ok now the story of how this all took place...

i took my car to a shop to have them replace my oil pan gastket, rod barings, clutch, and brakes. they pulled the engine to do the work. then when i got the car back, i started to drive away and when i got into boost (14psi) the intercooler pipes blew off. they were never tighened down. and they had re hooked up the vacume line to the KLR witch was disabled due to me haveing an after market boost controller with gauge. then we got the intercooler pipes back on tightend down i drove away thinking every thing was good. not 50miles later (the next day) i was leaving work and i stoped at the exit of the parking lot and my car died. i tried to restart the car with the clutch pedal in it sounded like it was seazed. since they did the clutch. let out the clutch pedal and the car started with a loud knocking and a bunch of white smoke out the taile pipe. not good. so i called a tow truck and had the car brought back to them. they pulled the enginge again and the head just to find this. now i have never heard of this before and i know the ammount of boos i am pushing should not cause this. is there something they could have done to cause this? messing up the rod barings? anything? what would even cause this? i have heard of the problem with bleeding the cooling system causeing head gaskets to blow but would that cause this instead of blowing the head gastket? my head gastket is not blown. i dont really have the money right now though i can get it to fix this. but should i have to pay for it or should they?

Were you drunk when you posted that?

It seems like a bad coincidence, honestly. I can't think of anything that would be directly connected to what they did that would cause your issue.

I may not know exactly what I'm talking about, but it really looks to me like something was in that cylinder bouncing around.
Is the turbo missing any blades or anything? The marks on the piston and the head... I personally don't see any way for that to happen without some kind of object in there.

This circled spot - it looks like the piston was squashed... how the hell do you do that?

myskyon · 04-04-2006, 05:18 AM

yeah it does looked squashed but all i can think of is that there was somthing in there. and i just found some info that the head gastket could have went then it caused a hydro lock condition wich caused the cracked cylnder wall.

Ouch! Have you looked at the bottom end yet? It does look like something got loose in there. However, the markings are more pronounced on both "high" spots on the piston, with corresponding marks on the head. Something loose would not have discriminated and would have more than likely made similar marks randomly across the piston and head.

I would think a valve would hit the piston before the piston would hit the head, but is there any chance a rod bearing would disintegrate and create this type of interference?

ilikemy944 · 04-04-2006, 04:45 PM

I see what you are saying, it does look like the piston may have hit the head. I don't know what the clearance is in there, but if you think a rod bearing could have done that, if the piston hit the head, it would have caused the head to lift, making it look like a busted head gasket...

Dunno... Let's see the bottom end?
I'm guessing it is at that shop still?

ilikemy944 · 04-04-2006, 06:53 PM

Someone on RL had an idea ;P
Lose end cap or broken rod bolt?
Shops fault?

There was something in the cylinder to cause that damage. The reason the damage is concentrated on the high spots is, because that is where the piston compressed whatever it was between it and the head, the rest of the combustion chamber was not close enough to crush it between them. When the engine was torn down something was dropped or left in the intake ports or intake system somewhere, either that or something came loose inside the intake system, possibly when the intercooler pipes came off something got into the intake system somewhere and caused that damage.

I for one would make them pay for all the damage even if something got in there when the pipes blew off, it's their fault they came off. Be sure to check the turbo for damage as it is possible, but not likely that whatever it was went through the turbo first. Also don't take no for an answer I don't know what shop and how honest they are but, they will probably tell you all kinds of stuff to get you off their back.

well the shop has desided to pay for a new engine they still dont know what happened. i asked about the bottom end and they said it was all fine. so i am guessing that they just dont want to admit they messed up and are going to pay for it. oh and the head was not removed the last time it went into the shop.

Glad that they are gonna take care of you

Those are some really ugly pics

WOW...... something got inhaled by that engine..............

Definitely check that turbo.

damn that is painful to see. if the foreign object (nut?) hasn't been located yet, you should definitely make sure it's found before everything is re-assembled.
