Even the Integra has some German engineering, PCV valve broke!

Every try to replace the PCV valve in a 94-95 non-VTEC Integra (RS/LS)? It's IMPOSSIBLE!!!!!!!

Normally, you're supposed to be able to just pull it out (it's located behind the valve cover, between fuel injectors #2 and 3), but NOPE, not here!

It would spin around, but if you try to pull it up it will not budge. After like 300 pounds of force, the PCV valve breaks!!!!!! WTF?

You wouldn't expect Honda to put a round peg in a square hole, but that's exactly how this shit was designed (the grommet/gasket it goes inside is square in shape)

So various pieces of the valve come flying out, like a spring, a metal valve thing, and plastic pieces, but wait, the base of the valve is still in the tube! This broken valve WILL NOT come out no matter WHAT!

At this point, I just tried to install the new valve on top of the remains of the old one, but it won't quite go in.

I mean, you kind of expect this shit in a European car, and of course it's possible in an American car that uses the plastic elbow PCV design, but it should NEVER happen in a Honda!

Hopefully the 96+ Integra doesn't have this problem, nor do GSR's of any year; these cars have their PCV valves on the valve cover, so even if it does get stuck, you can just take off the valve cover and push or pull it out from the other side.

Yeah it was easy on my swapped B18B 94 LS and original B18B1 96 Integra RS . HOWEVER, thats the only easy engine. I think the GSR (B18C1) is just as hard as your earlier B18B1, considering it has an entirely different intake and the PCV is actually located below intake runners.

The "easy" late B18B/B18B1 :

I've seen a number of PCV valves break just like this. There should be a rubber gasket, plenty of times, because they often get installed dry and then they dry rot into place, they will break the second you go to remove it.

Hate to say it, but you might need to pull the head off in order to remove it completely, otherwise you do risk having bits of plastic floating around the motor by the valves, which will possibly cause you way more trouble than just pulling the head off. Your alternate option is to use the same method used when removing a broken bolt from the block. Or, intentionally break it, preferably in the largest possible pieces so that they don't get lost in the sauce. If you've never done the head gasket, now is as good a time as any, because you're going to want to push the valve out the top of the head, not down into the block where it will be damn near impossible to extract, and be a big time bomb.

My Neon has a screw in type valve, and the magnum is a push in type like what you're describing. Just take some oil from the dip stick and get the rubber gaskets oiled before you put the PCV valve in. Should prevent future problems.

From something I found in a forum search after making that post, I'm going back into the old broken valve tomorrow with a screwdriver and hammer and just break the remaining pieces apart (it's dark now, so I'll do it tomorrow).

Oh YES I'm coating it with some oil!!!!!

This PCV valve isn't on the valve cover, but rather in a separate box thing behind it (the 96+ versions have it in the valve cover, but not this 94)

I'm going to intentionally break it tomorrow (it's dark out now).

If you can still see it too, dogisbadob, spray some light oil or something around the base of the valve (the gromet). Let it soak overnight. Otherwise yeah, JGrabowMSt is right about stuff falling into the intake. AT worst, you might have to take off the intake, but not necessarily the head.

Is that the intake manifold? I'm not too familiar with pre 2000's Hondas. I'd pull that off to do the removal. It's overkill, but far safer. Since it's not the head, it means you shouldn't have too much complicating the job either. Bits will fall straight into the intake, so my suggestion is to take a drill bit and drill into it, and see if you can slowly pull it upwards with the whole drill for leverage. Try wiggling back and forth and see if it helps any.
