YO' some neon heads (a lot) have been found to be porise(can't spell for
s***) any way it needs to be updated, think about the pressure leaking
into the cooling system, it mess' things up, i also have 4 GM's a VWbaja
2.2turbo

check out the deal on the head some were recalled
not all were taken back, YOUR ARE using new head bolts aren't you
