i recently bought a 2011 wrx from a friend. he blew the motor he had in it and swapped it with an ej205 when he had it. the motor has about 1900 miles on it and the first thing i did was purchase an etune. in the process of datalogging my tuner said i had a boost leak. i figured the boost leak had something to do with the mishimoto charge pipe i have so i pulled off the intercooler, intake manifold and coolant pump to get access to the charge pipe. i tightened down everything and put everything back together and when i went to start the car i can hear a light ticking on both heads of the engine(or around there) that matches revs. im baffled at what it can be because the engine has way too low mileage to be blown already. the car was also sitting for about a week and didnt tick or knock before that. any suggestions? thank you
