View Full Version : Oil in the plenum normal?

Maybe I'm being paranoid or just being a dumbass, but is this normal?

Just wondering since I had to replace my cat a little more than a month ago.

somewhat, it's likely from the PCV system... make sure your PCV valve still makes noise when you shake it... if it goes bad I think you can have excessive oil consumption..

Yeah.. It still makes noise.. I shook it when I took it off to change out the rubber piece connecting the plenum to my SC

Looks normal to me.
Do you still have your EGR hooked up?

I could be wrong but the SC could be forcing more oil then what you would normally see with a N/A car
I think Aaron or maybe someone else said they had to switch to dual catch cans because of that.

I am fairly certain that with the pcv system all cars will get some oil up in the intake.

Yeah Phil. I've never done the EGR delete even though I have the parts to do so.

Matt it is just crankcase vapor buildup , totally normal Actually better than most !!! Don't worry !!

OK. Phew. I guess it's better to ask something stupid than have something going wrong w/ the car

This is why it's a good idea to delete the PCV and install a catch can on boosted setups. The purpose of the catch can is to capture blow by.

Matt, what they're not telling you is your car is junk now. They don't want to tell you.

Might as well just give it to me, and move on :D

For SC'd or turbo'd?

I suspect both as they both force more air in which then creates the likely hood of more air passing the rings

Yeah, that looks like pretty normal build up from the PCV and EGR systems. A catch can in the PCV line would probably reduce that a good bit, but not totally eliminate it. It's not an issue though.

Well. I guess I stripped the lower bolt/threads reattaching the elbow to the plenum yesterday. Started throwing the P0171 code (too lean), idles rough and it has a whiney air leak.. :-(

I can spin the bolt w/ just a socket head using my fingers...

Gotta go hit Pull-A-Part

You might have stripped the plenum itself, may need to be helicoiled.

Never heard of them. How do they work?

lol at the scooby doo remark.

Basically its a stainless steel coil that replaces the threads. The hole needs to be drilled out and using a sti tap to insert the coil. The kit will supply you with the bolt needed too.

You can find a good read through Google that can explain it better than I can, but that's basically what it is.

Yeah, helicoil might work. Also, if you have a thread tap you can drill and tap the holes deeper. I did that with mine because the bolts they used in the original SC kit didn't go all the way in the holes. I drilled and tapped them all the way through the UIM flange and bought some longer bolts to go in there. That way there is less chance of stripping them.

Might want to do that either way, whether you use a helicoil or get a new mani, or both.

I would try Aarons way first, a little less involved and if you can go deep enough to get a few threads, that would be sufficient enough.

In a month or so I can get a plenum powdercoated white for ya if your looking for one. I don't know if yours is ported or anything, but if it isn't then we can make something work.

I went ahead and snagged a good UIM from Pull-A-Part for $10. It was off of a 99 GT HO. I think I got it off the engine in 10 mins... lol.

One of the guys working there was like.. " Damn.. you know what you're doing." so I told him I've pull the UIM off a GA a good many times... lol lol

I went w/ the whole UIM because ALL of my flanges are cracked... ;crap



I need to go back and snag the steering wheel since it has radio controls on it... lol

You might as well get the clockspring too Some have different connectors from 99 to 02+

i got a wheel you can have, just pick it up when you drive through.
you will need your clockspring and cruise control

l

do you still have the egr setup on your car because if you dd the way the 99 one bolts to the manifold is completely different than the 00+ setup. functions the same but the egr and egr pipe mount is different.

should have stuck with the 00+ upper intake setup. since see the pic below that little indent translates into a shelf inside the neck.

OK Geldartb.... Does the EGR hose connect to the EGR the same way?

geldartb
04-17-2013, 07:19 AM
bolting the exhaust manifold yes. bolting to the intake manifold no.

the one on the 00+ bolts to the manifold with 1 bolt. the 99 and older one bolts to the intake with 2 bolts. the physical mount on the intake side is completely different..

99 setup number 10

one good thing the plug on the engine harness is the same between the two.

Finally got a correct plenum and the inlet running to the EGR had gunk in it and the opening itself was stopped up w/ carbon or whatever. I know when I took the EGR off, it had water or whatever come out of it.

I used some MAF cleaner to clear it up and got most of it. I need to spray more into it. Still getting some gunk out. Would blowing some compressed air into it help out?

You can use a tooth brush to get in there, that works well. Just don't brush your teeth with it. lol

That stuff was hard. I had to use a screwdriver to break it loose. I guess they can get severely clogged. One of the clerks at Advanced said he had one do that too.

Hmmm, sounds really built up. I take it, it has never been cleaned before?

Try some carb cleaner and a wire brush, that should do the trick.

back with my old 3100 in the Z26 i used a coat hanger to clean the hard stuff out.

with the older style egr's like the ones on around 1995 3100 cars it was kinda common to have that plugged up with crap. usually if it threw the egr code that was the problem.

AaronGTR

Yeah, they get so built up with carbon deposits like that because the PCV inlet is directly across from it at the top of the UIM neck. It drips oil down there which gets burned by the hot exhaust gas coming through the EGR and turns into carbon deposits. That's why I recommend installing a catch can in the PCV line. It will cut down on that quite a bit.

PhantomLover007
04-20-2013, 02:54 PM
Got everything fixed.

No more whistling from the air leak because I wasn't able to tighten the bolt correctly and causing me to get a lean code and making the engine run rough.

Dealt w/ this for a wk now... lol

Yeah. The sad thing was that the UIM I took off was ported... :-(

Also on your steering wheel swap, since I did that a few months back, I was able to remove the old clockspring and all its wires, and install the new one without removing the dash, only the gauge cluster and its backing plate, makes it a lot quicker job.

Are the clocksprings and wiring different?

I thought they both would use the same wiring.
