low oil pressure on start up
having rebuilt my engine and now done 1000 miles running in, when i first start engine it seem to take a while, on a second or two too build up oil pressure and i can hear it knocking for that 1 second, any ideas on what could be causing this please

Hmm. Shouldn't be knocking on start up, Could be draining down overnight. Needs checking out.
Loose oil pump screws/cover, dodgy pressere relief valve or the seal between the block and the oil pickup is sucking air.
Or there is a tolerance issue and its wiped out a bearing(s)

then all of a sudden. there was smoke every where
the pump screws on the back came undone, letting the oil every where.
worth checking mate.
has the car had low presure all the time, or just resently. since i changed to an uprated one. never had a problem.

due to the fact is was a little lower than my mates car
as soon as i changed to the new one, the presure was alot higher
and never had any issues since.
but i was just using this as an example.
this can/could have happened.
worth checking

think the noise still there only for a split second, if a bearing had gone it be there all the time, might just be me being paranoid. does anyone know of a good garage in south wales where i could have this checked plz
