Currently doing vanos seals, have a couple questions.

Just got into changing my vanos seals and valve cover gasket while I am at it. So far I got the cover off but I accidently broke off the tubing for the part that plugs into the top of the valve cover in the front pictured below.

Does this whole assembly have a part? Or do I have to replace the entire hose running into it?

Also, I cannot seem to get the clip out of the bottom left solenoid on the vanos. It is stuck and I have been yanking on that thing like crazy trying to get it out to no luck. I don't want to break it, but eventually I am going to have to attack it with pliers or something else. Anyone have any tricks to getting a stuck one off?

You can replace the CCV hose separately, but you may want to consider replacing the entire unit and hoses.

Keep trying at that plug. Mine was jammed too. Use gloves.

I was able to get it out by pressing down on the metal pin thing and lightly prying it with a screw driver. Got the vanos out now. Going to be taking it apart.

As for the CCV, I probably should just replace it now then, but I haven't read anything about it though so not sure how difficult of a job it would be yet. Going to do some reading once this vanos gets done.

Thanks!

I just did my vanos reseal, valve cover gasket, complete CCV replacementl, plugs, new intake piping and expansion tank in 4 hours. It's not as bad of a job as everyone says it is. If I went off the quoted times to do everything I would have had 12hr into the whole job. Just break the old CCV lines or cut them to get them out mount the new stuff lube the o rings and hold/pry the new piece on. Just look at it before install and make sure you know how it goes together.

Oh also installed a new fuel pump at the same time.

Within the past month, I have done the following:
- Intake boots
- Plugs
- Fuel pump
- Fuel filter
- Disa valve clean + o'ring
Today
- Valve cover gasket
- Vanos seals

I broke off that top part of one of the CCV pipes and am looking for a quick fix that will hold until I get the parts in. I am just going to replace everything with the CCV stuff because this pipe breaking from dry rotting is a sign it all must be dry rotted.

"because this pipe breaking from dry rotting is a sign it all must be dry rotted." You nailed it. Get the CCV system (CCV Valve, and the hoses) replaced!

I did my CCV and oil filter housing gasket today. It wasn't a quick job... Lol

Some high-temperature tape would provide a temporary fix.

The part you broke is an oil return line, however it barely ever gets used. I broke the exact same part while working on my vanos seals. I tape it up and drove that way for a couple of days, checking it each day until I got the replacement part.

When you decide to do it right, consider removing the alternator to access the CCV system. In my opinion, it's less work and risk than dealing with the fuel rail to remove the manifold.

That is good point doing oil filter gasket and ccv valve at same time. replacing pulleys and cooling system.

And this is why I'm going my CCV, VCG, VANOS, and OHFG in one go next weekend. No reason to do the same removal 4 different times for parts that inevitably fail.

It's a crankcase vent tube, not an oil line. Crankcase oil vapors flow out of the valve cover into the oil separator, where the oil is removed and returns through the dipstick tube and the air flows into the intake manifold.
