Wash the engine regularly! ....... using "Vanish"

IT IS NOT FUNNY!

Peja

Well, basically, since thay have applied some sort of sealant at the service, you cannot know if it's effective (distinguish new spots from old ones) unless you have cleaned the previous spots thoroughly.

Which service have you been to? You can reply in a personal message if you don't want to anounce it in public.

This looks like a defect Cylinder head gasket (nothing to take lightly )
get it checked you can have it checked by Dacia and TELL them what I have just said and also look here

Stu,

thnak God, but this is not my case.

This topic is well processed at romaian part of forum, but google translator is very poor (romanian -> english), so I didn't undertod all posts.

Stu, I never heard nor read on this forum of such a harsh break-down on a Logan engine.

Unfortunately Peja and his friend have engines from a bad lot, and these engines have oil leakages - mine had it too.

The cause can be either two insufficient sealed screws or the item in this picture: http://www.daciaclub.ro/index.php?showtopi...ndpost&p=821674 - I don't know the English term for it.

On the Romanian topic on this issue we are wondering why Dacia / Renault are insisting putting these low-quality items, even knowing that they will have to be replaced trough warranty.

Sealing those screws is the first attempt to stop the leaking, that's the operation Peja has already done. If the leaking continues, they have to replace that item I've showed above. That's a more complicated operation, it takes a long time (a few hours), and I recommend the owner not to look if he has a weak heart , because a lot of the underside of the engine will be taken apart. At the end, the engine has to get a new timing belt (it is not allowed to put the old one back), and also the alignment of the steering weels has to be verified and/or corrected. All these on the factory expenses.

Paul,

If I read well on ropamnian part of forum, it is not recomanded to seal those screws. Why? Is something bad to happen, or problrm will be masked?

I don't recall to read such a thing. When I will have a little time I will re-read the whole topic. But IMHO it can't do any harm, at the end it's a simple industrial sealant, with no chemical or mechanical side effects.

The main question is:

why is oil leaking at screw?

Is it screw defective?

Is there undesired oil presure inside engine?

What?



Peja

BECAUSE THE GASKET ROUND THE BLOODY SCREW IS BROKEN
BELIEVE ME !!!!!! OR DO YOU REALY THINK THAT YOU HAVE TOO MUCH PRESSURE IN THE ENGINE AND IT IS ACTING AS A BLOW OFF VALVE!!!!
THE SCREW SCREWS THE HEAD ON AND GOES INTO THE HEAD NOT INSIDE THE ENGINE IT KEEPS THE CYLINDER HEAD AND THE MAIN ENGINE BODY SECURLY JOINED
STu

The main question is:

Is it screw defective?

Is there undesired oil presure inside engine?

Because sealing was not done well. No, no undesired oil pressure. But, IMHO, only 10% leaking occurs at those screws.

BECAUSE THE GASKET ROUND THE BLOODY SCREW IS BROKEN
BELIEVE ME !!!!!!

Dear, you've got an obsession! You have no ideea what screws we are talking about. They have nothing to do with the gasket. My car has underdone both operations and I can assure you that work is done only on the lower half of the engine (not even the air filter was taken off), both for the screws and for the defective "Antriebszahnrad".

And please do not further yell (=CAPS) at us.

Screws dont leak my friend they hold two joints together! A plug could leak .but only a gasket under the plate that a screw is holding together can leak
.And if you dont like me shouting dont wind me up and why bother to tell me (an Englishman) that its a Antriebszahnrad we call them drive wheels
Have a nice xmas and get someone to buy you a good Car repair manual
Stu

Ok, Stu. You are smarter. You are right. You have a better repair manual than the original one. You have seen the gasket leaking with your own eyes.

Pleased now?

I'm tired arguing with smart people from Duisburg and Englishmens from Waldbronn. I was just trying to help, even with my little knowledge of mechanics and English.

Have a nice Christmas, too!

PS: By the way: did you look for oil spots on your engine?

I was looking at some technical manuals that I have, but I couldnt find exact construction of screw, distancer, shelf...

Maby the paoblem is caused of distancer. There are 3 problematic joins. Motor-distancer, distancer-shelf, shelf-screw head.

Pretty stupid solution from Renault.

Two years ago I paid 1000 euros for a new cylinder head gasket a new belt new oil and flushing of the engine this was all in a YES RENAULT TWINGO and it was leaking exactly in the same place
I come from Grimsby UK
Stu

OIL AGAIN! After 400km from "sealing grease" service. It was a good try!

hello Peja. i will try to explain to you what the problem is from what i found out from the romanian pages of this topic. in service they use silicon on those screws because they hope the leaking will stop but that is not the case. the oil comes from the round gasked between the engine block and the distribution shaft (it is called simering in romanian) and this will be replaced in your engine if u go to service again, but the problem will not be solved because the root of the problem is in the engine block in the lower half. the faulty piece is on the same shaft behind the "simering" and it`s made in romania. i think it`s called a cog (a wheel with teeth, pinion in romanian) that destroys in time the simering. the oil is present everywhere in the area (you can see it if you remove the plastic cover of the distribution).
fot the mechanics to replace that cog (pinion) they have to unmount the "oil bath" and for that they have to lift the engine. if they say that they have replaced it you must see on the bill the "oil bath" gasket and they have to realign the front wheels (direction). if they don`t include those operations it means that they`ve changed only the "simering". that is the case in romania...they hope that only replacing the gasket the leaking will stop, but it doesn`t. one user of this forum had 5 interventions in that area until they replaced that cog with one made by renault and only then the problem was solved.
sorry for the bad english but i don`t know the terms for those parts. i hope this information will be usefull to you.
good luck in solving the problem!

Psychoo:

If I understand this is a problem.
The problem is solved by replacing the two parts .
1.
http://en.wikipedia.org/wiki/File:Chain.gif

2.Simering in romanian, semering in serbian, oil seal in english

My Logan in 2005 and not this problem. Why?

Psychoo.

thanks for explaining, but as I've understand, it is triple problem:
1. screws
2. pinion
3.semering

Bad pinion destroy semering = oil leakage.

Why then sealing screws?

Correct?

Sealing screws is least expensive, for one thing (when it goes at the expense of the manufacturer)

Hopefully, the leakage would stay contained behind that cover, so you wouldn't be aware of it and you wouldn't even know how they screwed up! But they screwed up even that plan

Please, speak your vision of the problems in our forum http://daciafanclub.6.forumer.com/viewtopi...r=asc&start=120

i don`t think that the oil leackage is coming from those screws. oil goes everywhere. i believe the oil is thrown all over the place because of the rotating shaft.
i am no mechanic and my advice comes from what i`ve read on the romanian forum in the similar topic.
in romania they have specific operations for each problem and they start with the easy solutions and if those backfire they`ll dissasemble the engine. of course some mechanics know about the faulty pinion (sprocket ). some are lazy and want to screw the client and only a few (if you`re lucky to find them) are fixing the problem.
best regards

So sealing screws only mask problem hmmm

but it can not hide this:
img1063yp6.th.jpg

Oil is everywhere on chasis!

Dissaponted with DACIA-Renault!

Peja

welcome to the club i think all the Dacia owners are dissapointed with the manufacturing company for some reason but we wanted cheap cars. cheap and good quality don`t usually mix
after you change that faulty sprocket and oil seal (semering) the leaking will stop, just make sure the sprocket is made by renault france and not romania. basicly all the renault clio engines 1.4 K7J use the same sprocket (maybe even 1.6 mpi???) so you can purchase the part for renault clio if you don`t find it for Dacia.
good luck
