Tips?

I have had lots of help here with intake swap questions. I was told to not use the cork for the front and rear gaskets but instead use a nice bead of Ultra Black. The more knowing of this site will chime in about your issue. I had a very small leak start a few weeks after doing mine, but I was told to clean the area really well and apply a bit more sealant and it worked great, that was without removing the intake.
