poss oil pick up blocked??

[Charlotted]

I went to change the gear box oil today and engine oil and found i didnt have a tool for the gera box. Changed the oil in the engine and filter and engine still runs rough for about 5minutes and then runs ok. Is there any problems with the oil pick up on the cars?
I am also having problems with gear box bearing being noisy and as i said above was going to change the oil but i have been told that i never need to change it only top it up? is this true or should just change it all?

I've not heard of a problem with oil pick up before. However I do know that pattern oil filters have been known to collapse and cause problems and so I always source my oil filter from the Peugeot main dealer.

Earlier Peugeot engines used to suffer from premature camshaft wear because of problems with the oil feed to the camshaft. I suppose that if services have been overlooked, and oil and filter changes neglected, then that problem could arise. With oil and filter changes scheduled for every 20,000 miles or 2 years I suppose it easy for some owners to forget it needs doing. Being "old school" I am a firm believer in an oil and filter change every 10,000 miles or annually. I always use Total Quartz 9000 5w40 Fully Synthetic oil too.

As for your gearbox, the reason I suggested renewing the oil was in case your input shaft bearings have worn to the extent that they have deposited swarf in the transmission oil which, in itself, can cause more wear as the swarf is carried about. Refilling the gearbox isn't an easy job, and is time-consuming but is easier than stripping and reconditioning the gearbox. I'm pretty sure that changing the transmission oil is not a scheduled service item. Normally one would check and top up as necessary every 4 years or so.

Thats great help mate.
Just been out in the car with the wife driving it, and pin pointed when she accelarated the whirling noise gets louder and faster, the faster she gets. its doing my head in.

Does it stop if she dips the clutch while moving along at speed?

Regarding rough running, the oil pickup pipe in the sump has a gause screen on it that can get sludged up in extreme cases of bad maintenance / cheap oil, but is fairly rare.
I have seen the sumps on some cars dented upwards (due to running over something) and this can effectively block off the oil pick up.
A quick look underneath would confirm this.
In any case, poor oil pickup for whatever reason doesn't generally clear after 5mins and you would hear a loud, harsh knocking from bottom of engine.
Are you sure it isn't a missfire? What spark plugs? Worth trying Bosch super 4's if not fitted and NGK plugs can cause problems.
Gearbox probs already covered????

GrandadMonkey- yes it stops but is it because i have dipped the clutch or because i have stopped reving it???

Capncol- i say it might be the pick up because i an a vw man at heart and had to prove to vw that it was a problem with here cars when they told me it wasnt and just wondered if it was the same problem?
when i start the car the warning light stays on for a few seconds making me think oil pressure and the pick up

As it is engine speed related rather than road speed related it seems to confirm Capricol's diagnosis: worn input shaft bearings.

I suspect that the noise will disappear when the clutch is dipped while the car is moving at speed, even if the engine revs are kept up by maintaining pressure on the accelerator pedal.

Be careful if you try this - we don't want you having an accident.

So does engine sound harsh? Oil light should go out almost immediately.
Still unlikely to be pickup (unless it is sucking air) Have you got the correct grade of oil, filled to max mark on stick? What make of filter? Lack of oil pressure at start up can also be caused by oil pressure relief valve not seating properly (in pump) among other things.
I have just rebuilt a Lambo gearbox while a mate of mine did the engine. It was suffering from oil light on at. start up accompanied by harsh engine noise (intermittanly) Turned out to be broken spring in oil pressure relief valve.

You can prove if pickup is sucking air by disconnecting coil pack seeing how long oil light takes to go out by cranking alone, then temp overfilling sump by about 3" on dipstick, then crank engine again to see if oil light goes out straight away or quicker than with normal level. Disconnect coil pack as it is not good to start or run engine with that much oil in.
By overfilling by 3" you are taking the oil level above the pick-up, so if there was an air leak it would suck oil through the gap if you know what I mean.
Return oil to correct level before attempting to start.

As it is engine speed related rather than road speed related it seems to confirm Capricol's diagnosis: worn input shaft bearings.

I suspect that the noise will disappear when the clutch is dipped while the car is moving at speed, even if the engine revs are kept up by maintaining pressure on the accelerator pedal.

Need to shift to neutral too otherwise 1st motion shaft will still be turning at road speed due to the gears still being in mesh

Thanks again to the both of you. Now I need to find the bearings so I can have it fixed.
