It's not water. I've done that, it doesn't smash one plug.

Re: Engine Clanking -WTF!!!
 

The head is almost off. I'm just taking a break. Trying to keep all the parts as neat as I can because they may not be going back on for a looong time.

What I did find is that the turbo compressor wheel is in decent shape. I was thinking there was a chance the the compressor wheel was going to be missing, and is what entered the engine bay. Anyhow, it's there, and shaft play is still fine, and it spins freely likes it brand new. There are however, some small little imperfections at the ends of some of the blades. It's a brand new turbo and so I'm not sure why there are some rough edges on the blades.

What else I found is that I can easily turn over the motor by hand. I remember someone asking about that.

The timing belt was perfect.

I stuck an extension down the #4 cylinder, then stuck it down the #1. When I stuck it down the #1, it felt like there were more objects down there then just the piston :(

Re: Engine Clanking -WTF!!!
 

Did you check to see if the throttle body shaft fell apart or a TB plate retainer bolt came off? Since that was the newest mod, and throttle body breakage has taken out a fair amount of motors.

Re: Engine Clanking -WTF!!!
 

^oooh, good idea.

Re: Engine Clanking -WTF!!!
 

Checked the TB, all seems to be fine. Both the screws are in there, it still functions fine.

But I just got the head off. Thanks for the quick help Andrew


I think this may be a bigger tragedy then Romeo & Juliet...

Re: Engine Clanking -WTF!!!
 

Good news is that I don't think the block is trashed. The cylinder walls looked had no large gouges or anything of that sort. I'll be spending some time this week on the car, and removing the oil pan, and the rod/piston from that cylinder. Then I'll try to clean out that cylinder as best as I can, and get a better look at what condition that cylinder is in.

The head is screwed though, so if anyone has one laying around, let me know. I'll be reusing the Crower springs/retainers from this head, the cams, the rockers, and the 3g HLA's. The rest is just worth it's weight in aluminum I think.

Re: Engine Clanking -WTF!!!
 

holy fucking wow... apparently you had an emo valve that didn't wanna live anymore...

Re: Engine Clanking -WTF!!!
 

^word, any idea why/how that happened after tearing down the motor?

Re: Engine Clanking -WTF!!!
 

I'd like to get some honest advice here. If they cylinder walls aren't horrible, is this something I could simply rehone, and reinstall new parts into there? Or is this a must that the block be removed, remachined, the whole works?

Steve or anyone on here who is somewhat experienced with this, please help me out as I just paid a nice chunk of money to get this thing built maybe 1 1/2 years ago, the right way, from a shop, who did a great job, and now I'm looking at having to drop a huge chunk of money to get it done all over again because of what appears to be a freak accident that wrecked all this. If there are any ways to redo this nicely, but not having to go through the whole 9 yards, I am all ears.

I remember Scheides (I think it was Scheides) putting up a post awhile back about people rebuilding their motors by just rehoning them. Obviouslly they weren't motors that look like what mine looks like now. But if the walls really aren't that bad, could this be an option?

Re: Engine Clanking -WTF!!!
 

Right now, nothing. The TB is fine, the cams still look good, everything under the Valve Cover looked good except for the busted rocker (which must have busted due to the valve in the cylinder). No idea what caused the valve to fall into the cylinder. I'm still trying to understand why my tach stopped, and if that has anything to do with anything here. Did maybe that injector die or it's clogged, caused it to run lean, and voila? I will be hooking the injectors up to a battery to test and make sure they all still function, and will clean them with some carb cleaner.

Re: Engine Clanking -WTF!!!
 

Oh shit! :( Good luck with everything.

Re: Engine Clanking -WTF!!!
 

Deffinetly an option man. If the cylinder walls aren't scored You can hone the bitch with a powerdrill and drop in a new piston.

Is it going to be as tight a clearance as the other 3? No, but It'll get you down the road through the summer and then some. Is the rod OK?

I hope much metal didn't make it through your oil pump, turbo, bearings, etc.

Re: Engine Clanking -WTF!!!
 

Maybe when I get everything cleaned up in there, I'll try and get one of you smarter engine folks over here and take a look, and give me some words of wisdom.

Re: Engine Clanking -WTF!!!
 

If the cylinder walls don't have any major scoring that your fingernail would catch on, you can rehone it and drop a new piston in there. It really depends on the condition of the cylinder wall. Being that the piston has an actual hole in it, metal fragments are most likely in your pan. If that's the case, than you might be able to get away with honing that cylinder, but if any metal got through the pickup screen and filter and into your bearings, a full rebuild might be best because you'd have to pull the motor anyways. I'll try and find a minute to get up there. Keep me informed on what you find.

Re: Engine Clanking -WTF!!!
 

Before I saw the findings, I asked my uncle (the most mechanically capable person I know) how or why this would have happened, and he thought something foreign entered the cylinder, piston pushed it against a valve/hit spark plug, then the cam trying to open the stuck valve breaks rocker arm, etc. I wonder if something got in there?

I personally have honed/installed a new piston and ring set into a cylinder with three giant gouges in the thrust side of the wall, probably.050" deep, and the car had 155 compression in that cylinder and didnt use excessive oil.

Re: Engine Clanking -WTF!!!
 

I sprayed some brake cleaner on the walls real quick and got the walls pretty clean of oil. There are definatly little marks in there. I can feel them with my fingernail. I'm thinking nothing that couldn't get machined out though. But also not sure if a little hone dealy on a drill would get it out though. :(

Re: Engine Clanking -WTF!!!
 

Hmmm... you live in Shoreview right? You're not all that far from me. Maybe someday if you don't mind, you should stop out here for just a minute and see how my walls compare with the ones you did.

Re: Engine Clanking -WTF!!!
 

Your best bet is to run a hone through the cyllinder, then re check it. You could possibly get away with just throwing a new piston in that cyllinder (best case scenario) And as others have said, it's prettymuch guaranteed that there's metal shavings in your pan, so you can hope the oil pump didn't pick any of it up

Re: Engine Clanking -WTF!!!
 

I'll have to take a good look at the oil pan when I pull it off. I didn't think the oil looked too bad when I drained it out. Anything not perfect in it I was kind of blaming that on the old dirty drain pan that I used (should have cleaned it out before hand).

Is there anyway to pump a ton of oil through the motor to try and flush as much of that stuff out of there as possible before cranking her over?

Re: Engine Clanking -WTF!!!
 

Dam dude that sucks.

Spin the oil pump with a drill. But I would pull the pan and clean it first. Be sure to put something in place to catch the oil that would be going to the head. But you will still push some oil into the bearings as well.

You can get away with a fair amount on a motor. It may not be the best it can be, but running ok is better than in the garage broken. Be sure to have the rod checked as well.

Re: Engine Clanking -WTF!!!
 

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?

Re: Engine Clanking -WTF!!!
 

PMed.

Re: Engine Clanking -WTF!!!
 

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.

Re: Engine Clanking -WTF!!!
 

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.

Re: Engine Clanking -WTF!!!
 

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.
