Need to replace the oil sump as it has developed a leak due to corrosion.

In 46 years of owning cars some a lot older than my 9 year old Fabia never had a corroded sump. Would of thought that Skoda would have by now used a plastic one.

Where abouts is it leaking from? Has it developed a hole or is it around the sealing face?

 

Presume we are talking pressed steel sump here?

Lucky one owning cars for 46 years and only bumping into this now, my first experience was back in 1994, a MK3 Fiesta and my wife's first one with the grey painted engine and so sump, I had not expected that so didn't look for or ignored surface rusting, that cost a new sump which I wiped over with meths to de-grease it prior to covering with a complete small tin of Hammerite - wiping it was meths removed all the original paint! All her and my cars since then have had alloy sumps, well maybe except my B8 S4 which has a steel plate closing off the bottom end, and I keep a check on that even though it is covered up from road grit etc. My daughter's late 2009 Ibiza 1.4 16V 86PS needs a quick rough rub over and repainting with black Hammerite every year at service time.

 

Plenty other marques have or have had this problem, VX for one in Astra etc, plastic sumps, or metal sumps covered in plastic, Pug did that many years ago on their derv engines, now what happened to some people was, stone chips or other debris chipped through the plastic covering, water got in and in worst case the car survived with this undetected until it touched a speed bump and that was enough to break free the now only plastic sump base - not good!

I'd think that it is at the RHS lower edges and RHS end (side) surface as that is the area mainly exposed to the worst of road debris attack - and yes pressed steel sump.

 

Edit:- really just unattended to surface rust gone mad, when I removed the just very slightly weeping sump from my wife's Fiesta, the inner surface had many  blue/grey/black area from imminent "through rusting" instead of being silver clean steel!

Quite surprised it has a steel sump TBH, the diesels have had alloy sumps for nearly 20 years,

 

Also, no undertray?

The Pug derv engine was in a Sierra - and it ended up being well chipped form all accounts, I don't know Sierras at all so probably no full engine cover, from knowing the guy that owned it, he did like to play with old tractors - and still does, but does it with a Toyota van now!

 

It was really only me telling him about my wife's MK3 Fiesta sump weeping that prompted him to complain about the set up on his Sierra with the Pug sourced derv engine. I think that more than a few TX* taxis also suffered from that illness with that Pug sourced engine.

 

Edit:- the joke was, if you went to a scrappy's and managed to buy a sump from an older Ford engine that was sent out from the factory painted black, it would be in perfect condition - but as you might imagine, not many scrap yards would allow you to remove the sump so that supply for owners of Ford 1.1 OHV engines that left the factory painted grey soon dried up.

Yes it's a pressed steel hence comment why it's not plastic,  yes its weeping oil from the the RHS side.

Must be built in osolescense , could hade thicker grade of steel instead of cheaper thin steel grade. Should really last more than 9 years.

Car has small tray from bumper to cover gap between radiator and engine. Not a full tray as on other cars. Should accept Fabia are made to cost to make best profit.

As want to keep for more than another 9 years

 

 Going to buy one of these

Do you really want/need to buy a heavy steel under shield, that is to protect the sump etc from impact from rough terrain, maybe look and see if any other Fabia/Polo use a plastic full under tray - now that you have mentioned this, I don't even know what is fitted to my wife's 2015 Polo 1.2TSI 110PS !

 

I know my older daughter's late 2009 Ibiza 1.4 16V 86PS SC only has a short plastic front section - and so needs the sump "refurbished" at service time!

As I said have small tray from bumper to engine.

When get new sump will probably paint with hammerite.

You say that like they are the only materials a sump can be made out of.

Yes there other corrosion resistant material like Alloy (like as said on Diesel engines) ,Stainless steel , Titanium , Composites (using carbon (would require glass fibre surface ply to eliminate galvanic corrosion), Glass or Kevlar fibre) , Vacuum forming Thermoplastic or Coatingsplating such galvanising, zinc, chrome. 

Some of which would out last the life of the car.

And would add to the cost,  the Fabia is not a premium vehicle like the Octavia, Superb along with numerous other marks.

For instance I have replaced all the suspension rubber bushes with polyurethane polyflex ones and will outlast the car. Which are more expensive than rubber ones BUT car manufacturers won't fit as standard because of the cost believing that would result in cars lasting longer and mean less sales.

Fit new sump, check for surface corrosion once a year, clean up and repaint if any is found, problem solved.

You forgot aluminium alloy as a common sump material, arguably the best.

Morning Thanks will paint, Just updated to add Alloy

Its funny because under try's protect from small impact but also partially prevent the usual build up of oil residue which will actually help prevent external rust to some extent! The sump should not rust internally as it is an oil bath so well protected but externally, if smattered in oil, grease, etc, should remain rust free for ages!

 

Only sump issue I have ever had was when I had a lowered vehicle (MG Montego Turbo) which I was driving along  a road that was being re-surfaced and the raised ironworks scraped a split in the sump, right where the oil filler screw went, making it too tricky to repair but a local breakers yard had the correct part which I fitted with fair ease.

Just to say that our 2009 htp fabia sump was also badly rusted mainly on the front face.  Looked like a combination of hits from road debris, stones etc and compounded by salt acquired during winter months.

 

Fortunately caught it a couple of years ago at 55,000 miles. Never noticed in any of the previous years so maybe it was a particularly bad winter. My daughter did have it for over a year in Scotland, may be the reason.

 

Rubbed rust spots etc down to metal with 80 grit aluminium oxide paper, and steel wool, then a spray over with cold galvanizing spray.

 

First time ever seen this amount of sump corrosion in 45 years of DIY servicing/maintenance on numerous cars.
