I think that rod had quite a few little dents in the top of it from whatever broke through the piston, is it ok to reuse at that point?

PMed.

Sweet geebuz I think this trumps Ryan's carnage pics!

Brandon, is there anything in your entire intake tract that may have busted loose? A piece of silicone coupler, fin of FMIC, etc? Part of the BOV perhaps? Looks like something small got in there and was obviously obliterated or it would have taken out the turbine on the way out.....did you check that too? :(

Was the car sitting for any length of time w/o something covering the intake piping/IM inlet? Perhaps something small fell in there as you were swapping TB's....Gasket material or something?

Dude this sucks pretty hard, and like I said before I have a head for ya. If you have time Thursday night you can come take a look at it if ya want!

Also, check the oil pan. Your culperate might be sitting at the bottom (fell through the hole in the piston)?

Re: Engine Clanking -WTF!!!
 

I wouldn't go that far, I mean I did break a piston, rod, crank, block, oil pan and head. Not that we need to start a competition or anything, this shit sucks.

As for the rod and dents in the top, I'd say replace on that. Are they big or small? If they are small, like you can see that there are dents, but it's not like in the head, then maybe. Rods are high stress items though. You should be able to get just one.

those pics make me grind my teeth, buhhh.

good luck with whatever action you take to the motor.

Re: Engine Clanking -WTF!!!
 

That is some crazy carnage, and it just makes me cringe. :(

Re: Engine Clanking -WTF!!!
 

Sucks to see this Brandon. What valves are those? Valve springs?
I would make sure you clean everything as that oil pan is going to be filled with debris.

Re: Engine Clanking -WTF!!!
 

Did a bolt or something get sucked in through the intake mani? I cant see how a piston would do that to the spark plug all by itself.

Re: Engine Clanking -WTF!!!
 

Find anything in the oil pan? Cheeseburger or perhaps a finger or something?

Re: Engine Clanking -WTF!!!
 

Judging from the pictures, it looks like pre-ignition.

As far as just doing a hone, go for it, if the cylinder bores are decent enough. That's all I ever do with my own cars. My 1G has stock bore stock pistons in a honed block and my 2G has stock bore Wiseco pistons in a honed 4G64 block. I did a hone in my garage with my first build on the original 2.0l engine in my 2G and that one was also fine until the oil cooler blew off and killed the motor.

Re: Engine Clanking -WTF!!!
 

They are just stock valves, with Crower springs/retainers.

Re: Engine Clanking -WTF!!!
 

I'll try and see if I can't get the oil pan off tonight, but I'm having dinner with the European guys so I might not be able to get it completely off by tonight.

Re: Engine Clanking -WTF!!!
 

I've got a couple different grit bottle hones if you need one, much better the crap they sell at Northern. I'd just hone it and drop in a new rod/piston, I think you'll be fine.

Good luck finding a used Mahle/Eagle combo, that's not too common. But you should be able to buy one of each new, I have before.

Re: Engine Clanking -WTF!!!
 

That's the first thing I thought as well once I saw the pics. But it also could just be from shit smashing around?

Re: Engine Clanking -WTF!!!
 

Maybe your tach thing has something to do with the spark plug. Looks like maybe it created a short to ground, maybe screwing with your ignition system?

Re: Engine Clanking -WTF!!!
 

I didn't want to comment as it really is difficult to tell with metal debris also.

It is a case of the chicken or the egg, the rest of the cylinders look okay. I'd maybe get the injector flow checked just in case.

Dude, THERE's your problem!!!

Re: Engine Clanking -WTF!!!
 

I have acouple of rockers too. But it appears that's the least of you problems

Re: Engine Clanking -WTF!!!
 

From what I've gathered from many others, is that OEM valves are of a 2 piece design, which means when they are built, they start as 2 pieces and are then fused together some how to create a single valve. And that is where mine snapped, about where they would have been fused. Apparently 2 piece valves are weaker at that fuse point as well. Maybe it was just old and ready to go, and thank god it atleast died at a lower RPM and only a couple blocks from my house, rather then at 8K RPM on DB's dyno.

Re: Engine Clanking -WTF!!!
 

What are you guys speculating (Shane, Mo, Swanny) about? Pre ignition causing the valve to snap and dominate the shit out of everything it can? Seems relatively obvious to me that this was a random valve failure. Even more so after what he just posted.
