Think the bloke who had it before has messed around with it not put pipe bk on properly surely the hole in pipe will muck it up as air getting in where it should not be u can see hole in pic if u zoom in
your unlikley to get air intot eh oil line, runs at pretty high pressure. get it sorted asap so the pipe doesn't fail.
might be worth get the pipework checked over by a specialist then getting it on the dyno to make sure all ok, better to check and be ok, than not check and be an issue
