Hey guys

I just replaced my ABS and my radiator recently (within 3 weeks). Last week I got a check engine light and it turned out to be P0455. I am 99% sure it is not the gas cap but I am unsure what it could be. When I replaced the radiator the mechanic also mentioned that I may have blowby occurring and I think it could relate to that as P0455 is an emissions issue. Thanks in advance!

The P0455 code indicates a large EVAP leak. There could be quite a few causes for this, such as cracked hoses, bad shut off valve, bad purge valve, bad charcoal canister etc.
I would recommend doing a search here since this has been discussed a few times.

Most likely cause of evap code is a broken hose. They are 15-16 years old!!

It's easy to break a hose during a radiator job.

I don think blowby is causing your evap code but that's more serious. If you pop out the rear main seal you have a 1005 USd repair at hand...5 dollars for seal, 1000 to remove/replace engine

I am going to look at the hoses later today then. as for the blowby... I know. I don't want it to come to that but I love this car so much and really do not wish to get rid of it
