Question on LS6 intake issue Swapping the intake off a 2003 LS6 with 120,000 miles and I notice years of oil build up caked to the inside (assume from the PCV). I clean with degreaser and lots of hot water but there is still lots of "rough spots" and some build up I could not reach. And before I get the wise cracks , yes it was off the car. 
So the questions are........
1). How much will this effect Hp/Tq?
2). Is it worth cleaning it out back to like new?
3). If I do need to clean near perfect, what should I use?
BTW, engine will end up being forced induction down the road, if that makes a difference in your answer. Thx

Brake cleaner does a good job of breaking down that kind of build up.
Residue in the plenum chamber will have very little affect on torque/power, but residue past the plenum might have some.
Residue may come off in time and run thorugh your motor, but I cannot see that being a big deal.

i had mine cleaned in a CUDA [its the big parts washers with the high pressure nozzles and hot soapy water solution] it came out flawlessly. if you know a mechanic or a machinist chances are theyl have access to one and it will save you alot of messin around. or any machine shop would clean it for a small fee.
