how much of the stem is still attached to the valve?

my guess  is that whatever came in your intake got caught in the valve, hanging it open.
then when the piston came up, it smashed it breaking the stem and dropping the head of the valve into the cylinder.

would be interesting to know ow far up the stem it broke though.

sorry to hear about this, it always seems to happen just after they get back on the road too...

I'm pretty sure thats what happend. Most of the valve stem is there. The valve head is obviously stuck in the piston.

I don't feel like a guinea pig. I wanted to post these to "inform you" give you something to see. Pretty sure something was in the intercooler and it was blown into the engine at high rpm and hung the exhaust valve.

It died quick and i pushed in the clutch as soon as it nosed over. You have no time when the piston is traveling that fast.

my bet is a cracked lifter that turned sideways in the bore holding the valve open. ive seen there engines eat exhaust valves a hundred times before, just never on any of my engines. my 1.5 had that same thing happen. put a used piston and rod in it and its still goin strong.

[foxracer1]

Lifters were all fine. The piece i found in the exhaust manifold is unknown. Its not from any internal engine parts.

how bout your compressor wheel, hows it look?

[foxracer1]

Haven't taken the turbo apart yet. Turbine looks to have suffered some minor damage. Probably still runable.

Is the material in exhaust manifold, is it alluminum or steel?
Lets do some detective work.

My guess right now is thatttttttt it is...

a piece of casting from the IC that never got removed/broke off or something...

When i first pulled my new head out of the box it had some casting flaps i had to dremel off. Would have yielded similar results im sure had that piece tried to go through a valve.

Bloody Ouch!

[foxracer1]

Yes aluminum. I too think it must have come from the damn intercooler. Never heard anything in it must have came loose from driving.

Gonna mount a garbage disposal just before the intake to mulch anything into smaller edible bits for the engine

[truckinwagen]

where did you get the intercooler from?
what brand is it?

that sucks big time...

is the stem of the valve poking out the bottom of the piston?

Bought the IC from a member on here used not sure of the brand. There wasn't much stem on the valve but you can see on the bottom of the piston it cracked it.

I may try to find a way to install some screen to catch any loose *** before it gets to the engine. As long as it its self doesn't become loose and cause probs.

my audi has/had a chrome steel grate in the intake pipe. it looks stock also. but it would still let the compressor get whammied pretty easy.

fek me!

fek me!

How's the bottom end look? Sorry to hear about this

[foxracer1]

Crank other 3 pistons and rods are ok but theres a nick in the cylinder wall and its already 1mm over so not sure if it 'll clean up enough to be reusable?

I'd probably buy one piston a rod and lightly hone the cylinder and run it in a low performance application. stock boost and such. Guess you could always sleeve it if needed.

BROKEN!!!!
