LT1 Oil Leaking (but from where!)

LT1 Oil Leaking (but from where!)
Hey-
So I've been plagued with an LT1 oil leak. Surprised? Probably not.
This one's in a weird place though. The oil is in the grooves on the valve cover (passenger side), and when I run my fingers down the back of the intake manifold there is no leak there, nor on the back of the valve cover.
I replaced the valve cover gasket twice, and the valve cover once... to no avail. I'm going to buy some oil stop leak and put it in tomorrow when I change my oil.
Is it possible that this oil is being sprayed out of the dipstick, or something? I just cant seem to understand where anything could be coming from that fills the grooves on the valve covers..... other than the bolts on the valve covers or the dipstick? I'm running over the valve cover wires... which kind of have a built in washer on the bracket that holds the wires, too.
Any input is appreciated. Thanks
Jens

i highly doubt your leaking oil out the top of the dipstick....im not really familiar with the lt1 motor....you might try asking some of the guys in the lt1 section for a little help, because if your not loosing it through the head seals, but thats where its coming from im a little lost considering this is near the top of the motor and you dont really have oil coming above that lol

well if your leaking oil on the passenger side where the dipstick is did you ever check your pcv valve? because i know mine seaps a little oil from the pcv where it goes into the valve cover and kind of makes a mess out of my valve cover, check that out

thanks! i did the following today:
replaced the o ring on the oil fill cap
changed the oil (with some lucas, to maybe hopefully make it stop leaking)
is there any way to identify if its transmission fluid thats leaking-- and not oil? i know the tranny fluid is red.. but even after it gets dirty is it still red?
