whats the problem do you think?

i was out and tuning my afr, i have a real safe ignition map i had around 11-12,0 when i pulled 4th gear it was a boom and the car shouts down, i have allot of smoke coming from the catch can.
when i finally found someone that could help me home o checked the comp and it was
1 8,0 kg
2 10,5 kg
3 0 kg
4 8kg
the 3ird had allot of water on the sparkplug and i have allot of water in the oil
the headgasket is very gone but do you think that the sleeves are gone to?
if so. whats the best to do? buy another block or new sleeves

the setup is
b16a1 obd0
garrett t04e 57 trim
blox manifold
cp pistons 9,1
eagle rods


here is a video when i try to start it

Only way to really tell the condition of the sleeves is to get the head off it and visually check the sleeves.

Sorry for your lost man.

What are you using to tune your car by the way?

 

I'm no expert but it looks to me like the piston to wall clearance was waaay off and when the o pistons got hot and expanded boom!

 

i had it tuned with bre, i had a total timing at 16 degrees at 15psi
afr 12,0
i had the cp pistons for 2 years the last year it was tuned with afc hack

 

You just answered your own question man. AFC Hack.

That **** will destroy any pistons man, I went thru that just look at my old motor before AFC and after AFC.




Detonation man that about sums it up.

 

but that was 6 months since i thrown away the apexi

Were you tuning the timing or were you only looking at the wideband?

Because your afr matters much, MUCH less than the timing when it comes to blowing **** up. To me it looks like it got real hot from detonation and melted. Surprised the sleeve didn't go though.

Sucks

 

i was only tuning the afr.
can a bad injector do something like this?
i had som igniton missfire and i bought new sparkplugs and ignition coil but it did not go away, then this happend

i will probably buy another block. but dont know wich one yet

 

Go look up that 560whp STOCK BLOCK B16. They busted the ringlands after a few pulls and quarter mile runs, and it still ran okay and had power.

Yours probably got to the edge of their life with the afc hack, then 15psi with better tuning took those fragile CP's to their death. To their credit, they probably gave you some extra time before going poof.

If you aren't 101% sure your engine maintained at least 12:1 AFR's during the whole pull (with datalogging to prove it), chances are it leaned out and blew. When #3 goes first, thats a good indicator of it leaning in all 4 since #3 runs the hottest.

 

ok.
can i still use the cylinder head? there is som nasty marks on it.
what should i do now. whats the best to buy, i am only lokking for 350-380 whp.
should i just get another b16 block or buy some sleves? is there any b18 block that i can use?

 

you may be able to salvage the head, but its probably eisier and cheaper to get a new/used one. Thos sleeves are done though.....

From what I can see, the Head looks fine. The small marks are not going to do a whole lot. I would sand the marks a bit to smooth them down to keep from developing hotspots. Then drop the head off at a machine shop and have the valve seats recut.


My machine shop actually wanted to try and fix this one. She was toast though


Good 'Ole number 3

 

What engine management ?

 

my engine management was BRE
here is som more pictures

what do you think of the oilpump end the crank bearings.
these thing have runed 300, 000 km
