I have a quick question about the front part of the oil pan gasket. My stock gasket is rubber and I think metal. It extends to the front of the pan. I had to use a putty knife on these ends to break loose the timing cover. Can I just use some RTV sealant and put the cover back on or do I need to cut these sections out and put the cork gasket tabs that came with the timing cover gasket set? Here's a pic. THX
