thanks,,appreciate the quick replies.
i guess a general clean up is in order then ( but perhaps not necessary) i figured that the fluid accumulation was a result of the egr system, so thanks for reassurance of that. i wonder, did you notice any problems prior to cleaning the manifold that prompted you to clean it, or was it a gee whiz thing?

 

[labattsipa]

just so we know what im looking at. here is the manifold with the top cover off. please note all the build up on the metal gasket

 

[labattsipa]

and here is that fluid i was mentioning note ;with the gasket removed.

and this is the bottom side of the cover plate. note the carbon buildup.

of note;
im trying an experement on this right now by running 2 cycle oil with my gas.
there have been some threads on this using synthetic TCW3 2 cycle oil as an additive in ratios of 1 oz to 5 gallon of gas.
based upon the research/hearsay this additive have benificial results when added to your gas, including restored power, lubrication of the top end, fuel system and cleaning of the ring packs and reversing the effects of carbon build up in the engine.
it does not damage the cat or the ox sensors.
when i pulled the top place off my intake manifold i only cleaned the bottom of the cover plate and the metal gasket (by the way, those that remove the gasket, make sure you put it back on in the correct orientation).
i have run 5-6 tanks of gas thru my car since i started with the TCW3. i plan to remove the cover plate again here in the near future and see if the egr is is cleaning up on its own.

tell ya what, go over to ls1.com and read up on a thread called "been testing" it has about 35 pages to it on the TCW3 issue.
look into it and see what you think.

yes, labatts used to make an IPA, but not in a long time. clear bottle and it was good.
the TCW3 is ashless so no residue by what im reading.
the claimed benifits are cleaning of the ring packs so better or renewed compression, lubrication of the top end, fuel system ( injectors). the mix ratio is so low, 500:1 that the oil is virtually completly burned, ashless, and no reports of oxygen sensor fouling or cat.
this is not claimed to be a miracle in a can by any means but more of a preformance renewer and another way to perhaps cheaper or for those that prefere to monitor for them selves and have more control over what is in their tank.
one person described the gas sold to day as being very "dry" as in there was none or little pressance of effective additives that would have a real benifit.
like i said, plently of good reading available on this subject.

i did pull the cover plate off and there was still crap in there, so far everytime ive pulled the cover off, i clean it and the gasket.
the carbon build up as far as im concerned is not drastic, but what looks to be normal. does this action of adding the TCW3 help to reduce it?
i can't see any evidence of it, but the TCW3 does help in other areas that are benificial. the clean up on the intake manifold would have been a bonus

 

[labattsipa]

im just going to throw this out there for all to address what ever way they want.. when i cleaned the metal gasket and plenum areas, i used carb cleaner,, not anything abrasive like a wire brush and a rag to dry up any residual liquid. i would think that a wire brush on the gasket or mating surfaces could be detrimental.

[labattsipa]

like i said, JMO,, i figured that you would use some care in how you handled the gasket and mating surfaces.

now that's impressive
