Will start working on replacing the PCV hose tomorrow on my 04 ZX3 2.3L. Could not find the hose at local auto parts, will check out Rock Auto like someone mentioned and visit Harbor Freight for some long 1/4" drive extentions to remove the hidden manifold bolt.

Thanks for the thread & additional information.

Question:

Is this a quick disconnect hose going into the intake manifold?

Don't want to break it removing it.

Thanks!

Good luck with that one, ive yet to see that one out.

I was told its easy but i couldnt get mine out. I wound up cutting the line and sliding it off the tree nipple part the line slips over and just leaving it on my intake.

I did see red triangle clips people said to push in on but mine never would come out. It has to be one of the more stupid designs of clips on the car.

I took off the whole intake and couldnt get past that sucker.






Triangle tabs they say you can push on to get it to come out but i couldnt get anything on it to push em in to even unclip it. The triangle things are at like 3:00 and 6:00 on oposite sides of each other.

Just got the hose off by pressing down on both sides of the red collar while pulling the black hose out.

Thanks!

Could not find the PCV hose except at the local Ford dealer. Went ahead and ordered one to arrive in the morning for $44.

On motorcycles, normally pick up a auto heater hose close to the same bends and ID (about 30% the cost) of the motorcycle radiator hose and cut to fit. Probably should have done this on the PCV hose, but bit the bullet and bought it from Ford.

Many small airplanes vent to atmosphere. Some have an oil separator to let oil blown out of the crankcase vent return to the crankcase. Not knowing much about emissions systems, decided to install the original style PCV hose. Like previously mentioned in the thread, thought about capping the intake manifold where the PCV hose is connected and venting the crankcase to atmosphere, but not sure if this modification would cause the ZX3 to fail the NC emissions test.

Do they sniff around the car under the engine and stuff? I do smell mine so it must be venting quite a bit but im kinda looking for any smell that seems different incase there is a problem.

I don't think so.

Guess I am being too cautious and worry about tripping an OBD code or their computer they plug in during the inspection.

My other 4 wheel vehicles:
87 Toyota Pickup and 93 Miata, don't have to worry about emission (computer) testing on the pre-96 vehicles in NC.

Just got back from Harbor Freight with some tools, getting back on the ZX3 project!

Here is the red clip removed, back in the fitting, and end of the black tube that fits in the red clip or retainer:







Guess this is the EGR tube & it threads right out?



Edit: Got the EGR tube out:
