The Volvo B230 valve cover has to do a lot of tricky things to work properly. This gasket is a fair price for a substantial gasket. It still cracked slightly as it made those tricky bends over the cam rise and I still had to use RTV sealant to prevent future leaking. The term "rubberized" is misleading to me. The gasket is not as flexible as the term might suggest. In the end, this gasket is still a decent gasket at a fair price as long as I don't expect that much more from it than from other leading brand gaskets. On flat surfaces it is excellent. On the B230 bends it performs like the rest.
