What to do with this???

[dparsons1968]

Just removed my LS1 intake to install my LS6. This is the first time I have ever done this but for some reason, I don't think this is what it should look like. Could I get some help with all this junk underneath my intake. It reminds me of the engine sludge commercial. I already broke the oil pressure sending unit. Anybody with some tips before I start the install of the LS6. It is already painted so I don't want to jack it up.

Thanks.

D..I would just shove some paper towels down into the intake ports and spray the living hell out of it with Brakleen.. No big deal.

So, the way it was when I took it off is close to normal?

yup thats what it will look like. if you do a PVC delete with a catch can it should keep it a little cleaner inside.
+ 1 for the brakleen, just try not to get any inside the motor. I dont know if your motor is clearcoated or not, mine was but the brakleen disolved it off

Use carb cleaner to dissolve most of the gunk, that way it won't hurt anything if it drips down into the intake ports.

Then to finish it off plug off the intake ports with a towel or rag and use brake cleaner to get rid of any residue left behind by the carb cleaner and give the intake gaskets a good sealing surface.

Thanks for the all the help.

Suck up the loose stuff with a shop vac.

I hope you are planning on installing the LS6 coolant crossover pipe!

Or grinding down the crosshatching on the bottom of the manifold

Thats what I did, and it worked great. No need to swap coolant lines or anything.

Actually, I ground down the webbing under the intake also. I never though I had a problem until I installed my Procharger. The intake was actually leaking, even before the supercharger install. I also had low vacuum and I found out by noticing oil around the intake ports. I put on the LS6 coolant crossover and my vacuum went from around 12 to 21.

how do you measure the vacuum?
well just thought about this too...wonder if TCW-3 that sarge is talking about helps clean that type of shit off....
and which way is the intake facing in the pic? is that the front of the intake on the right side of the picture. it looks like it's more built up on the left side and when I changed my plugs..it "looked" like the front plugs where "cleaner"

I'll have to check that out, but I thought for sure it cleared

Did you grind all of the webbing all the way down to the bottom of the manifold, or did you cut a path through it to allow clearance for the cooling lines??

[dparsons1968]

I installed the coolant bypass lines. I didn't want to mess with cutting down the ribs under the intake. I have started running the TC-W3 in my fuel but, with 124000 miiles on it already, I hope I don't have to take off the intake again to see if the two stroke oil has cleaned it up any. The gloss black, paint looks great. I will post up pics in the engine bay area when I get the fuel rail covers back on.

I cut down the ribbing to the intake base where ever the coolant lines ran.

Thats weird then. I don't remember mine having an issue with clearance.

Yup, mine seemed to sit flat too.

Hey, I have another question for you guys....while the intake was off, I noticed that there are 3 lines connected behind the intake. One coming from the driver side valve cover and then 2 lines coming from the passenger side. One from the valve cover and one, I think, is the PCV line. Please correct me if I am wrong. Anyway, all that for the question. That connection in the back is jacked up. It is about to be completely broken off where the two lines from the pass. side meet with the one line from the driver side. How worried should I be about this and should I fix it before I drive it anymore?

Thanks

Since you got it apart, it would be much easier to fix

[dparsons1968]

I have already put it back together. I can still get to everything as long as I leave my fuel rail covers off. I don't even want to know what the dealership would charge for those 3 hoses.
