engine knocking diagnosis

[lewis_willy2]

occurs between 3000-5000rpm, starts quielty but gets really loud. its quite a dull knocking. on idle and under 2000rpm there is no noise.

it still runs fine and still seems to pull just like it did with no knocking. not lacking in power.

its just as loud knocking when under the car near the sump as it is wen you listen above the rocker cover.

also the starter really struggles to turn the engine to start it.

oh and it was v.low on oil.



my friends dad has suggested cam or tappets. but its seriously loud

i think its poss spun a bearing? im not great at diagnosing faults! so any suggestions would be appreciated.

sounds like youve fecked the bottom end.

[lewis_willy2]

its my m8s valver, i reckon the bottom end is ****ed and the starter is struggling because the bottom end is real stiff

[Coops]

ai sounds like spun bearing mate, or at least excessively worn and low oil points to that aswell as they wont recover like tappets when the oils refilled

oh and dont do that, i thought u had the tubby runnin and had fubared it........ :shock: :wink:

oh ye should have put at the beggining it werent mine. ive got this to fix now. my m8s just cracked his gearbox so gotta replace that. engine and dash loom in a 1.4/16v hybrid to replace and the williams to get sorted. there never enough time and they've all gone wrong at once!!!!

any more suggestions as ive just bet my left bollock with my m8 its the bottom end!!??
