Are all the seals (spark plug tube, gasket, bolt grommets) the same on the 1g valve as the 2g?

EDIT: I meant "valve cover". Sorry, me is a retard sometimes.

Yeah as long as it's a SOHC

Curious... why would you want a 1gn?

I believe jonnymopar is installing a metal valve/cam cover from a 1gn onto his 2gn.

This is correct....most people do this because the metal one can be powdercoated whereas the 2gn is platic and cannot be. Also the 1g valve cover has a better placement for the PCV valve which allows less oil into the intake manifold.

Why not buy one of the many metal ones from us magnum people who bought the mancini cover? Unless you got a 1gn already.

1G SOHC has better placement of the PCV line like 2k2patriotblueneon said

Main reason right there. Sure I got it free , but the PCV is the reason I was looking for one in the first place. I've heard horror stories about how many 2gn guys find a pool (literally) of oil in their intake manifold. Just looking underneath the 1g valve cover, not only the location of the PCV tube, but the entire curtain design inside is better. Personally, I sometimes like to take exit ramps like an animal, which is putting all that oil way on the driver's side of the engine... right where the PCV valve is. Not too good. Whether you've got a catch can or not, the valve is still in an undesirable spot.

I've got it all stripped down now. I'm going to do it gloss black with polished lettering and plenty of clear coat over the whole thing. I figured out that I can hide the PCV valve itself right behind my injector cover. If anyone wants pics, I'll put some up.

Please do!! No such thing as too many pics.....especially since we cannot always meet each other face to face and see the cars in person.

Well, I lied. I didn't end up painting it. Hello POWDERCOAT! Sorry about the shitty camera.





Lettering is polished to a mirror finish, black powdercoat, then clear powdercoat. The damn finish on this thing should outlast the car!

Also, for anyone's information, I looked up the gaskets for it and the 1gn gasket IS different than the 2gn. The 1gn gasket has loops that go around where the bolts come through and the 2gn just follows toward the inside of the bolts. Here's what I mean:

2gn:

1gn:

I will definitely have pics of this installed in a few days to show where I'm putting the PCV valve.

Definatley great info
Now get back to us after a month of driving and let us know if there is any oil in your intake...

Finished!




The two pics below are of the valve covers side by side. Notice the curtain design on them is actually very close, but on the 2gn cover (the one with the gasket still in it), the curtain extends all the way to the edge where the PCV valve threads in. Still, oil can sneak right around it if you look closely. On the 1st gen, oil would have to get all the way around it and come back across the top just to get sucked out by the PCV valve.

Now for installation info:

I purchased a gasket set for a 1997 SOHC, which is what this particular valve cover came from. The set comes with 4 new spark plug tube seals, the outer gasket, and 10 bolt seals. The bolt seals are different on the 1gn and the 2gn, but the bolts themselves are absolutely identical. I used my 2gn bolts with the 1gn seals with no issues. Torqued them down to 105 in-lbs per spec (just under 9 ft-lbs). You might have to fight with the spark plug tube seals a little bit. Just get something round and flat-ended and really push them in. I used a suicide knob off an old John Deere tractor and it worked great. (What do you mean you don't have one of those?? )

I actually used quite a few pieces from the existing PCV system. The small plastic hose that originally went from the PCV valve directly to the intake mainfold is what I used for the rear hose. If you look in the engine pic above, the contour of that hose directs it right in front of the coolant reservoir so friggin perfectly it looks like it could be stock! Connect that plastic hose to the right angle input on the back of the valve cover with a piece of 3/8" hose and you're golden.

Take the right angle adapter off the back of the 2gn cover and use it for the outlet near the coil pack on the 1gn cover. I was able to direct another piece of 3/8" hose directly down to the PCV valve that way. The PCV valve, which is just a stock 1gn spec, is attached to the intake manifold using the same straight-through coupling that was already there. Perfect fit and its almost out of sight. All you really need to make is a 3/8" to 1/2" adapter to connect the other end of the PCV valve to the hose coming down from the top.

And for the hell of it, if you have a CAI, re-route the throttle cable underneath the intake manifold for style points.

coool

hey i got a powder coat red mancini cover on my neon and i was curious because i started noticed some oil around the spark plugs soon after the installation, wtf should i do?

Pull your plug wires off and double-check the tube seals. You might even want to take something thin, but blunt-ended, and kinda poke each seal down a little bit to make sure they're definitely around the tube itself rather than resting on the top of the tube. Don't use anything sharp though.

Post resurrect just because someone happened to ask me about it.

I've been running this setup for over 50k miles and the intake is DRY. It works perfect and looks much better. Do it.

hmmm.... my sister has one of these sitting the garage. I wonder how much she'd let it go for. Right now, I just have a breather on the tube that comes out of the vc, not too sure what it is, but thats what I was told to do with it.

If you've got all the stock 2gn PCV hoses, I can help you put it on, depending on if she'll give it to you.

There are two "ports" on the VC. One on the back that originally goes to the air box and one on the side that goes to the intake manifold. Which do you have the filter on?

Its on the rear "port". When I removed my airbox, instead of using the hose they give you, I was told to just put a breather filter on it.

Same thing. Either way, you're drawing in air through some type of filter. Did you cap off the nipple on the intake that you didn't use? If not, you're drawing unfiltered air through it.

BUMP is it normal for the pcv to make a "chirping" noise? I notice when it makes this noise, that i can feel the valve shaking like the ball thing inside is moving back and fourth rapidly....

I would say "that ain't right". Mine is silent. Maybe time for a new one.

I got a new one, d-railed suggested there isnt enough space between the pcv and the inlet on the intake manifold. Currently, there is no hose between the two, i will try moving it up top on the valve cover and see what happens

IDK if the distance from the IM would matter. I know it is an old school PVC, correct? I have the 2gn one mounted directly to the IM for all intensive purposes, and it seems OK.

There may be other issues if there are pulsations in the IM. Either there is a lot of reversion going on, or there could be a valve not sealing 100%. I would put a vacuum gauge on it to see if the needle is bouncing at idle. It should be steady. Even on the older cars I have owned, I have never really had a PVC valve vibrate, or make any sounds, other than air sucking through.

moving it up by the fuel rail seemed to help, HOWEVER.... I was using some soft rubber hose from home depot, and the hose AFTER the pcv valve would flatten out when the car was running at idle. with throttle it would pop back up some but not all the way. wierd

The soft hose was between the valve and the IM?

It would naturally collapse from the vacuum. If it was between the valve and the VC, then the outlet in the VC may be partially clogged, or the baffling in there is gunked up. You need a fairly rigid hose either way.

^noted and fixed. Thanks for all the help Bill!

That's what mine has always done. You're right, it's like a faint chirping noise at idle. I've never had a problem and I still don't have a drop of oil in my intake. Everything is still set up exactly as it is in the pictures above.

Interesting, none of the 2.2's I owned did that. It is the same PCV valve AFAIK. The daughter's 1gn SOHC does not do it either, and my DOHC currently has no PCV system due to the PO's lack of intelligence. So until I get something plumbed, I can't say much there.
