Is This Normal??
I pulled my throttle body to install a ported one. When I look into the opening there was oil everywhere. I have since installed an oil catch can but should I go in and wipe out the oil I see behind the TB?

I just drained my catch can for the first time after a month or two and it was pretty full . Maybe 3 oz. I'd try and clean all that up that you can get to. But now that you have a can installed you should be good to go.

Yes it's normal, been happening since 1963 as far back as I go but maybe before that. It's only a problem on LS motor type forums, it's no problem at all. Catch cans = Snake oil. I installed an inline oil filter on my 320,000 mile LS1 to see what some are talking about and after 3,000 miles I had less that a teaspoon of oil. Oil is the life Blood of the Internal Combustion Engine. If it makes you feel bad then just spend $100 of more on something you really don't need....that should make you feel better.

If you want "ZERO OIL" IN YOUR INTAKE MANIFOLD, CHECK THIS THREAD OUT! It has been working for me for many thousand of miles now, it may of helped my car set a new GS "bolt-on" ET/MPH record a week or so ago. Oh, and save some money & no junky up the engine compartment.

I have put a ton of 1/4 mile passes since I installed the breather set-up and to this day I still have not had "one drop" of oil drip from the breather. I also just changed the oil with 5000 miles on the clock and the dip stick was still right on the full mark before draining the old 5/30 Mobil One.

100%. Add those conditions with 91 octane (CA) and performance will suffer with an increase chance of K.R.!

Nice, thanks to you and Spin!
I kept up tracking your post last year and Spins in the past on this subject, but I choose the catch can route for the Vette - mainly to enjoy the challenge of what I can make for it!
Maybe drag racing is different then Autocrossing/Roadracing? With all the down shifting, street driving is more similar to road racing, although to a tamer degree in dealing with blow bys. Roadracing crowds seems to prefer catch can, I am still not convenience. Am I wrong in my thinking?

All I can say is try it, if it does not work out for you just reinstall the can. However you will be 15/20 bucks in the hole.
PS: Spin makes me "Believable".

I have never looked at the LS7 but I would imagine it would be approx. the same setup.
