I had some days off this week and finally went and picked up my brothers' engine hoist. When I got it back I got it on the stand and started tearing shit apart.
Prepare for carnage!!
Getting the engine from hoist to stand. Didn't really plan this pic at all, and didn't notice till I got some funny faceboook comments. haha 4g63 Allis!
Got the intake manifold off and found this...Where is the rest of the valve? You can just faintly see the cracked valve guide as well. Phone didn't want to focus very well down the runner like that.
Got the junk ass crank pulley and water pump pulley off along with the timing cover. The water pump bolts were just a tiny bit more than finger tight. I'm not sure that has anything to do with the failure though. The timing belt was loose as hell too.
Ahh! There's the problem! Think it'll buff out?

So the head is junk, I figured it would be, so that is not a surprise at all which is why I picked up the 2g head last summer.
On the the pistons.
#1:
Nice pile of aluminum shavings there, my guess is that happened when I was turning it over and over while trying to get it running before I discovered the beat up spark plug. What's weird is that the engine didn't make any noises until I cranked it probably 15 times and I stopped and checked the plugs.
