Most Colossal Screw Up Since My Last One

[iamtheosprey]

Ok...So I finally got up the gumption to change the head gasket on my 1984 190D.

I got it all torn apart, cleaned the mating surfaces and put the new gasket on.

In the process of cleaning the mating surface on the block I decided that I should rotate the engine a bit so the pistons were all recessed.

I did this.

This may have been the fatal error but I surely complicated it afterward.

I didn't turn the engine back to TDC before installing the head.

I realized after the fact that I should probably do that.

The cam isn't on the car and obviously the timing chain is just own in the crank somewhere as well.

Since I got the head bolted down there was nowhere for the compression to go as I rotated it and the chain was binding and even sounded like I head a nasty metal on metal sound in the process.

Would I be right to assume this engine/injection pump is toast?
