C7 Corvette General Discussion
2003, C5 1600miles. check engine code 410, PCV air valve malfunction. Told to put 1/2 can of Seafoam in gas tank and 1/2 in engine oil drive for 50 miles. reset code, repeat every 3rd gas fill up. This is common on LSC engines in humid climate that aren't driven a lot. What do you think?
