CCV Delete "catch can installation"

I don't want to get into a redneck argument over the fact that I bypassed my CCV on a car with a book value of $4700. SO with that said I am going to share what I did and why.

I recently traded my Miata for a 2000 323ci it needed a little love but a good runing car. The Service Engine Soon light was on and after connecting it to the INPA it was showing tell tale failure of the CCV. The car had been sluggish and was leaking oil. The codes indicate lamba sensors on all banks, and misfires. Typical CCV.

The parts and hoses were going to total over $120 and I didn't want to spend 6-8 hours wrestling the stock CCV out of the car and back in. So, I bought an inexpensive catch can off ebay for $16.99 shipped to my door. It came with various fittings etc. I didn't like the way all the CCV deletes I saw looked.. I decided to try and make this look as stock as possible as I do take pride in the appearance of my vehicles.

I decided to leave the CCV in place and just remove the hoses by unclipping them. I connected a peice of 3/4 hose to the breather fitting on the valve cover to the oem 90 degree elbow and reduced it to 3/8 and ran a line to the oil catch can. I did the same thing to the elbow on the intake runner except there I had to block off the bottom side and run a 3/8 hose to the catch can using the port where the vacuum line from the oil dip stick went. I blocked off the dipstick vent tube and made it look tidy.

I started the car and it ran smoother instantly. I cleared the codes and reset all the adaptations. So far no codes after about 10 driving cycles, only about 40 miles. The car picked it's pep back up and I am happy.

Cost Breakdown:

Catch can with accessories- $17.00
1 ft 3/4 hose- $3.00
10ft 3/8 hose- $9.00
Various clamps- $5.00

Total repair cost: $34

Thanks for your input. In case you didn`t know, this has been a topic of discussion around here for some time now, as well as over at the E39 Forum. A lot of people are sick and tired of the problems associated with the stock CVV setup, and are looking for a reasonable alternative. I`m thinking that what you`ve done here fits right into that category.
Please post updates periodically to keep us informed of your progress. Thanks for sharing !

Very nice. This is one of the things that I would like to do whenever CCV will fail.

I am curious as to how much cleaner intake manifold will be after delete. I remember finding a lot of oil on spark plugs and inside intake manifold before replacing the CCV.
There was too much oil on spark plugs, and as a result random misfires would occur.

Edit. Just to make it clear. The car was smoking when bought from previous owner. We were told that insurance totaled the car because mechanic said that head was blown. The mechanic that previous owner took car to had said same thing. Nonetheless, I got a car with smoking issues and were able to fix it by replacing ccv.

Nicely done. Those of us with later vehicles will have to find another location for the catch can due to the presence of the air filter and flow sensor for the secondary air pump.

If those are plastic fittings and a plastic sight tube on the catch can, you may want to consider some means of shielding them from the exhaust manifold heat.

The can will probably need emptying at some point. I plan to check it at oil changes. But I pop the hood everytime I wash the car so I will keep an eye on it.

Hrmm. Well, I didnt take something into consideration, I reduced it down way to far (from 1" to 3/8) this did not allow the valve cover to vent enough and after a week or so of driving it started pushing oil out of every available opening in the valve cover.. it basically blew out the valve cover gasket.. ugg..

So 1" or higher. Good to know before another cover blows.

Mine is necked down from 3/4 to 3/8 on the valve cover side, and 5/8 to 3/8 on the vacuum side. I have no issues. The valve cover is under vacuum, these engines are designed that way. An old, crusty valve cover gasket won't do when you make this mod.

If the OP didn't use a PCV valve somewhere on the vacuum side I could see this as the cause as well.

Perhaps that was it.. I did not use a pcv on the vacuum side.. Either way, I ordered a new VCG and will figure out where I went wrong. Where does the PCV go and facing which direction on the vac line?

I used the oreilley auto parts PCV listed in this thread. This is the guy I copied. I put the PCV in roughly the same place.

SO does the flow from the PVc go to the manifold but not back from the manifold? ALso trying to understand why there would be built up pressure from no pvc..
