Question Crankcase ventilation question

Well, I've got the motor in the 53 down right now and I noticed that the PCV valve seems to be sucking a little oil. The car doesn't visibly smoke but I can see a witness mark in the intake where a slight amount of oil has been mixing with the gas just below where the PCV port on the carb. dumps into the manifold.

I've got tall valve covers with what appears to be adequate baffles. The pcv is nice and wet and so is the inside of the hose. I've been running a K&N crancase filter in the other cover. I like the PCV system but I can live without this kind of thing happening. I would like to go to some sort of a bolt on PCV "stack" to get it up and away from the oil. Is there anything out there for a problem like this?

Thanks, Charlie

A little oil mist is to be expected since the valve train aerates the oil no matter what you do, check out my pcv system. It works much better since it is out of the highly agitated valve cover area and seems not to pick up as much oil as the factory system does. I have a coarse stainless screen below the pcv valve that seems to condense the oil before it hits the valve also.

Not a new idea mind you.

Chuck - I like the looks of that idea especially the coil and the clear hose thing - it allows you to see what's actually going on in there. So you just drilled the manifold in a place where there is little activity as possible, huh? I didn't see a grommet. You must have just made it a mild interferance fit with the PCV - am I right?

Originally, when I built my motor, I went with a light giggle pin in my PCV because of the low vacuum caused from way more then stock valve overlap. Is this screwing up? If so, what number PCV would you go with.

I musta just fell off the shrimp boat because I've never seen a set up like this - but then I guess I never looked real hard.. The stock valve cover thing has always worked for me but after seeing a little burnt oil on top of my pistons and yellow "skidmarks" in my manifold <chuckle>.. I figured this ain't workin'.

Anyway, Thanks for the advice. I'm definatly gonna go with the idea. Can you give me an idea precisly where to drill the hole?

Standing by...

I drilled a 9/16" (or was it 5/8"?) hole and just siliconed the thing in, I drilled a 1/2" hole through but stopped short with the 9/16" hole so there would be a ledge to hold the screen in place. I choose a position far back on the manifold near the rail in a location where the intake/exhaust crossover ports don't pass. Since the motor was just rebuilt there is no blowby to speak of so the valve stays really clean, a worn motor might not be able to use the loop in the clear line since it might get oil logged. Hard to say since this is the first time I have tried this.

I've never seen this type of setup either but I wanted something different and I hate valve covers with holes and hoses in them, if you check my profile you can see other photos in the album of the setup. I would like to plug the breather but I had already painted them so...I may machine an aluminum fill cap to replace the breather since fresh air is brought in from the other cover through silicone tubing. Ideally I would like to get another valve cover with a nipple and connect the two so fresh filtered air would flow in from both valve covers to the pcv. It works fine the way it is for now.

The pcv I installed was a model I picked off the shelf just because it had the right nipple size and was a standard inch diameter, it didn't seem to affect the engine any. I think the pcv valve was for a Chevy actually.

Give it a try?

I use a system similar to Chuck's on my hemi. A little easier to do there since it has a separate valley cover under the intake manifold. I drilled a hole the rear of my 1/4" aluminum valley cover, installed a 1/2" electrical conduit/panel adator fitting stuffed with some of that coarse stainless steel kitchen scrub pad, and ran a PCV valve/hose from there to one of the intake runners. I have air inlets in both valve covers thru Moon competition vents. I took my clue for this system from the hemi's original valley cover that had a road tube in that position.

Chuck, yeah YOU BET I'll give it a try. Thanks.

My motor is fresh too, a little over 3k miles since I built it. The real reason why I tore it down this quick was to have a look at the lifters and pistons. (Those Jurassic springs scare me to death, puttin' the squeeze on a new bumpstick..) Once I got into it, I found that the PCV had been fouling up the top end - you'd never know it by just looking at the plugs.. They were a nice grayish white.

For now, I'm shelving my old stock, hot rod heads. I wimped out and got a set of WP Tourqer II's for cruising - something I said I'd NEVER do. I think my top end will stay clean now with a custom CC&W (that's Chuck Charlie and Willys) PCV system. Before I drill the intake, I'm gonna look at the idea of building a low profile mini ventilator box with a NPT nipple that threads into the manifold, similar to what Willys talked about, and stuff it with some of that honeycomb breather material. The top side might have a grommet that will accept the valve like in the stock location.

Willys, I like the looks of the Moon cover vents too. I'm wondering, how well they are baffled.(they probably don't relly need to be, since they sit up so hi) I'd just LOVE to get rid of the stock internal baffles in these covers - I think one of them has been kissing a rocker occasionally, and it takes a month of Sundays to get the oil back in my motor after an oil change. I can drink beer faster than those covers'll take oil..

I'm headed up to the Wheel Shoppe tommorow night, to see if Roger has a set of Moon breathers in stock that he's not TOO proud of. My Tourqers are supposed to be here tommorow too.

This weekend here was like August and time's a wastin'.. Yard work's all caught up - I'll be ready to rock and roll, REAL SOON!

I did say it was not a new idea, just never seen one before. Thanks for the photo Duke, I do love any photo of a 6 pack 427 Ford...

HooooAhhhh! <img src="graemlins/drool.gif" border="0" alt="[drool]" />

After looking over the 427 OEM PCV oil separator and talking to a few more people, I think I've come up with a pefect, REAL cheap, solution to my problem here. It utilizes much of what all of you suggested and it's in a small, sanitary looking, package.

It's a Wix #42993 Breather. $4.30

I know clutter on the valve covers isn't the best thing in the world but this deal really doesn't look all that bad. It's a satin black round filter canister about 2-1/2" tall and 2- 1/2" wide. It has a filter element inside, made out of stuff similar to what Willys was talking about. The PCV presses down inside the angled hole W/grommet ontop, allowing it to sit plumb with the world instead of leaning at the angle of the top of the valve cover. That'll help the jiggle pin center up better under throttle conditions. It gets the PCV valve up and out of the action too.

I'm gonna go with the clear hose to see how well it works for a while. I'm also gonna go with different crancase filters too. Preferably Moon.

Thanks all

The ones I use (see the "Close up of my hemi" photo in my photo album) had a urethane foam rubber block in them. I converted the one on the drivers side to oil filler/vent service by screwing a metal spring on the bottom of the cap so it pulls off and on easily. In that one, I put in the kitchen scrubber stainless stuff 'cause I was tearing up the foam rubber when I removed it to put in some oil.

Ditto with chuck on seeing ANYTHING to do with an FE engine. I'm not a Ford man by any streach but that is a fascinating machine.

Willys, nice looking stuff. That inline motor in that chassis in your photos - is it a 292? Nice package. something like that would look good in a 53 retro rod.

No, actually that is a 'built' 230! Gets over 25mpg and if I'm not careful, my son beats my Willys off the line @ a stop light. I divided the siameze intake ports in the head and cast an aluminum 180deg, 6 equal length runner 4bbl manifold. Unbelieveable torque for a small straight 6.

Wait 'til I post some pictures of the 235 6 that I am building for my '53 pickup.

I've been a 235 buff practically all my life. Sometimes I regret yanking the one out of my 53 but I just couldn't put up with that leaky cast iron powerglide for another minute! Once I dove into it, well... one thing led to another and I wound up with what I've got now..

I've still got a 58 235 core motor out in the shop with a fresh hard seat head. It'll go away cheap I reckon.

I am running a 200R4 OD tranny using a Stovebolt Engine Co. adaptor. Therefore I won't have to deal with a leaking PG -- I'll have a leaking 200R4!
