FS: Porsche 944 straight through flow short cylinder head valve & piston combination. Free shipping lol. First time i see a embedded valve into a piston
the valve broke off from the stem

Interesting. I wonder how that happened. That is exhaust valve?

Must have had some piston to valve clash through broken timing belt and then just rattled around inside the combustion chamber until it finished where it is. Would have made some interesting sounds!

Something like first 30 seconds of this song

I've seen this before on an early car. Mechanical overrev. Pretty good carnage photo though.

I had a Focus with a high comp 2.3L motor swap, had some bad engine work done by a local shop and the valve clearance was never checked, ended up embedding a valve just like that, the stem also punctured several holes through the piston - didn't crack the piston though! I'm a sucker for stuff like that, it's going on a shelf in the garage as a display piece someday.... a reminder to just do things myself.

This came from a 87 944S what makes this rare is the fact that this was a single valve that probably got stuck in the guide hit the piston broke off from the stem and got embedded to the piston. Nothing else got damaged no other valve hit the Pistons the chain tensioner and cam teeth were intact.
