1/4" to clear the Dove rocker end stands, then weld them back together and finish them smooth so we could have them chromed. They are highly modified but look like stock steel pent-roofs which is what I was shooting for.
The alternator bracket, distributor hold down,
oil filter adapter mount,
oil thermostat bracket, PCV system, progressive throttle linkage, return style fuel log, even the lower crank pulley are all custom fabricated.
I don't do this for a living, I only build 6 or so engines and 2 or 3 cars a year after work and on weekends. I do it to help pay for the Cobra I am building and to help my friends. And also, more importantly, I do it because I absolutley love it!
