I broke many over the years ... I just drill them out and heil coil it then install a new stud...5 dollar fix..

Its a blown head gasket dont look for anything else..They blow out the left side so you wont get any water in the oil .....All you need is a head gasket, intake/exhaust manifold gasket and valve cover gasket.. I would change the head bolts too...thats it.. I would go with felpro..You cant beat the price.and it hold the same as nissan oem gaskets.. 22 psi they blow

I have a map for a f9 if it helps at all

I would'nt waste my time with the bottom end...Just change the head gasket and drive it.. Its a very familiar sound to me..Blown head gasket... I do recomend new head blots ...by the way oem nissan hg and felpro (autozone or advanced ) hold out the same..anything after 22 psi they blow out...
