Ok whats up everyone so my 335 has a er charge pipe with a synapse bov on it. i started putting my car back to stock put the stock intake back but left the Charge pipe cause i thought the dealership wouldnt notice it and they didnt
but now the BOV stopped working about a week after i got it back, so i took the stock intake box off and put my dual cone intakes back on and it helped the bov work alittle better but still not 100%. So my question is whats wrong with my BOV im thinking maybe it needs to be relubed??? or do we not have to lube them.... other then that i cant think of anything else thats could be causing it. But there is some oil around the BOV tip but thats usually for turbos no? my 240 does that also and all my friends with turbod cars said its normal but idk about BMWs.... so whatever info you guys go will help thanks
