I've taken my 22 hp 2001 Intek engine ( V twin) apart. The valve seals were leaking and causing a lot of smoke on the start ups. I have the heads off, and have lapped the valves, and it looks like the intake and exhaust are different regarding the valve seals. It seems the kits for engine rebuild seem to come with only 2, so which one is replaceable? It looks like maybe the exhaust, cause it's in a lower position than the intake. I'm getting ready to order the parts to put it back together, and I need to know how many valve seals to order. Thanks...BTW, this engine has almost 1000 hours, always with full synthetic oil, and the sump was perfectly clean.
