View Full Version : help - what is this noise
i got my car back last week but every morning when i 1st start it it sounds like summat is trying to jump out of the engine :shock: my heart is in my mouth each time
i have took it back to ltr and let it cool down before i started it but no noises so they didnt know
im guessing whatever it is banging about had a coat of oil while running but over night it loses the coating
what could it be
now iv got it recorded ill go back to ltr 2 see what they think it is
between 10 n 20 secs

sounds like a milk cart went past, like bottles rattling :?
sometimes when i start mine i get tappety noise, but lasts literally seconds
it had cambelt / cluth oil/air filters n dogmount / water pump
the rocker cover was took off to inspect engine
it fades out after 10 secs and then for rest of the day but it dont sound healthy :(
what do u mean hows the timing ?
it runs ok would it run shat if it was out
id of thought id hear spluttering or summat
will seem to lack power, but symptoms can vary
its a 2 min thing to check with a strob gun
I was speaking to James this afternoon. Hooli, it sounds like piston slap to me, which is usually signs of the bottom end on the way out.
Leave it until a morning and do a compression test when firing it up, then do one later on when it is warm, see if that gives any differences
its hard to tell but it does seem a little down on power
ill go back hopefully they might check it to eliminate that
sounds a bit like the bottom end starting to die :?
it sounds like top when i start it
never heard it do it before
could it be down to shite oil coz the presure gage went highest iv ever seen it till it warmed up
what is a good oil that coates stuff over night :)
something ester based gives parts a coating of oil, such as Silkolene Pro S, or Motul 300V
top end could be a noisy tappet. but piston slap sounds top end.
but piston slap sounds top end.
It does indeed, it's when it is wobbling at the top of the bore
Could be pinking noise. Try a higher grade fuel and see if it goes away.

Pinking is usually only under load.
I'm putting my money on piston slap. Not that I want it to be bad news or anything dude, it's just got all the hall marks.
