Hi folks,

I recently bought a Renault Scenic 1.5 dci 2007 with 86bhp and I'm about to change the oil and filter, but can't figure out which filter is the correct one. I can see there is a very small one with around 50mm height and another with 64mm. I noticed that bypass valves are set with different pressures for each one of them, so, I don't really want to fit an incorrect filter, that might damage the engine internals. Need some help guys, please.
Thanks.

hi
assuming your UK located ? try the ECP web site insert your car reg no and it will advise you correct filter & price etc.

Metal filters have one inside at the top DD,

If the oi lfilter becomes clogged, ( normally forces the oil filter out of shape first .Not come across one happen for a fair few years.)
then oil will by pass the filter
Datsun , was the last one, before it became Nissan.
Long time ago:grin2:

Thanks for both replies. I'm uk based and tried ECP site, and it shows both filters.
For example, MANN filters gives the w75/3 and w79 for the same engine, but seems like they operate at different pressures.
My car at the moment has the 50mm one, but I just want to be sure if the small filter is the correct one, since I'm about to change the oil for the first time.
Engine has a quite loud ticking noise, more evident when is cold... injector seals are Ok, so want to change the oil, to see if it gets any better.
Thanks.

Not so long ago, mentioning the paper filter..
Vauxhall car, someone did oil and filter change. But the paper element collapsed and was shredded , he managed to throw the pressure relief valve away with it.
Once filled with oil, no pressure, oil light on.
One sump removal, and cleaning of pickup.
Was called to have a look.
Took some working out, with the oil switch out, it just about dribbled from the orifice ....
This part, came complete with the housing.....
Found a local breakers and took it out, replaced all good.....

Right then, back to OP's question.

The filter bypass should only open when the filter has become so clogged that the pressure drop across it starts to significantly restrict flow.
Works on the principle that dirty oil is better then no oil.

In normal use and service intervals, this point should not be reached so the valve pressure is irrelevant.
If different between makes, I suspect has far more to do with filter mechanics then engine need.

On my Scenic, filter bypass is shown as 1.5bar on all filters shown by ECP
But are all same size with Height of 80
On my Kia, none show a pressure value
On the Q car, no filters are shown :(

Hi,

First of all, much appreciated for the replies, it's been a while since I've seen so many people trying to help in a forum. Congrats to all. :grin:

Service is now completed. The oilfilter supplied by the store was the smaller one, and everything seems fine. Changing the oil on these engines is so easy... however, the air filter is a bit fiddly to put back on, but its doable with a bit of patience. The fuel filter needs some good hands/fingers to disconnect the hoses.
Anyway, service this car is something that anyone can do.
Unfortunately the ticking noise is still there, can it be related to the gearbox? When it's standing still, with no gear engaged, whilst revving it, I almost don't hear it, meanwhile, on the road, it's quite loud, specially when cold...seems to get less evident when engine is warm.
Any ideas what it might be?

Many thanks.

when the car is cold preferably in the morning.
Lift your bonnet, start the car...
See if it is coming from the top of the engine, under the rocker box cover..
These are shimmed tappets and wear, but because metal expands when warm, the noise is not as bad.

If its the tappets, maybe in 50,000 miles time.
One of my customers his modus when he had it 5 years ago, had this, he is still driving it, 20,000 miles later, ...
He knows its there, but he has learned to ignore it,, bit like living by the railway track, at first hear every train, then dont notice..
 
#18 ·
I see what u mean... I try to ignore it too :grin: what can fail if I leave it like this? The noise will only increase, until one day.... ??
Can the engine fail? If the valves gaps are checked, would this help? Maybe thicker oil? I've just changed it with 5w40 shell, that meets Renault spec. Would a 10w40 be of any use?
Thanks.
 
#19 ·
Nothing can fail,, as such, the shims will wear, as will the cam lobes.
He has always used 10w 40, but his is changed every 12months, without fail.
He is 70, and does his own oil service I do everything else......
Its only done 64,000 miles.
Two owners from new, his brothers, and his.
Full service History and some, from Renault main agents before his brother gave it him.
But they were not concerned,,, and it was an open check book when his brother owned it.
Only size car that will go through his brothers top gates at his house.
But his brother loves Renault, and every 7 years his brother gives him the car.
(Lucky barsteward)
No idea what he will turn up in, in 2 years time, but it will be A Renault.

Ticking tappets can go on forever.
Personally I would not use a thicker oil either.
May reduce noise there but reduce oil flow elsewhere that needs it.
Not so long ago we had a guy querying turbo oil feed pressure. His was low.
Oil used was a 10w40 IIRC instead of the recommended 5w40.
Swapped to the 5w and pressure got to where it should be.

Had a clio with ticking tappets ..done about 25k miles with it before selling it to a work colleague ...6 years later he is still running it ..he only uses it to go back n forth to work

Thanks for the replies. I'll just leave the 5w40 and learn to live with the ticking when cold. Get the radio volume up :grin: ...nice trip yesterday from Aberdeen to Edinburgh, managed 51mpg. Mpg is worse doing 65, than 70ish...funny! Better mpg is when doing 55/60mph... but it's too slow... I'll go with the 70ish...

On these cold mornings the tappeting noise was pretty evident, so I decided to swap the oil to motul 10w40 renault spec also. The noise reduced considerably, and yesterday received a tuning box, I've set it to around half of the power range, the noise is even lower now... and the car is a lot more pleasant to drive now. 85bhp on a scenic is pretty dreadful... as you can imagine.

The box was 2nd hand, but they cost around £80. Let's how's the economy during next weeks...

Yes it is, But Not always about pressure. Often Flow is as important, to shift heat away, for instance.
