Euroserves help required New Oil sump ?.


Earthmover

Recommended Posts

Hi everyone,

I have headlined Euroserves help because it will require some specialist knowledge to assist me. I have made a rather silly mistake, in that I changed the oil and filter on my Fiat 2007 3Ltr, only when I had put the new oil in did I realise that I had not changed the sump nut washer and yes it was leaking ever so slightly. instead of biting the bullet and draining the oil back out then fit the new washer, I choose to tighten the sump nut a bit more!!. It still leaked.so I drained the oil out and put the new washer on, but something is still leaking slightly. Have I torn the weld on the sump boss.?

If I need a new sump has Nick any idea of cost and part numbers, plus the gasket. Will a eveco be cheaper than Fiats list prices?. I have got to take it to the man with the spanners and the 8 metre hoist to be sure what the exact problem is, but I want to be prepared for the worst.

Regards Em.

The sump plug on a 3.0 engine has a rubber o'ring that sits in a recess. You have probably dropped the o'ring and put the plug back in without it. It will leak.

 

Now it get's complicated.

If you order a new o'ring for your vehicle from Fiat, it will come as a washer and it will be useless. They messed up the part numbers years ago and never got round to sorting it out!

You should ask your nearest Iveco dealer for a sump plug and washer for a 3.0 Daily. They will sort that out for you.

If the sump plug was spinning around and you suspect the thread is had it on the sump, you will need a sump specifically for a Fiat because the Daily ones are a different shape (due to the gearbox type).

Fiat ones are very expensive and, frankly not that good. The paint is normally only a hair thick and is often scratched! The after market ones for 2.3's that i have seen on Ebay are pretty good and come with a new gasket which saves even more money. If you can find one for a 3.0 i would expect it to be fine. New sumps will always come with a plug and washer.

I recommend rubbing the paint down lightly and then etch priming followed by spray underseal for a longer life.

On the brighter side; you would more than likely have had to replace the sump after 7 years or so because they rot like you would not believe.

 

Part numbers are not important because as long as it says it's for a 3.0 it will fit. All the same from 2006 to 2017. I can't look up the numbers right now but if you need them i can do that tomorrow.

 

Hope this helps.

At last their are contributors who have the insight what happens under a fiat engine. It forms part of a underbody platform of a motorhome which like a car is brand new and shining like a new dime when rolling the production line. Afther that it is mostly covered whit moist. However have a good look what happens there at regular intervals. There is one bolt on the fiat subframe L/R to the chassis which is a real mystery how it it is fixed.

Hi Nick,

Thankyou for your promt reply, I am confident that the sump nut and thread is ok as is the the thread on the actual sump itself. it tightens up, so much so, that i did wonder if i had over done it and torn the metal round raised boss and the actual sump, I don't think i have but can't be certain. As to the condition of the sump it seem to be in show room condition!!. With regard to an O-ring I have changed the oil on this Vechicle at least 10 times and been given various types of washers, aluminium, copper, etc which my frendly storeman says are the correct, the latest is like hard putty between two two thin washers. Never an O-ring which as you have explained is not surprising. Can't remember seeing any recess in the sump nut to take an O-ring?, I will try buy a new nut and O-ring from Ivenco, will report back on how i get on. Thanks again.

Regards

Em.

I have some here. The plug part number is 4847102. The o'rings are in a bag with no number on it. Just ask the Iveco dealer for 4847102 and the o'ring for it. They will sort you out with the right one. Common as muck at the dealer's because they are used on most of the trucks too.

Hi Nick & Derek,

Thank you for the Info and part numbers, I have ordered a new sump nut and 4 washers from the local Iveco dealership, (not in stock) should have them Monday/Tuesday next week. Just in case it's anything more serious, I priced up a new sump at my Fiat branch, they had to get the smelling salts out to bring me round.

Cheers Em.

Should you need a new sump, they are advertised on Ebay for about £77 which will be an after-market one but i would not worry about that at all. It might be better!

One of the vendors is Coastal Motorhomes whom i have had many dealings with and can be trusted to get it to you quickly and the items are always of a good quality.

Hope you don't need one though.

Hi Chaps,

Picked up the nut and washers to-day and the nut is different to the one fitted at present!. The new one has a recess in the flange to take the O-Ring, as described by Nick, on the old one the meeting surface is just flat, no recess?. Will fit it to-morrow weather permitting and cure the problem?, unless it's something more serious.

cheers Em.

Happy new Year to Everyone 2018.

Just glancing back through my diary for 2017 and noticed that I have not posted an up date on the leaking oil sump problem. After convincing myself that I had indeed cracked the weld/brazing round the sump flange, I booked it into the man with the spanners and hoist. Oh, dear you have over tightened the sump nut and cracked the weld ####### (well something like that). You have got a choice, I can take the sump off and weld it (5 out the last six he had done were successful) or a NEW sump, I opted for a new sump. The cost for a new sump, gasket, new oil and oil filter plus labour was less than the cost of just the sump at a Fiat dealership. I think he will be changing the oil and filters from now on.

Cheers. Em

Over the years in one of my lives I welded many damaged threads in sumps. Provided the operator is aware of what damage can occur with heat expansion and cooling its a simple job, all that is then needed is to drill and re-tap a thread.

 

Admittedly the alloy mixtures used now are perhaps not so giving as they were previously !
