damn it, get it on the road and then have a potential head gasket issue, white foam in res tank, and every so often it blows some water out the res tank, also has a miss when warm at idle and im 3 psi short of top boost, also some bubbles coming out when cap off. no milky residue under cap or smell in radiator/res tank or white smoke from exaust and doesn't overheat. though I know this doesn't always happen, depends were it cracks? going to have a decent look and do a compression test.
