i proceeded to go wow, i have never seen that before, showed all my roomates, then proceeded to do a compression check. by the way the bad plugs were pulled from #2, and #6 the worst plug was #6. i did a compression check and #1-#4 were runnin between 151-152 psi, #5 at 124, and #6 at 0. what are all the possibilites of these numbers, bent valve-broken rod cap. what steps should i take next. and how i should brake the bad news to the patients owner?
your help ismuch appreciated

pull the head and see what ya got

is this a fj cruiser,  2F 

ouch, looks like an expensive little problem he's got there.

What did the top of the piston look like?

My stud broke off once and went down there, luckily I think it blew right through. 

i would look the valve over good,  if its not marked or the seat,  remove the bolt and slap it back together with a cleaning first and a new gasket,  the valve seat and valve should be harder than the bolt

yep,  shavings a bad

i just meant he shouldnt need a valve job if the valve isnt damaged,  but if those are metal shavings   flush the engine out with some kerosene

ive got a buddy that works at a local machine shop around here and im getting the whole head rebuilt for $100 including parts, but ya i was definetely going to flush it out but never thought about kerosine, good idea. all in all its costing about $625 because of one bolt that was dropped down the carb. ouch, good thing its not mine.
