307 67k low oil pressure

[peugullist307]

Hi, im a newbie, so thanks 4 having me. Prob is, bought this car with 67k, on a 54, did full service, flushed engine before oil replacement, (bit sludgy), filters, the lot, even changed the oil pressure switch, but only just located the oil sensor, hard to get to, so dirty! Low oil pressure still showing though. No oil leaks and runs well enuff. No other noises or thumps. Timing belt not been done dont think, so may need replace that, prob water pump too I guess. If i changed oil pump (big job?) would that maybe solve it? Dont want to spend fortune on it as I got it as a bargain £3k but realise it may take a bit of work. Cant do it myself so have to get it to a local mechanic and pretty skint as it (like everyone else, thanks Mr Brown!). Any advise would be extremely greatfully recieved! Cheers guys.

You don't say what engine you have? What make oil filter did you use? Stick to genuine pug, or one of the OE manufacturers such as Purflux or MAHLE. Some of the cheaper brands are notorious for oil pressure problems. Then there's the switch itself, though you say you've replaced that. Then there's the pump, but if that'd been U/S for long the damage would be done and it would already have a rattly top end. What device are you using to determine an oil pressure problem?

have you actually had the oil presure measured??

HI, you could have a faulty oil pressure switch, you need to screw in an oil pressure gauge in place of the switch to check pressure, if you can see loads of oil in the rocker cover with engine running, and engine has no excess noise you most likely have good oil pressure, or your oil pressure relief valve is gummed up with sludge, and some engine flush may help, i did once have a pug with a broken oil pressure relief spring, this was in the filter housing, this is rare, so check pressure with gauge first to avoid any un neccessary repairs, best of luck to you.
