So I bought a gasket kit for the valve cover on my 2k neon which comes with the tube seals, I wanted to replace them anyways because I had a little oil on my spark plugs, well guess what?? those suckers weren't coming off

, I tried pliers, flat head screwdrivers, razor blades and I was able to get most of the seals off, but the part were the bottom of the seal makes contact with the valve cover its not coming off I think some1 used some sort of super/crazy/cement glue

, I used paint thinner, goo off/gone, and a number of other chemicals to get it loose but nothing works I let the seals soak for 2 days in the chemicals and........ nothing

, and everytime I try to use pliers or screwdrivers or whatever the POS valve covers either get chipped or deform or I get very small(tiny) amounts of plastic stuck to the left over parts of the rubber seal

.
Now I don't even know if I should waste anymore time with this crap since I've been only able to remove 1 full seal.
Any suggestions????
I thought about the junk yard, but I'm almost sure I'm gonna run into the same problem, plus the lady that runs the junkyard thinks she's running a dealership and charges ridiculous amounts for the parts.
I saw the mancini racing metal valve covers:

But I read here in the forums that they were no longer available, its this a scam or can I buy 1 of those with confidence???
Any comments and input would be appreciated.
