you should know then state off shells can be somewhat guarrenteed by checking oil pressure speed of rise as well as pressure using temp to ,and that rocker removal wasnt necessary

Well it wasent the big end shells as ive just completed the task & it sounds no better !!
im guessing a cracked piston or dropped valve, couple of questions ???
1. whats the chance (if a valve has dropped) of the piston being ok ??
2. if the piston is cracked could it just be replaced ??
3. i guess its becoming obvious that i dont want to buy a new engine !
I would rather put a head on it if poss as its now got nice new big end bearings !
please someone say theres some light at the end of this extremely dark tunnel

sounds a lot more terminal than an injector, how would an injector make it sound that ill ?
im not arguing just want to know how it would cause that ?

TBH im not surprised its not sorted it as i thought from the beginning it sounded valve related but my mechanic friend assured me it was big ends !
Its hard to tell with recorded sound you should maybe just wip the head off and have a good look

first time ive heard video ,but noise doesnt sound engine speed as you get with journals more 1/2 like valve train ,gasket blowing to outside,valve bent and sometimes just split in exhaust gasket
