Engine Clanking -WTF!!!

[Goat Blower]

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

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 :(

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.

^oooh, good idea.

[Halon]

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...

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.

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

[turbotalon1g]

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

[Halon]

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?

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.
