I'm sure the topic of reuseable valve cover gaskets has been gone over more then enough in the past few years but I just feel compelled to share my experiance of not knowing what the good ones were & the danger of it. I did buy & use a set of the brownish rubbery kind & I don't want to look up who I bought them from as I don't want to do any "Seller Bashing" I just want to share that they were very flimsy, baked into crisp parts that fell into the head the FIRST time I opened the covers so I was not going to try the "reuseable" kind again but after hearing the "red silicone" kind that our member Rockypoint sells were good I bought a set and I would like to say that they are Night & day differant from the flimsy brownish rubbery kind I had used before. I can tell allready that the red silicone ones from Rockypoint will be more user friendly & not turn into crispy broken little pieces falling into my valve train when I check my clearences next time. Just wanted to tell anyone who has used the flimsy rubbery kind, get them off before they get to old & toss them in the trash if you haven't used them yet!!!
