Nooooooooo

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

im assuming the shells will be in pieces but we,l see !

top big end will be worst and lower main

hi guys
The sumps off as is the oil pump / strainer but i cant seem to remove the ladder frame i can get a scraper between the surfaces and have removed all the bolts that appear to hold it -
Is there something im missing ??????
any advice greatly appreciated as bottom ends are all new to me !!!
cheers for reading

its bolted through fly wheel housing

cheers james - does that mean the gearbox has to come off ???

just the four lower box bolts iirc defenders do have to have box out as they are allen bolts in flywheel housing but is along time since i did one in vehicle

Nice one james - was panicking a bit there, thanks mate

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

have you checked valves are all opening equally ,push rods can punch through follower ,valve caps disintergrate

They all appear to be doing as they should - would that show up if i measure the clearances james ?

Could it no be a broken injector of something ?

id check them sounds like its blowing into manifold ,valves that is

check the injectors ???

He meant check the clearances

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 ?

ah right cheers

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
