PVC Question
I have a 98 with the old type PVC system ( non mod )
The PVC boot is torn and I was researching here on options.
Mostly of the links and photos are now gone, as most post are old.
Can anyone giveme options. Do I have to buy a new boot or has any one relocated the pvc valve. Like installing one with nipples on both ends.
Also I'm not sure how much good it does sitting on it side.
I always thought they had to be installed up right so that they can close when engine not running. I know they are spring loaded but if you takeput then on their side the plunger seems to drop cause it not to completly close.

It sits on its side normally. The heat cable or what looks like a lagre ground strap should remain on there as well as it provides heat to the PCV valve. The usual failure is the connection tube from the PCV valve to the intake. It'll get holes in it as well as collapse.

I don't know what this is.

There should be a large cable type thing. Sort of looks like a grounding cable for electrical. It also supports the PCV valve with a clamp at the end which attaches to the valve itself. I don't have any pictures to show you but I'm sure several people here do, or do a search for it. Its is mostly for heat transfer to assist the PCV valve in warming up quickly by transferring heat from the head to it. Now if you go buy a new PCV valve from a dealer, it'll come with all of the tubes and the valve. Last I saw it, it was like $99 but probably higher now. One of those tubes routes around the rear of the intake manifold from the driver's side valve cover...pita to put in but I did this on my '99 as I found it was decaying back there. I didn't want any oil blow-by spraying all over the rear of the engine.

I'm not sure if yours is identical to mine, but here's the PCV replacement procedure I wrote a while back.

On my 98 the rubber boot that hold the PVC valve tore from the main tube. Dealer could only offer me the whole tube assembly at over a hundred dollers. So I went to a big box hardware store and bought a couple of brass fittings. Modified them a little so a PVC valve would fit snugly in it, and spliced it into the original line. Its a little big (and hokey), but it works. There was no "ground strap" on mine. I remember thinking at the time, that it should have been secured. I taped my up to some other hoses to hold in in place.

The pcv is located half way on the right valve cover,where the number 1 points to and it's in a similar rubber
holder but with no cable attached to it.
It also has a hoses from the back of both valve covers.
I'm understanding that I can't buy just the pcv rubber holder.
I'll need to invent something to hold the original pcv or maybe buy one with 5/16 nipple on both ends and eleminate the rubber holder.
I have very little oil in the intake.
Just a light sheen,no puddles so i'm not really worry about the oil issue that some have. When I bought the car I drove it 900 miles home , it used no oil.

The dealer only sells the entire tube assembly. The normal for your car is a hose going from the driver's side valve cover that wraps around the rear of the intake and connects to the other valve cover, splitting off to the PCV valve which then connects to the intake as shown on lucky's diagram.
