I have a set of jv plugs ready to install on a 2.6 Problem is that the o-rings were toast when I' pulled them from the donor engine. Do I need actual high temp o-rings (which seem to be quite hard to find around here, everyone wants to sell mass qtys at a time only). OR, can I just goop them with a good quality high temp sealant that is oil/fuel compatible?
