WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

Well, I think I blew the motor or POSSIBLY something in the tranny. It's just ------ weird how it went.
Story....
This afternoon I did a compression test. 180 psi across all 4 (nearly perfect)

I was following the GF back to her house. From stop, I slammed on the gas, the revs rose fast like normal, but right at 5500 RPM. KABOOM! Sounded like something POPPED (cept really ------ loud), and then it sounded like a chunk of my downpipe was dragging underneath my car for a while. Sounded exactly like metal dragging and bouncing off the pavement, which I thought was wierd as ---- (usually you get the rock sound from the oil pan). The oil light went on, and I believe the car shut off (which made the light go on just like when you kill the car), but something was still spinning(grinding?) and finally the engine just seized.

Almost everytime i've seen or heard a car blow up there was a puff of smoke, the sound of pebbles being ground around in the oil pan, a hole on the block, and ---- leaking/stuff on the spark plugs.

Well, there was ------- NOTHING. I pulled out the dipstick. Oil looked perfect, spark plugs were great, No hole in the block. No antifreeze spilt anywhere. No puff or cloud of smoke when it blew. Timing belt seem ok from where I could look at it.

This is what's making me wonder if the pressure plate/clutch/or i guess (although unlikely) the flywheel basically exploded jamming up the tranny and in turned binding up the starter so the car couldn't turn over.

Ill have it back home tomorrow and torn apart by the end of the weekend, I ill let you guys know what happened, but until then.....

ANYONE HAVE ANY IDEAS OR EVEN EXPERIENCES WITH WHAT THE HELL MAY HAVE HAPPENED?!

Thanks

Dan :) Any questions feel free to ask. (And I just brought back my spare engine this afternoon, what kinda luck is that? :P )

wow sounds like fun. maybe it is just something in the drivetrain. i hope u take a lot of pics, good luck

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

so the engine is seized? try turningit over manualy at the crank first. Yeah, you probly broke something inside the tranny, does the car itself move? how about when in gear?

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

Yeah maybe an Axel snapped or something ??? Not sure why a CEl would come on because of that, but who knows. Let us know what you find, this is interesting.

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

he never said a CEL came on.

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

Thanks for the replies guys!!

I actually am thinking know that the timing belt skipped teeth. There was a loud sound (kinda like detonation) and then the metal scraping noise was probably the pistons hittin the valves. :(

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

was the timing off when you looked at it?

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

Tough break dude. Good thing you are experienced in blowing motors up. Is it completely sized? Can you turn the crank at all? Try and go a few rotations (if you can) and see where you sit. Don't forget to pull the plugs first so you don't have to muscle it on the compression strokes.

Oh yeah, I think you have your title backwards.

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

check the timing and drop the tranny if you think it blew up.

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

Sounds to me like broken valves. :-\

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

i say T-belt.. hope it works out for you tho :-\

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

Well obvisoly its not seized because he wouldnt have been able to do a compresson test.

I'm curious to see what you find.

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

Where was it mentioned that a compression check was ran?

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

Damn, he listed that ---- right in the top of the story, I don't read that intro crap. Ooops :P

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

im gonna say you blew something in your differential. same thing happened to me except the big bang.

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

lol i did the compression test that afternoon and blew it that night ;D Kinda sucked though :-[ Also, the engine was seized after it happened.

Heads fine but here's my update.....


Got the turbo stuff off, head, and oil pan off. 6hrs wasn't too shabby :P

The #4 rod is in pieces, the wristpin was blown off, and that whole oiling assemby or whatever it is in the oil pan was busted to hell in the #4 cyl. Also the bottom of the sleeve was busted off too. (prolly where the rod hit it). (pistons did make contact w/the valves in #4 as well. OHH WHAT A SITE IT WAS!!

The top of the pistons were in great shape thought which was kinda odd. Block MAY be salvagable too, ill have to see.

Ill have pics tomorrow, just haven't gotten them uploaded quite yet. 138,000 on the motor. 10psi. I was at about 24+ degrees on the uberdata map at 10psi. I

There's no wear on the bearings or rods though which is screwy, so I dont think I spun a bearing :crook:

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

24 degree's of timing!?!?! wow.. thats alot.

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

lol it was fun while it lasted...TRUST ME :)

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

AKA it was worth it?

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

I plead the 5th :P

Although smoking that WRX on the freeway did put a smile on my face :)

Gives me a chance to do a bunch...
It allows me to put on a thicker gasket, change the anti-freeze, change the oil, rip out the Power steering, put in a manual steering rack, put in the walbro fuel pump, and lastly put in the 6 puck that I never put in. haha all at once 8)

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

It happens i guess. Good outlook though! good luck with your rebuild

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

lol.. I like the power steering rack without the power stearing hooked up, way better feel of the road... Lol.. change the anti freeze.. haha oil hahaha

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

haha thanks guys.

YUP! it's an awesome feeling! I've been running w/o a belt now for a while. It feels solid actually. The only thing I can't stand is all the added weight :) Also it takes up a bunch of room too.

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

24 degrees? i dont get that part!

advanced? retarded?

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

probably total timing son.... 24' btdc total timing

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

thank u daddy.

that means time was advanced cuz stock timing is around 18 or something? I really need this clear. I gonna be using a timing gun next week on my car.

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

stock timing is 16 degree's buddy. meaning he was 8 degree's advanced. holy ---- thats a ---- load. hahaha. sorry to say man but u were asking for it. good luck on the rebuild though

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

nononononono :) You guys need to understand this :) The stock honda ecu advances timing. in vac it would start at 16 degrees advanced and then advance to 28 degrees at 0 psi (N/A). W/the boosted motor I was running 24 degrees at 10psi. 4 degrees retarded from stock 0psi (N/A) = 10psi (turbo) sorta. (kinda like your running the hack w/ 4 degrees retarded at the dizzy. Idk if this makes sense. It's not a CRAZY amount of timing, but it was certainly more than I should have been using for daily driving :)

Does this clear it up?

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

pictures?

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

So what is safe so that I won't blow up my z6. Cuz I have heard that they take alot of boost but I have to beat my friends crx with 230hp. At the same time I don't want to put in a new engine. And how much hp were you getting out of your sol?

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

ohh lol I forgot, yup there are pics, i just can't find the site my friend hosted them on. Ill have them once he gets back from work :)

Also, .75-.9 deg/psi is a safe retard (when runnning higher boost)

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

that kind of scares me...according to my uberdata map i'm 18* at idle and 27.75* at 12psi at redline. haven't heard any detonation, afr is rich, and egt look good too...at least 100* less than when i was running the hack.

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

How long have you been running that map? 27.75 is only retarde 1 degree at most. Send me that map. I'd like to check it out. athlonmank7@hotmail.com

That's a shitload of boost for that kinda timing haha. But if it works, more power to ya (pun intended :P)

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

well think of it on the bright side now its time for a fresh and stronger rebuilt. i blew my stock 1.5 2 months ago after only running it a week, but it made me faster cause i ended up putting a 1.6 vtec and now im much more happier ;D 6psi the most now.
but you should know the 1.5 blew at around 15 psi overboosted on its own, my rods flew out my block and hit my fans/turbo/manifold/radiator support and one came out the back and hit my firewall, all i could do was laught when i saw it lollolol :( at least you can still use that block for a rebuild.

Re:WELL, I SOMETHING BLEW! D16z6 @ 10psi no more. It's just a little odd.......
 

Welp it's been a while and I figure I better update.
I finally figured out the reason it blew at 10psi.

I was actually running stock timing! (YAY ) Why you ask? Im not going to admit why

It lasted for about 1 month on stock timing and 10psi (driven every day)


As far as the engine's going. I got uberdata's new map/clutch/PS out/and ss in hehe. Also Got my new engine in (just need to put on the head and turbo stuff and im pretty much done

Can't wait to boost it again. I've got pics of this, but i forgot where they're hosted


So I just wanted to reiterrate B/C I think I scurred some ppl. The engine blew because of HUMAN ERROR (AKA STOCK TIMING)

RIP Block #1

20days ago...

and still no pics... :-\

make sure non of that metal shaving got in to the turbo oil feel lines, or worse, the turbo itself.
so clean/flush all that out before u start again.

good luck
