    I put a PCV valve in the valley pan of the DeSoto Hemi in the roadster with bits from Hot Heads Hemi parts. Cheap, easy, and the car no longer smells like crankcase fumes!

    A pelican. It had fishing line around its beak and had been unable to eat. We took it to a seabird rescue place here on Longboat Key. My good deed for the day.

    It seems to run better too. Before I had to keep the choke closed when cold, now it doesn’t stumble and cough until it warms up. Bonus.

    Nice to see people helping animals caught up in our garbage.

    Congrats on the PCV best thing ever for engines.
    Growing up was getting difficult 'til motors were made to stop feeding my lungs with oil fume.
    My childhood was largely in a gas station, on a busy street, with a considerably steep hill.
    The air became sweeter as the older cars went out of service.

    I have a pcv valve on my flathead and my dodge hemi, they are a great addition. Is that hose in the second picture traditional?

    This is where I put the PCV valve in my Mysterion reproduction, in a drilled tapped hole in an intake runner on the underside of the '60s vintage Edelbrock F380 tripower manifold. It is covered by a sheet steel baffle plate. Wanted the engine to run but didn't want a draft tube or PCV valve hanging on the outside. Seems to work ok, for show car anyway.

    This is where I put it on my 331 hemi. I made my own 'racy' valley cover from a piece of 1/4" aluminum. PCV adaptor is a 1/2" rigid conduit bulkhead fitting that fits in a panel hole held by a big jamb nut. It has pipe threads for hose fitting on top to accept the PCV. I stuffed it with some co**** stainless steel 'wool' from a kitchen scruntchie to limit oil blowby, held in with a big cotter key.

    Good call. I put one in my 223 I-6. The draft tube hole is conveniently located under the rear of the intake manifold and the oil cap is on the front of the valve cover so the vapors get nicely ventilated right through the engine.

    I put a short bolt in the hole where the long puke tube bolt screwed in, just stuck a grommet in where the puke tube was & inserted a PVC valve. One run to the parts house & a bolt out of the bolt bucket.

    Best thing I ever did for the 8ba in Rusty (other than the Bubba Chevy distributor conversion)

    In the 60’s when the first used the valve was a screw in usually at the back of the carb. All were serviceable also. I found one for 56 Y-block and put I between the dual quads I am currently using. The tube goes to the valley cover device from a 64 pick-up truck that had to be modified to miss the intake. A V-100 is what’s available today but it is sealed IMG_3656.jpeg IMG_3640.jpeg

    Was the pelican hard to catch Brian ?
    Sometimes animals realize they need help.

    I see your location mentioned as Sarasota Florida.
    Have you abandoned frozen Michigan for good or just while it’s frozen ? :D
    Florida definitely looks like better roadster weather than Michigan at least right now.

    We go back to our home in Michigan in early May and leave the end of October. That gives us the great November, December and January here, and we miss the (increasingly) hot summer in Florida. We absolutely LOVE Sarasota.
    The bird was not thrilled about being picked up and carried, I put a beach towel over its head for the 20 minute drive in the car. I think it was exhausted, dehydrated and malnourished from its ordeal.
