blown cam seal

[byebyebaby]

ok im pretty sure ive blown a cam seal again on my d16y5. now the thing is i just replaced it no more than 2 months ago with a oe one from the local honda dealership. the original one only lasted about 6 months when i rebuilt the motor but that one came with a ebay gasket set so i knew that was coming. my question is what can be causing me to blow a cam seal so soon?

if your camhasft is worn right at the spot where the cam seal rides then it's gonna eat the seal, also if there is a burr on the shaft where the seal rides you are going to have the same problem, you may need a new cam.
