What just happened?!
 

Ok, before any of this i was pushing 10psi, so i was rearranging some vacuum lines and moved my MBC closer to the turbo. I drove it down the street, 1st gear pulled like crazy, 2nd gear pulled even more, i hit third and heard a weird noise (cant remember how it sounded like), i got to a stop sign and notice that my car was off...i tried cranking it and it wouldnt start. So i thought i most of blew the motor because MBC was probably pushing for than 10psi, (my boost gauge wasnt working either, after i rearranged the vacuum lines, so i didnt know how much boost i was pushing) so i called my brother over so he can help jump start, IT DIDNT EVEN JUMP START! i dont know whats wrong with it. One thing i notice is when my brother was trying to crank it, there was oil leaking out where you plug that pipe into the intake, i thought that small pipe suppose to suck in air, but it shoot out air and small amount of oil. Help please...whats up with my motor....

D15B7/RHB5 @ 10psi
check valves/FMU

damn, doesnt sound good. i know the "breather" is to help cool the head. oil shouldnt shoot out from there. ive heard of this happening before. what was the sound you heard? was it like a pffssh or more like a bang or crack?? if it made a wierd blowoff noise probably one of the charge pipes popped off, but you should still be able to start the car no problem. check for any defects in the block like a piston shooting threw it :-X. check the turbo oil lines to see if they didnt pop off or anything. does it even crank over or no spark at all???

Re:What just happened?!
 

is there oil leaking from the block too?...and the breather is to do just that, let the head/crankcase breathe, some oil will come out, more if you have blowby (you might have fried a piston)

Re:What just happened?!
 

ring lands

Re:What just happened?!
 

my friend said its a blown head gasket, i bought a head gasket but still not to sure its that...

Re:What just happened?!
 

and yes, it does crank, just doesnt start up, and where the intake pipe thingy plug where oil leaks out, steam is also leaking out too, well...it WAS anyways.

Re:What just happened?!
 

the weird thing is, i wanna know why my car shut off in 3rd gear.

Re:What just happened?!
 

dude.....fmu check valves and 10 psi. theres your first problem. secondly it sounds like you roached more than a hg.

Re:What just happened?!
 

yea i know, CV & FMU, but it ran fine at 10psi, im guessing it was pushing a little over 10 that time but yeah....still not sure whats wrong, i took off the valve cover and was trying to look for water spots, nothing.

Re:What just happened?!
 

theres no way your car will hold together at 10 psi or more on a fmu. sounds like it already let go

Re:What just happened?!
 

MBC is your problem, gotta be very careful with those things

Re:What just happened?!
 

sounds like the headgasket or ringlands. i'm not sure what happens when you spin a bearing but i think the same thing just happemed to my friends b16 and its stuck somewhere and wont start :-\

Re:What just happened?!
 

Ive been here before, same thing happened to me, you probably toasted the rings, because theres no way that 10+ psi and an FMU just doesnt match... was it just oil coming out of the hole in the back? or was it smoking too? cause smoke usually means blowby, which more than likely is your rings. -Ben

Re:What just happened?!
 

Your engine won't start cause there's no more compression....

Re:What just happened?!
 

get a rope and hang yourself, your motor is gone fool

Re:What just happened?!
 

another d15b7 bites the dust :-[.... ---- i got a hole in my block.. but my car still runs...(awwww got to love a honda)

Re:What just happened?!
 

thats what happened to my car in third gear it quit.blew all four pistons. damn ringlands. >:(

Re:What just happened?!
 

yeah dude you blew your ---- up. you are insane for running 10psi and an fmu. ---- man they dont even belong in the same sentance.
