Restoring to stock valve cover - The 1947 - Present Chevrolet & GMC Truck Message Board Network

domano 68 · 10-26-2015, 09:50 AM

I am wanting to remove the aluminum valve covers due to poor quality and leaks and replace with stock ones. There is a "pcv-looking" device coming off left side valve cover going into carb. I am wondering what this is called shown here in this picture so I can pick one up and replace. Any ideas? TIA!

Guess - Flame Arrestor?

Just transfer it to your new cover.
It's an air intake to your motor. You need air in to mix with the fumes and be drawn out the other cover with the pcv.

A thought though!!
If you can't get those covers not to leak, you'll have more fun with stock covers.

That's what they called it. I'm not sure where I read it, but probably in the service manual or assembly manual.

Those are nice looking covers, have you tried a good quality gasket set?

I've used these on my last 2 trucks with success..

Fel-Pro VS12869T (rubber with metal insert to prevent over tightening)

For what it is worth, my '70 C-10 SBC 350 has the flame arrestor on the passenger side and the PCV valve on the driver's side; just like shown in your photo.

I like Edelbrock Gasgacinch for sealing these valve cover gaskets - follow their directions exactly - and if you need to remove your valve covers use a heat gun to warm it up first and a nylon pry bar and the cover will peel right off clean as can be...

I vote to keep the aluminum covers as well unless they are warped... the bolt torque is only 3 to 7 foot pounds depending upon whom you believe - so they do need to be straight.

(Wow; that motor is sano! Nice work!)

Off topic so please don't comment in this actual thread to keep it on topic but the leg of my temp harness runs along the frame rail rather than above the driver's side valve cover like your has it - I think mine probably must be wrong judging by the rest of your install :-)

I couldn't find a replacement flame arrestor. I soaked in Evaporust to get back to bare metal. Cleaned up perfect. Classic Heartbeat carries the molded rubber hose.

If you are looking for a molded PCV hose for the RH side. Ecklers carries those pricey...
