Can valve seals cause plugs to foul?
Here's the deal, recently I completed a cam swap to a Torquer 2. Everything ran alright, got a PCM flash to make it to the tuner, all seemed well. Come to notice that my car is smoking, mostly at idle, not so much anywhere else. After some trouble shooting, I find that there's fuel in the crank case. I smelled my dip stick, as did my wife who knows dick about cars... it's fuel.
I make some contacts, someone tellls me I should have replaced the valve seals, that they can cause excess fuel to get into the chamber. First off, I did not skimp one bit on my cam swap. This is a 25k mile, full warranty, brand new from GM 1 year ago LS1. I replaced the reccomended stuff, but skipped the seals due to the fact that I was putting beehive springs in and the seals were fine. I performed a compression test a month ago and compression was as perfect as it could get. The person I'm talking to says that there's no way my valve seals can work with the springs I have, and I should have changed them and that's what's causing excess fuel to get into the chamber.
My theory is that it's the tune on the PCM flash.... Does the theory that the valve seals could some how (even if they were in poor shape, I dont see how this is even related) cause excess fuel to come into the chamber hold any water?
Thoughts?

The main question is, can a weak valve seal somehow allow fuel into the cylinder?

The fuel is washing past the rings...get it tuned soon or your cylinders are gonna glaze badly. Who ever told you valve seals knows NOTHING! i say NOTHING.....
You could have a leaking injector but i sriously doubt it. If this problem just showed up after the cam swap you are running way too rich.
