1st 2 times I take off the manifold, everythings turned out fine, now

I just put on a ported LE intake manifold, and now I have the famous rear intake manifold leak. I put a ****load of RTV on, and the car actually sat 2 days before I started it up, I don't know wtf I did wronge. I guess its coming off for a 4th time now.

This may be a dumb question but did you be sure and scrape off ALL the old gasket material? Then make sure there was 0 oil anywhere around where the RTV is gonna be? How are you torquing the intake? If you have already done this stuff disregard this post

I scraped it all off, I think i forgot to use brake cleaner on the surface material though. I torqued it down with the factory patern. I'm goign to cut off the headfs of bolts and use the studs to line it up this time.

Yeah, make sure you don't smear the rear bead when setting the intake down. I did that recently when I put the Nitrous manifold on. Had to pull it again the next weekend. After a few heat cycles retorque your bolts again.
