PCV Elbow?
Hi guys, I have a 98 and I have done a dumb thing.
I was doing some maintenance and while looking for the PCV Valve I pulled on the elbow on the back of the Driver side valve cover and ripped the elbow that connects the port on the cover to the hard tube that runs acrossed the back of the engine.
Well I figured that I could just run to autozone or some place Like that and pick one up.
No such luck. I temporarily put a piece of 7/16" fuel hose there but it doesn't fit as well as I'd like.
Anyone know where I might find one of these, or what the GM Part # is?
Thanks in advance guys, The amount of wisdom here on the forum never ceases to amaze me.

Also, from what I'm seeing, the General made a running change on the pcv hose design (probably mid year) and there appears to be two different hose assemblies for the 98's. It looks to be either a 12558673 or a 12560692, depending on the actual location of the pcv valve itself in the hose (GM calls it a "pipe") assembly. Either way, Im confident it's not cheap.
Call Tom or Bob tomorrow at Fichtner Chev and check with them. They can ease the price somewhat for you (as well as all forum members).
Their number is 1-800-234-5284
Another option would be to e-mail Gene at Karshop (forum vendor) and see if he has anything used. Only problem with used hose assemblies is that the rubber parts of the assembly are more likely to be hardened and brittle from age/heat. Wish I could have been more help.

You would think that something so simple would be easy to find. I'll check the price through the dealer, but with enough looking I'm almost sure I can find a 90 degree elbow that will press on the fittings....
Mine was pretty much rotted from the inside out also.
Thanks for the help guys

I had the same problem with my h/c swap. It's not real pretty but it's under the firewall. I picked up a threaded plastic plumbing adaptor with a PCV size nipple on one end and some heater hose I had lying around. I cut a 1.5" piece of hose, stuck it in the valve cover and threaded the nipple in and it's working fine. I tried threading the nipple into the stock grommet and the fit was to tight and split the grommet. My local GM dealer wanted almost $100 for the assembly.

One thing you can do is switch the assembly to the Z06 setup - works better, is cleaner-looking and the Z06 valley cover is about 50 bucks. The Z06 setup plugs the driver's valve cover hole and the rear tube on the passenger valve cover that the LS1 setup uses. Earlier C5's such as your's need to notch the block in the valley for clearance so a lot of folks won't venture this mod. Later C5's with the LS6 block can skip that step. The front passenger valve cover tube connects the same and the PCV valve is plumbed from the valley cover to the same position on the manifold. Here are a couple of shots of mine.

The piece of fuel hose that I put in there looked like it was bent too far probably kinking the hose. I ended up getting a small 90 degree pipe thread fitting at work and putting it in with two pieces hose about an inch long. Ended up working out ok.
Thanks for all the help guys

OK Patches, now for school! I haven't dissected this engine yet (thank God!), so I'm trying to recognize what I'm seeing in the pictures you posted. On the 3rd and 4th pictures you showed, are the slots/openings in the diagonally sloped wall the air intakes? Does the composite air intake fit in the rest of the valley and feed air into the openings?

The openings are the intake runners in the heads that lead to the intake valves. As you surmised, the composite intake manifold sits above that valley cover. You can see the cam exposed by those two openings in the center at each end of the valley in the third pic. Here's a shot of the cam sprocket and timing chain looking towards the front of the motor.

Thanks. That gives me a much better understanding on how it's assembled. In '85 I had to rebuild an '83 Toyota Tercel engine due to a foolish decision on my part, and this engine is NOTHING like that!
