Hi guys looking for some help. I have a 2011 500 1.4 petrol. it has 75k on the clock. It has been in the garage for almost two weeks after going in for a new timing belt and waterpump plus the replacement of the sump which had corroded.
the problem is with the new sump. the mechanic has now put in two new ones with different sealants and there is a leak coming, he says from near where the fly wheel is.


he seems to be stumped and I cant find anything about this when I search for it.


Has anyone any idea what might be the cause of this?


cheers

From what I have learnt about gasket-less sumps is that the sealant should be applied but the sump fixing bolts Not torqued up fully until the sealant has 'gone off' to form a sort of 'sealant Gasket' as if you torque it up while the sealant is fresh then you will effectively squeeze most, if not all, of it out and in the places where the sump and block fit together the tightest most sealant will be lost and this is prob where it's leaking from actually! But your mechanic should be aware of this!

i would make sure the sump mating surface hasn't been distorted..make sure all old sealant has been removed...reseal with good quality sealant (our guys like the forte' stuff) then refit sump and wait a minimum 4 hrs. before adding oil (overnight is good if u have the time)...all surfaces have to be clean, dry, & oil-free beforehand.

Or the crankshaft oil seal is weeping

I had a similar problem with an after market sump last year for our 2011 1.1. The garage could not get it to seal and it leaked from the flywheel end, so we bought another one from Fiat (arm and leg price). However, it fitted perfectly and has been dry ever since. It seems that the aftermarket items are not always produced to the same fine tolerance as the original, which is especially critical at the flywheel end where there are no bolts.
With hindsight, I wonder whether it would have been cheaper to buy an original equipment part from Ford!

We have a pattern part one fitted before we collected the car I agree there's evidence of minor leakage at the fly wheel end not enough to drip though.

Fitting 2 sumps.. with 2 different sealants..

Sounds like they have not been leaving the sealant to bond..

As stated
a different issue is always possible.

I did one 10 years ago.. ( with the wrong sealant..) after 3 attempts I fitted a rubber wiper blade at the crank end.. slowed the leak to a tolerable level.

These sumps tend to use a huge bead of sealant.. and should be right 1st time.

Do keep us updated
