What recommendations does everyone have for troubleshooting an evap leak?
After relocating the EVAP canister with the MetalCloak bracket, I immediately got the gas cap warning. A couple of trips later, it turned into a P0457 check engine light (EVAP system leak detected).
I checked that I'd tightened everything, cleared the codes, but got the gas cap warning again as soon as the key was in.
I took everything off and put it back together again, with a helping of silicone grease for the o-ring on the vapor leak detection pump. I tightened everything up again, cleared the codes, but again got the gas cap warning, which turns into a P0457.
Before I buy or build a smoke test apparatus, are there other things I should check? Should I worry about the slight kinks in the bottom left evap hose? I was inadvertently rough with the leak detection pump to clock it for installation, and it looks like the silicone grease has come out from that o-ring connection. Should I duct tape it up to see if that's my leak? I've also got my eye on the connection from the hard tube coming from the fuel filler, where it connects to the rubber hose to the evap.
Which steps would you take next?
