'71 Mustang clicking issue
(Yesterday, 07:31 AM)73pony Wrote: Either way works. The inlet side just needs filtered air in. The PCV valve on the other side connects to a vac source.

You mean the one on the driver side is a vacuum source and the one on the passenger side is fresh air correct?

Yes. The passenger side is a fresh "filtered" air intake and on the drivers side there should be a PCV valve (has a ball in it) that needs to connect to a vacuum source. The ball actuates up and down (basically open and close) to allow the vacuum to suck air out of the crank case and allow fresh air to enter the other side to maintain a specific pressure on the crankcase. This helps prevent pressure getting to high in the crankcase and creating issues like blow by. This is my understanding of how and why the system works.
'73 Grandé H Code. Headman long tube headers, T-5 Transmission, 3.70 Traclok, Lowered 1" all around, soon to have Aussie 2v heads w/ 2.19 intake, 1.71 exhaust, screw in studs, full roller cam 608/612 lift 280/281 duration LSA 112, 750 CFM double pumper, Holley Street Dominator intake. Still a work in progress.

'73 F code convertible. Bright red. Needs total restore.

 Yes, that is it in a nut shell. The inlet side also allows hydrocarbons to vent from the crankcase when not under pressure. BUT what most people don't know or realize is that the WRONG PCV can damage your engine by not allowing the correct balancing of pressure. You can't just put a PVC in the hole because it fits and hope it works!!

Does it matter which side the PCV resides?  I ask because mine is on the passenger side, with a cool Edelbrock breather on the driver side.  No biggie to change if necessary, just curious.

Doesn't matter. Stock set up was PCV on drivers side.

 True, the factory side is on the left for the PCV which runs to the base of the carb, back or front depending on the carb you're using. The reason for the tube on the right going to the air cleaner was so that any hydrocarbons lingering in the crankcase, will be drawn into the engine and not released into the atmosphere. Don't forget, we were all getting 'worried' about pollution in the air............ and where has that  got us!

Hahahaha I doubt emissions are not on anyone's mind around these parts. Well I got quite a few things ordered. Only thing left is a harmonic balancer. And still waiting for the Marti report. As soon as I know I will post the results so we can finally find out what this Frankenstein originally was.

 Well we are all eager to find that out too. Hopefully very soon. All the best,
