Bent valves? or Droped a valve, Pictures inside!

[1999Gst]

So hey guys yesterday i was driveing my 1999 gst eclipse, just a 16g,fmic, 3inch exhaust. I turned a corner went to shift into second and it just died? Was running fine all day. Towed it home and pulled timeing cover and valve cover timeing was on, But ALL the rollers for the cam and spring were off on the exhaust side! They were just laying in the head! the intake side of the cams was perfect everything was good? Tryed putting rollers back on and only 3 of the 8 stayed on when i re did them and tighted down cam? what do you guys think happened? thanks hope i uploaded pics okay

Yes the belt may be in 1 piece, but I bet the timing marks will not line up. I would guess the balance shaft belt let the ghost out or the auto tensioner failed. If you turn the motor over my hand and look at the cam gears with both pins up and the timing marks pointing at each other in the middle of the cam gears you can look down at the crank pulley and the timing marks should line up with 0 on the front cover.

I had the teeth on the timing belt on my 90 laser sheer off on the crank gear. You could crank the motor over by hand but the cam gears would not move. But when I took off my Valve cover it looked just like that.

So its at least some timing belt or tensior failure.

I think you hit it dead on, before i pulled valve cover i tryed turning it over compression was 0 and seen strings in the timeing cover, so if i redo the timeing and "say" my head is good, hould i be able to salvage the block even tho balance shaft belt broke?

Yes the short block will be ok with a timing belt skipping or breaking. The pistons will have some marks but you just need to rebuild the head, or buy a used one and bolt it back together.

A question of the ages. Many people say OEM is the way to go, some say MLS. I liked MLS myself, but have used OEM before.
Studs, get ARP L19s.
Just make sure you do your research prior to going down the hp goal road. While some guys make it look easy, it takes time, effort and Money. You cant spell Research without SEARCH. Search the site as there are many builds out there people have had great success with, that would get you around your goal.

Ok thanks, what should i do about the balance shaft? Is it that hard to delete them while motor is in car or should i pull it to pop those bearings out. My buddy has a 6 bolt that crank walked and it has the elimination kit on it. Could i use his kit or should i buy a new one?

All right head off! EVERY VALVE BENT! 6 BOLT TIME ! lol or should i get a head and say fuck it?
