Total bullshit. They need to make things right. That's unacceptable. I'd find another way. Hell, coat a stock one with red Glyptal. Done. I mean seriously.
I agree. He still needs a pcv. After he addresses the blowby problem.
Why couldn't you? I've also heard that about not running the evac with mufflers. I hear Pam Anderson was a virgin, too.

That was my thought, also. You'd think the car would be a real turd, with that much loss of ring seal. Need more details or testing...
Someone has been on the kat litter early this morning. lol
Is it not what hot rodding all about?

I posted that on FCBO about 10 years ago. You know what I discovered, they have no less than 10 "Dan the Man's". Big Block Intake Manifold Insulation Plymouth Dodge Mopar
You can use pan evac’s with mufflers.
I grew up in a very backwards city. And state. I have forgotten the exact year it was but something where in the early 1970’s the city passed “noise” ordinances that were (and still are) at best draconian.
Bracket cars were mandated mufflers. At first, it was hit and missed enforced. By the time I started racing there in 1980 every bracket car had mufflers. Period. When they had fuel or alcohol cars running and class racing they didn’t need mufflers and the track made money. IIRC it was 1984 or 1985 when the last fuel Funny Car made the last pass down the nicest, best track in the region.
I have been, and everyone who raced at that track and others in the region now at most tracks who wanted header evacuation did it with mufflers.
There is one well known muffler company everyone knows who will tell you if you use their mufflers and pan evacs it does nothing even though I had customers successfully using their mufflers and pan evacs.
It can be done. I’ve done it for years. I still do it on my street/strip car.
I will say this. There may be, and probably is a muffler or mufflers that for whatever reason will stop the function of pan evacs. I would say if you find this issue just change the mufflers.
In fact, I run mufflers on my engine dyno. Many engines run pan evacs and they work through the dyno muffs.
I just bought a pressure/vacuum sensor for the dyno so I can measure crankcase vacuum or pressure (hopefully not pressure because that will suck no pun intended) so I can quantify how much vacuum the PCV and the pan evac can pull (or not) and low load high vacuum scenarios and how well the pan evacs do at WOT power pulls.
I promised ME Wagner I would test their PCV valve in a closed system like I do it with pan evacs and share my results with them. They were concerned or maybe not concerned but they are certainly curious about the results.
Say what? Do NOT tell me she’s not as pure as the wind driven snow. That will hurt my feelings.

I take it the retainer is the piece bolted under the front wall.
Seen retainer on a few engines in pics, never in person, definitely didn't know the purpose.

Well, after looking at evac systems, I see where I got the idea, can not use with mufflers. It's at the end of every one of the specifications! Maybe it has something to do with a high back pressure mufflers. Okay, now I have choices.
Thank you.
Thank you.
I’ve got a customer engine on the pump. Should be done by Friday. So Monday I should have my junk on there and getting my initial break in stuff done and then I’ll post some results of crankcase vacuum/pressure testing.

Intake Manifold Silencer Insulation Kit.
.........Its purpose was listed in parts catalogs as "Valve Tappet Noise Reduction Silencer Package." Some say its real purpose was to prevent the intake manifold from cracking due to heat. Some say it was only used on air conditioning cars..........Big Block Intake Manifold Insulation Plymouth Dodge Mopar
I believe the pad could help control some of the stock pan flex and crossover heat.
Then too there's the old school approach..............
But I think the sheet metal pan is the better choice over a stock pan for flex.
I ran evac tubes on my fenderwell headers. 67 440 with tunnel ram with Dynomax mufflers. Street/Strip car. Never had an issue with this concern of OP's. Didn't run a PCV either. Im currently building a 383 thats going to be similarly built in a valiant. I'll be using an Edelbrock RPM, 750 dp, fenderwell headers and Dynomax mufflers with turn downs. Street and track driven.
