I have a fully built 95 Gsr head on a 2000 b16 block new timing belt and every bolt on you could think of .I had a few problem getting it to run properly ,fuel leaks,upside down head gaskets ,bad speed sensors the works. I finally got it running, idle was perfect fuel pressure was fine no more leaks and vtec was popping of hard as fuck,9200 rpms lovin life.
I pull up to a light im at idle you know 900 rpms to 1000 chillin and the car just dies , i (like a dumbass) thought it was a fuel issue cause i was low on fuel thought i ran out of gas so i kept cranking the motor over and over again nothing. I pop the hood get out check all of my wiring (fine) check everthing else good . I have a cut valve cover i look there and the exhaust cam is pointing straight up 12 o clock the intake is pointing towards the firewall at 4 o clock . What the hell could have locked up/came loose to cause this , i haven't torn it apart yet but the t belt has plenty of tension everythings snug. Im praying i haven't already bent those pretty stainless valves but what could have caused this? ANY IDEAS guys please . No shit talkers please.

 

how do you put a headgasket upside down?the bolts wont line up...but sounds to me like your tensioner is loose or the spring is not there

 

No all the bolts line up thats the trick it was dark and i couldnt see the shiny word up on the gasket that lead to the most insane oil leak ever.
