...how do I remove this?

[Petrograde]

OK,.. another project I'm working on. Does anybody know how to remove the PCV tube and ring from the upper intake? I've twisted and pulled on it,.. to no avail.

Sorry, Petro, all I can think of is smart aleck answers tonight.

What does the underside look like, can you see it. Is there threads or is it smooth. I would say if it is smooth it is probably pressed in and if so. KEEEEEEEP PULLLLLLLLLLLLLLING.:P

Tom, I ran into the same predicament when I had my intake powdercoated.
I did NOT risk breaking something, so I gave up on pulling it out and just removed the short rubber tube from the metal fitting.
I then covered the metal fitting with masking tape so that the powdercoater wouldn't wreck the fitting when he sand blasted the manifold while prepping it for the powdercoat.
When I got the manifold back, I spray painted the fitting with Gloss Black engine paint.
It looked like the fitting is press fit into the aluminum manifold....

I agree, but since I had my manifold done in black thermal dispersant coating I didn't mask it.

The shop manual is not very helpful at this point. On page 303-08-10, it describes:
Postive Crankcase Ventilation (PCV) Valve

Removal and Installation

NOTE: 4.6L (2V) shown; 4.6L (4V) similar.

It goes on to say that you just "remove" the PCV valve (for the 2-valve engine). Not very helpful.

Going to guess here, but would an application of heat be helpful. Not a torch but putting the manifold in the oven and apply 350 degree for a period of time say, 30 minutes? You can add a few canned bisquits and have breakfast at the same time.

One thing...
That's NOT the PCV Valve...

thanks guys,... :up:

It does look like it pressed in there, I guess I'll just mask it off.

did anyone who has powdercoated or jet coated their intakes mask off the inside or the top of the lower intake? just curious...

No, As a matter of fact, my powdercoated recommended that we powdercoat the underside of the upper intake (lid) to give it a smoother, glossy surface....
kinda like a 'poor man's' extrude hone. It turned out really nice! We did NOT powdercoat the upper intake's machined gasket surface.

(I would mask off the lower intake manifold's machined gasket surface and internal ports/passages.)

yup,.. that's what I was thinking about. Thanks for confirming my suspicions.

I've done a half assed polish on the outside (just to smooth out the rough casting) no waay I'm gonna start grinding on the inside! :eek:

I can't wait to get this done! It's still gonna be a couple weeks before I can send them out for coating, but I've been trying to get this done for almost 2 years! .....finally! :burnout:

[Joe Walsh]

Actually, I think that your polish work looks pretty good...
I completely de-burred and 'dremelled' the sharp casting edges off of my intake manifold, but I did not polish the upper lid like you've done.

My coater did not do the inside. I believe he did mask the gasket surfaces and hose flanges, not sure if he masked the entire bottom or not. But I did grind and polish on the inside pretty thoroughly, mostly to blend into the enlarged throttle body ports but also to take off any sharp edges, bends, and protrusions inside.

MENINBLK ... What is the correct name for the part in question? I see no textual references to it in the shop manual -- plenty of pictures in the engine section, though.

I am guessing it was not intended to be removed. Is that your thought also?

[Joe Walsh]

They run coolant through that fitting (the two small tubes) to heat it up...or maybe to cool it down....:dunno:
I believe that the fitting is designed to pre-heat/or cool the crankcase fumes as they enter the intake manifold.

[torinodan]

it's my understanding, that thing is used to heat the crankcase air so oil residue dosn't sludge up in the intake and take away from the operation of the PVC valve. like always i'm open to any corrections.

[Warpath]

It makes sense. I don't know for sure though. If it warmed up crankcase vapors, it would prevent the oil vapor from condensing when it cooled. I'm not sure whether crankcase vapor is that much warmer than intake temp. If it were EGR, the intent would be to cool it.

Yes, you are right, however it does put oil residue on the inside and that same residue hits our spark and gets burned up during combustion.

Some folks feel that this slows the spark process and gets the underside of
the intake dirty. I agree - the inside of mine was dirty when I took it off.

I installed a Steeda Oil Seperator (made for 03/04Cobra) in the middle of that line and solved the problem. It fills up evey 300 miles or so unless I push the speed - then faster.
Dennis Reinhart can get them for you and he has the specific instructions for installing it on our MM firewall and what the extra needs are.
Enjoy.

Wish i could help better but Dennis did mine .if ya wanna ask him.. :D

The Steeda unit is just a small oil/water seperator which are used for air compressors and the like with some tubing and fittings. You could go to Home Depot or Lowes and pick the parts up for cheaper. I think Steeda sells them for like $65. You just put the seperator in series between the PCV valve and the intake hat.

[torinodan]

Did someone say Home Depot? Cool, now I have other mod parts to shop for.:P
