Redtop SR20DET swap problems HELP! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Just finished the SR swap. Spent over a year rebuilding the engine and of course, now I have a problem. Filled up all the fluids, plugged in all the connections and check the grounds. unplugged the CAS and cranked for a while to lube it up and while it cranks it has a distinct hissing sound, which I think might be a valve not sealing properly. Maybe due to the timing chain being off by a link or two. Also, when I actually cranked it it just ground to a halt, like the starter solenoid didn't retract itself. Any way to check its functionality?

I dont know whats going on, but what I do know is that I shouldn't be cranking it after hearing these noises. There are links to the videos below. Someone help!

And I had this thread posted on 240sx.org for three days and NO ONE has any ideas. Or they just don't care. Somebody hook me up with some advice por favor!
